Below is the list of Volvo TNN's for the 2004-2007 R, I have accumulated over time and was maintaining on http://www.v70r.com/forums/index.php . In the spirit of cooperation, I am offering these to Swedespeed for your use. If you find this useful then I will continue to update them here as well on http://www.v70r.com/forums/ind...=2025 . Due to size I had to split the information into 3 posts.

Please Note: Alldata the company that provides the "Details" of the TNN has stopped providing the information for free. To obtain the complete TNN you can go to https://www.volvotechinfo.com/index.cfm?eve...scriptions.main and sign up for a 3 day subscription of "Subscription - Tech-Net-Notes" for a very reasonable cost of $4.00! During your subscription period of 3 days you will be able to download as many complete TNNs as you want. I have included the Volvo description of each TNN to help you in your decision on whether to purchase the complete TNN from Volvo.

As available, I will update the Volvo TNN's for the 2004-2007 V70R.

NOTE: Many Dealers track their TNN's only by TSB number. The TSB# is the first set of numbers in front of the TNN date, for example on TNN25-21-2004-07-21, the TSB # would be 25-21.

Current list of all TECH Notes as of 5/3/2006: TNN List

Volvo Model designation:

285 = 2001- Present V70
295 = 2001- Present V70 (Cross Country)
384 = 2001- Present S60

The TNNs are organized under the Categories: General, Engine, Transmission, Suspension, Electrical and Audio. Within each category they are in ascending order by TNN#

GENERAL (Warranty, Adjustments, Headlights, Interior, Speed Limit, Battery, Seats, Rain Sensor, Fuel Tank Filing)

SMB00-235-2005-10-10 Title: VCNA Policy on Non-Genuine Parts or Accessories
Details: Warranty Policy

Top Speed Limit Correction- software update code P/N 8633830 to correct the speed limit problem on the US spec V70 R from 130 mph to 155mph.

TNN23-25-2006-07-31 Title: Difficulties when filling the fuel tank
Under certain conditions the customer may experience difficulties while filling the fuel tank. Should a customer experience this condition and the vehicle falls within the listed engine codes and chassis ranges (below), a hose clamp (part number 988010) can be installed at the flapper valve assembly located inside the fuel tank. The flapper valve is connected to the bottom of the filler pipe and the clamp is designed to secure this connection.

TNN28-66-2006-07-07 Title: ECM DTC 434C Fuel tank system, leakage; Minor leak
ECM DTC 434C may be set in the above vehicles due to an over sensitivity in the engine management software.

TNN31-06-2004-02-24 A new battery mounting bracket and positive terminal protection has been introduced on 2004 S60, S80, V70, and XC70 vehicles as a running change. See photo. As a result the battery cover and the associated hardware have been deleted and should not be installed during Service.

TNN35-14-2004-03-08 Title: Bi-Xenon Headlamp Ballast
Under certain conditions, ballasts in vehicles equipped with Bi-Xenon headlamps may not function. The ballast functions as the voltage regulator and generates alternate current. It transforms the vehicles current from 12V to 1,000V during startup. Once the bulbs are lit, it then reduces the voltage to 100V. Its main tasks are to light the bulbs and to control the light during operation. New improved ballast has been introduced into production from the chassis break shown.

TNN36-38-2004-10-27 Title: Rain Sensor Function
This Tech Net Note is intended to provide additional information about the Rain Sensor and its functionality, now a factory option available on 2003 vehicles

TNN36-56-2006-08-03
Title: Automatic Locking System - Activation and or Deactivation - Can be activated by 2007 Owner's without Software Download.
From MY2007, SW download is not required to activate/deactivate the automatic locking function. This can be done by the customer via the central locking button on the driver's side. If the function is activated, the doors lock automatically when vehicle speed exceeds 5 mph (7 km/h). The doors will remain locked until a door is opened from the inside or unlocked using a central locking button. (Note: Opening one door from the inside will not unlock the other doors. Each must be opened from the inside individually, or the driver can use the central unlock button on the driver door control panel or the remote control.) Unlock an auto-locked trunk or tailgate with a central locking button, or by pressing the Unlock or Trunk/Tailgate Unlock button on the remote control. The function is also described in the owner's manual: Locks and alarm/ Automatic locking

TNN37-27-2004-03-12 Title: Driver Information Module Software

TNN38-16-2006-07-21 Title: MY 2006 SRL (Service Reminder Light inoperative)
Due to a fault in the DIM programming from the factory on the indicated vehicles, the SRL will not illuminate at the specified mileage or global time for the first service interval (7,500 miles or 1year). Engine hours are not affected.

