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).

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).