Once the SRL reset is performed at the CPS (Customer Preparation Service) or 7500 mile
service, the DIM (Driver's Information Module) mileage and global time counters will operate normally and the SRL will illuminate at the proper intervals.

TNN37-35-2006-05-23 Title: CEM harness terminal corrosion due to water entrance in plenum
Various electrical function and communication symptoms may occur in M/Y 2005-2006 vehicles caused by wet corrosion in the CEM (Central Electrical Module) connector. The grommet that seals the harness entrance to the Plenum box may not seal properly if it has been incorrectly assembled. This may cause a number of different functionality symptoms and DTC's to be set.

Examples include but not limited to:
Headlight on, even if ignition key is taken out of ignition lock.
Warning messages in DIM (Driver's Information Module) display.
Warning lamps lit up.
Brake lights always on.
No start condition.

TNN43-45-2004-06-04 Title: Ignition Interlock Cable Clip
The yellow plastic ignition interlock cable clip can be damaged when it is unlocked to perform a repair. Because of this, it should be replaced with a new clip (PN 30711794) whenever it is unlocked. Future VADIS versions will reflect this change in repair method.

TNN80-03-2003-09-22 Title: BODY/INTERIOR ELECTRONIC MODULE SOFTWARE UPGRADE models/years
In the event that a software upgrade is specified for any body and interior electronic control module the software product numbers in this TNN must be used, and in all cases supersede all Function I D (FID) information previously supplied.

TNN85-26-2005-07-15 Title: Interior - Power Seat Rocks Fore and or Aft on Accel and or Decel
On cars equipped with power seats, a small fore and aft or rocking movement of the seat during acceleration and deceleration might be experienced in certain cases. This Tech Net Note describes how to reduce this movement in case of a customer complaint.

TNN85-28-2006-03-03 Title: Front Seats, Play in Lower Part of Backrest/Adjust (2005- )
Some customers may complain about play in the lower part of the front seat backrest. The concern occurs mainly during stop and go driving. Sometimes the play is combined with a knocking noise that can be heard from the recliner area.

TNN87-53-2005-11-21 Title: Air Conditioning, 'Afterblow' Function.
Under certain conditions, customers may complain about a musty odor from the A/C system. Activating the afterblow function will minimize this from occurring.

TNN87-54-2005-11-30 Title: Temperature Coming Out of the Climate Vents may Start to Cycle from Max Hot Back to Full Cold When Max Hot is Requested.
If the temperature knobs are turned to max hot, the temperature coming out of the climate vents may start to cycle from max hot back to full cold with a period of 4-15 seconds. No Diagnostic Trouble Codes (DTCs) are stored. The number of steps on a temperature Damper Motor Module (DMM) may have increased from factory settings, causing the affected DMM to set a "not calibrated" flag to the Climate Control Module (CCM). This causes the climate system to self-calibrate over and over again resulting in the cycling temperature from the vents.

TNN87-56-2006-12-11 Title: Whistling Sound from Windshield / Dashboard Area, Passenger Side
If a whistling sound or wind noise is heard from the passenger side dashboard area of the cabin. One reason for this may be that the foam sealing between the body and climate unit (air inlet) is incorrectly positioned. The sound may vary in strength but is more audible at higher speeds; 50 mph (80kph) and above.

ENGINE (ETM, Crankcase Ventilation, Low Boost, ECM Software)

TNN20-04-2007-01-22 Title: Engine Management Software Upgrade
Reference: Tech-Net Note 00-87
To support the features provided in the PIE 2 software part ordering system which take effect with VADIS version 2003 C/D it will be necessary to refer to existing Tech-Net Notes for symptom, diagnostic and procedural information. In the event that a software upgrade is specified for an engine management related control unit the software product numbers below must be used, and in all cases supersede all Function I D (FID) information previously supplied.

ONE SOFTWARE PRODUCT NUMBER WILL BE USED FOR ALL VARIANTS IN A PRODUCT RANGE. i.e. model year, turbo/non turbo, control unit mfr. etc. The confirmed download of an upgrade software product assures that all of the latest software for the module specified has been successfully delivered to the vehicle.

If the message invalid is received during an order, the control module may already contain all of the latest software. Always consult VADIS software order operations "details" for additional information

TNN21-21-2005-08-15 Title: Engine may have a rough idle, DTC ECM misfire codes, rough running or lack of power.
The Customer may have a complaint of a rough idle, rough running, lack of power or the MIL on.
• Read out DTC's
• Check compression and do a leak down test with the engine cold.
• Check valve clearance on the cylinders with low compression.
• Remove the cylinder head and check the condition of the valve face.
• If the valve face is worn, replace ALL the intake valves, even if some look okay.
• Use ONLY intake valves with P/N 30637059.

TNN25-149A-2006-07-07 Title: Troubleshooting the Electronic Throttle System (ETS).
The fault tracing for ETS codes in VIDA has been enhanced to include more background information on Faults sub system and the criteria for detecting a fault. Where applicable if there are differences between the original software's fault detection criteria and the new ETS software (March 2006 and later) the differences are described in the fault code information.

TNN25-149B-2006-02-20 Title: Checking the Crankcase Ventilation System.
This TNN describes a new method for checking the functionality of crankcase ventilation.

TNN25-149C-2006-02-20 Title: Cleaning the Crankcase Ventilation.
This TNN is an update of the existing method for cleaning the crankcase ventilation system shown in SB 25-0035 February 2004.

TNN25-149D-2006-02-20 Title: Cleaning the Crankcase Ventilation and Electronic Throttle Module.
This TNN describes the method for cleaning the Crankcase Ventilation and Electronic Throttle Module (ETM). Cleaning must always be preceded by fault-tracing according to Vida and TNN 25-149-A.

TNN25-149E-2006-03-03 Title: Electronic Throttle Module (ETM) Replacement.
This TNN describes an update of the existing method for Electronic Throttle Body (ETM) replacement. Replacement must always be preceded by fault-tracing according to VIDA and TNN 25-149-A.

TNN25-149F-2006-03-16 Title:Title: Electronic Throttle System Software
Beginning March 17th 2006 there will be an Electronic Throttle System (ETS) software upgrade available for the vehicles listed above. The software contains changes that will reduce driver disturbances by allowing the system to better differentiate between glitches or minor disturbances, and system faults. The upgraded software will also reduce driver disturbances due to idle oscillations caused by dirt build-up in the throttle. TNN 25-149A will be updated to guide service technicians on the changes. The fault tracing for each DTC in the TNN will give guidance on where it is appropriate to use the software as a solution for DTC's triggered in the vehicles current software. As the ETS software resides in both the Electronic Throttle Module (ETM) and the Engine Control Module (ECM), both will receive new software with the upgrade.

TNN28-48-2003-06-23 Title: Poor driveability after cold start on MY 02 5-cylinder non-turbo engines may be experienced.

Initial start is always good, but the following symptoms could occur after start:
1. Rough running / misfire during idle just after cold start.
2. Stalling when coming to a stop, most common during engine warm up but also possible with engine at operating temperature.
3. Hesitation / stalling during engine warm up when the vehicle is put in gear and light throttle is applied

These conditions can be caused by faulty operation of the CVVT function.

TNN28-67-2006-04-21 Title: Engine Controls - MIL ON and or DTC 275C and or Low Turbo Boost\
DTC 275C "Engine Coolant Temperature Sensor Signal Too High" may be wrongly triggered in any of the above vehicles, under the following driving conditions:

1. Vehicle driven short distance after cold start.
2. Engine turned off for short time, and then re-started while still warm.

DTC 275C will result in the following:
1. Check engine lamp illumination
2. Temperature gauge will read zero
3. Turbo boost will be limited.

TNN28-68-2006-04-21 Title: DTC 436B "Leak diagnostic unit - signal missing"
DTC 436B "Leak diagnostic unit - signal missing" may be incorrectly set in any of the above vehicles due to an over sensitivity in the engine management software. If the Engine Control Module (ECM) software part number is one of the following:

30771287 30771288 30771289 30771290 30771291 30771292 30771293
30771498 30771499 30771500 30771501 30771502 30771503 30771504

Upgrade the ECM software as described below, then test the system using the "quick-test of the fuel tank system" via VIDA vehicle communication, fault trace any faults according to VIDA. If the ECM software part number is anything other than one of the above, the upgrade has already been applied, and DTC 436B should be fault traced per VIDA.

TNN28-145 Title: Recall - Software Upgrade for EVAP System Performance
Certain model year 2005 S60, S80, V70, XC70 and XC90 vehicles do not meet the requirements of the Environmental Protection Agency (EPA) and the California Air Resource Board (CARB) for removing pollutants from the Evaporative Emissions System. The requirement only pertains to purge performance and does not affect the safety or drivability of the vehicle. However in certain cases, this may cause the vehicle to fail a state inspection or Smog Check test.

The corrective action will be a software upgrade of the Engine Control Module (ECM).

Re: VOLVO TNN Reference List (defgh1)

TRANSMISSION( Automatic, Manual, Angle Gear)

TNN40-02-2006-09-25 Title: Engine, Auto Trans Controls - DEM and TCM Software Updates
Update for General Shift Quality on 2002-2006 Automatic Transmissions.
The TNN defines TCM and DEM software Upgrades that are available to correct the complaints / symptoms listed.

TNN40-04-2005-10-13 Title: Auto Trans, Manual Trans, AWD - Approved Lubricants Authorized Lub

TNN43-27-2004-01-22 Title: AW55-50 Adaptation Procedure.
The AW55-50 gearbox relies on adaptive data to properly adjust its shift pressure. This data is collected and memorized by the TCM and then used to adjust shift feel/quality. If the adaptation is not complete, it may result in:
- Shift Flare: Engine RPM increases during a shift. This symptom often feels like the car has temporarily lost drive or the transmission is slipping. It is usually the 2-3 upshift that flares the most.
- Harsh Down Shifts: Harshness felt during a coast-down shift (zero throttle downshift).
- Harsh Garage Shifts: Harshness when shifting P-D, N-D, P-R, or N-R while at a standstill.
- Harsh Neutral Control Engagement/Disengagement: After coming to a complete stop in Drive, with your foot on the brake the TCM waits 2 seconds and then disengages drive to reduce emissions and minimize idle vibrations. This disengagement is normally smooth and isn't felt by the driver. If adaptation is not complete then a "thud" can be felt in the car 2 seconds after coming to a complete stop. When the brake pedal is released, the re-engagement of Drive should be relatively smooth. A harsh re-engagement can be felt if the adaptation is not complete. Neutral Control is present on all 2001 MY S60s and V70s. It is also present on nonturbo 2002 S60s and V70s produced before January 2002.

TNN43-38-2006-02-09 Title: AW55 Neutral Control Function
A function called 'Neutral Control' is present on all 2001 V70 and S60 cars. It is also present on 2002 non-turbo V70 and S60 cars built before January 2002. When the vehicle comes to a stop, the Transmission Control Module (TCM) activates Neutral Control. Even though the gear selector is in the Drive position, a Neutral condition is engaged hydraulically in the transmission. Neutral Control disengages when the brake pedal is released or the throttle is applied.

When the neutral control function is incorrect, there are three symptoms that can be felt in the car:
1. After coming to a complete stop and keeping the brakes applied, a "thump" can be felt in the car. It is felt about 2 seconds after coming to a stop.
2. When releasing the brake there is a harsh or double re-engagement of drive.
3. When idling in 'D' range with the brake applied, the engine speed oscillates (fluctuates).

TNN43-40-2004-03-03 Title: Buzzing Noise from M66 Shifter, S60R/V70R.
Some customers may complain of a "Buzzing" noise from the manual shift lever in S60R / V70R cars. The noise is most easily heard when accelerating at high engine RPM (3000 RPM and higher). Applying light pressure to the shifter by hand will make the noise disappear.

TNN43-42-2003-12-12 Title: TCM SW Upgrade, 2-3 Upshift Flare.
MODEL/YEAR: MY 03-04 S60 / V70 / XC70 / S80AWD / XC90 with AW 55 transmission.
Model year 2003 & 2004 S60, V70, XC70 and XC90 cars with the AW 55 transmission may experience '2-3 upshift flare'. This shift flare may be described by the customer as the transmission slipping; the car feeling like it was in neutral for a short time, the tachometer needle jumping up or the engine racing during a shift. Quality Upgrade software has been developed to minimize this condition.

If a customer has a complaint that matches the above description, Upgrade the TCM SW (software product number 30677036). This SW is very similar to the original SW in the TCM, so the Adaptation should NOT be reset to zero. The car should then be test driven according to the adaptive test drive found in VADIS.

Model Chassis No.
S60 - 378262
V70 - 411253 factory code "1" - 410423 factory code "2"
XC70 - 149389

XC90 - 082566

TNN43-47-2005-11-01 Title: Difficult to engage 1st and/or
reverse gear.
MODEL: Vehicles with 5 or 6 Speed Manual Transmissions, M. YEAR: 1999-2005
Some customers may complain that it is difficult to engage 1st and/or reverse gear, especially after the car has been sitting overnight.

This Tech Net Note supersedes the previous 43-47, dated 8/5/04. Please update your files. This applies to all 1999 S/V/C 70 cars, as well as S40/V50/S60/V70 cars built before: 544 -053404, 545 -048974, 384 -425275, 285 -459438

TNN43-48-2005-12-20 Title: Coolant Contamination in Automatic Transmissions
The root cause for some automatic transmission failures is glycol contamination from the engine cooling system. Severe cases of contamination are easy to detect by a visual inspection: The transmission oil will have a milky appearance and there may be signs of oil in the coolant reservoir. Less severe cases are impossible to detect without doing a chemical analysis of the transmission oil. This slight contamination is easy to overlook and will result in a repeat transmission failure. A small leak from the cooling system into the transmission can cause driveability problems long before there are any visual signs of contamination.

TNN43-49-2006-04-06 Title: AW55 TCM DTC 010A, 010B, 010C Shift Solenoid S5 signal low, high or missing.
A likely cause for a DTC related to the S5 solenoid (010A, 010B, 010C) in the AW55 transmission on a model year 2004 or 2005 vehicle is a broken wiring terminal at the solenoid

TNN43-53-2006-12-21 Title: Auto Trans - TF80-SC Diagnostic Information Summary - Valve Body Replacement.
This document summarizes customer complaints related to the 6 speed Automatic Transmission (TF80-SC) and should be used together with the information in VIDA.

The Valve Body should be replaced to address the following symptoms:
1. Customer complaints about 2-3 upshift quality. The shift may be described as harsh, or as a shudder. The symptom is usually more apparent during the first few minutes of driving after a cold start.
2. Customer complaints of shudder when slowing down, just before coming to a stop. The symptom may also be described as a harsh downshift just before coming to a stop.
3. Neutral condition in 4th, 5th & 6th gear; normal behavior in 1st, 2nd, 3rd & Reverse. One or more of the following DTCs (Diagnostic Trouble Codes) may be present: P073400, P073500, P072900, P089600.
4. Neutral condition in all gears except 5th & Reverse, usually with DTC P273300 set. DTCs for gear ratio(s) may also be set such as P073000, P073100, P073200, or P073400.
Note: Transmissions starting with serial number 06J and later already have the latest valve body which is designed to prevent these symptoms.

TNN46-08-2004-03-10 Title: Oil Weepage from Angle Gear Vent.
If oil weepage is found at the Angle Gear Vent, a new vent valve should be installed.

TNN17-21-2003-05-08 Title: Transport Spring Spacers
Transport spring spacers will be installed on both the V70R and the S60R during vehicle transport. Prior to driving these vehicles above 15 mph, the spring spacers should be removed.

TNN21-18-2004-05-04 Title: Sub Frame Squeaking Noise.
Under certain conditions when driving in cold and or wet weather a squeaking or crunching type noise may be heard from the vehicle sub frame bushings.

This noise may be more noticeable during low speed maneuvers or when braking at low speeds. From the chassis break point listed below a new insulating washer PN 30660816 has been introduced in production and is available as a service solution. If the customer should experience this condition and the vehicle is below the chassis # listed the sub frame washers should be installed.

TNN25-21-2004-07-21 Title: High Pitched Squealing Noise, Exhaust Touching Propeller Shaft-- I DO NOT recommend this one, either replace the resonator with a straight pipe or lower exhaust with washers between the hanger brackets and chassis!
Exhaust Conflict with prop shaft (location rear lip of front muffler). DESCRIPTION: Under certain conditions when driving through puddles of water, slush and or snow, the underside of exhaust system may cool down fast enough causing the exhaust to change shape and touch the propeller shaft, causing a very high pitched squealing noise. This noise will be noticed by the driver for only a short time, once the exhaust temperature equalizes the noise will disappear. If the customer should have this complaint a tell tale mark will be left on the propeller shaft

NO: 76-04 CHASSIS: 285 0349395 -384 0315516
A noise from the rear shock absorbers may occur when driving over small road disturbances.

The SUM (Suspension Module) should be loaded with the new SW Quality Upgrade, FID 950(P/N 8691393). To check if FID 950 (P/N 8691393) has already been downloaded to a vehicle, the unique SW P/N 30669894 should be able to read out from the SUM via VADIS. The SUM has to be calibrated after downloading this software. See VADIS for procedure: Vehicle Communication/ Group 7/ Suspension Module/ Calibrating the system.

NOTE! The Headlights need to be in the on position prior to calibration; if the headlights are not turned on during calibration they could be set out of position.

TNN77-08-2004-03-25 Title: Front Axle Ping Noise
When performing garage shifts (Drive to Reverse / Reverse to Drive), the hub axle interface may make a ping type noise. This noise may also be heard while cruising and changing from acceleration to deceleration. Note: For those who have had no luck with the metal adhesive fix should request the axle bolt specified in the XC90's TNN77- 09.

TNN77-11-2005-01-13 Title: Wheel Bolts Corroding.
Under certain conditions the wheel bolts may have evidence of surface
corrosion. If you should have a customer concern with this issue and the vehicle falls within the chassis range listed below, please install wheel bolt caps (kit PN 9139853).

TNN81-04-2003-07-29 Title: When lifting a vehicle it is important to use the proper lifting locations and procedure as defined in VADIS. These locations are designed to support the weight of the body when lifted. If not lifted correctly, the body can deform and in some instances create an "oil can" like popping noise when the body is flexed (i.e. when in motion).

TNN81-05-2004-03-10 Title: Knocking noise when turning
A knocking (or clicking) noise may occur from the front of the vehicle when turning, slowly going over bumps, and/or entering an inclined surface (driveway, parking lot etc.). The noise usually occurs when the body undergoes a twisting (flexing) motion. The noise can originate from the bumper rail contacting the front side member(s).

ELECTRICAL (Alternator)

TNN32-02-2005-05-09 Title: Alternator Charging Problems.
Analysis of damaged alternators shows that the regulator may get damaged due to extreme weather conditions with high temperature and high humidity. The regulator may fail in two phases.

TNN32-03-2005-07-14 Title: Alternator; Noisy.
If there are reported cases of alternator noise and/or auxiliary belt damage, it may be possible that the belt is not tracking properly.

TNN32-04-2005-12-14 Title:CEM DTC DD21 due to faulty LIN-network, Alternator Not Charging.
DTC CEM-DD21 may be set because of faulty communication between the Alternator and CEM due to the installation of extra LIN wiring for the upcoming BLIS, (Blind Spot Information System). Customers may also report an intermittent DIM message "POWER SYSTEM SERVICE REQUIRED" It may be possible that there is a pinched LIN-bus wire from the CEM to the BLIS-system between A-pillar body and the dashboard assembly on the left side.

Re: VOLVO TNN Reference List (defgh1)

AUDIO (Radio, On-Call Plus)

TNN39-28-2001-09-12 Title: "Search" displayed on HU-80x Radio
Model: S60, V70, V70 XC, and S80
Reference: Vehicle Owner's Manual
When selecting a pre-set FM Station on an HU-801 or HU-803 radio, it is possible to have a "Search" message displayed for several seconds before playing the station. HU-801 and HU-803 radios use RDS (Radio Data System). RDS allows text information to be transmitted with the radio signal. The text information is then displayed on the radio display. When stations which transmit an RDS Signal are memorized, some RDS information is also memorized. If the radio signal is weak, the RDS information may be unrecognizable to the radio. When the radio is unable to decode the RDS signal for a pre-set station, it searches for the RDS profile, thus entering the "Search" mode. The radio will "Search" for the RDS information for several seconds (with the radio muted), then stop searching and play the station.

If a customer complaint is consistent with the above description, it is possible to avoid the "Search" mode. SInce the radio is searching for the memorized RDS information, the station must be memorized without any RDS Signal. THis can be done in two different ways, either:

* In an area of strong signal, disconnect the radio antenna and memorize the station. (With the antenna disconnected, the radio does not received the RDS Signal, and therefore cannot memorize any RDS information).

OR

* When "Search" is displayed, memorize the station.
NOTE: Method 2 should be explained to the customer for future use.

TNN39-43-2004-04-19 Title: Grounding of Differential Electronic Module to Reduce A.M. Band Radio Interference
Owners of all wheel drive vehicles may report A.M. radio static or a crackling noise heard in areas of weak A.M. radio reception. The disturbance is especially noticeable during acceleration and can be related to the function of the Differential Electronic Module.

Re: VOLVO TNN Reference List (defgh1)

Once again, I want to give a huge round of thanks to Doug Hess.

Out of the goodness of his heart, Doug took the time to research all the missing data from the pertinent TNN's listed, and has edited the list so that the links are no longer needed.

As the top of the thread notes, if you need more information, you can go to Volvotechinfo.com and pay to print out what you need at a much more reasonable rate than alldata.com

Once again Doug, your help is greatly appreciated.
