I am looking at a 91 245. Overall in good shape except some rust above the back bumper in the rear of the car, nothing too serious. Unlike my 87 wagon, this car has a light on the dash that I think says service. This light came on when I started the car but went off after driving, the owner said it comes on because it is due for an oil change. Is that accurate or is the light on for another reason?

Re: service light (frogman)

Just a reminder - easily disregarded and/or reset.<p>Now, if the CHECK ENGINE light comes on...<p>George Dill<p>From The Brickboard (and a past Swedespeed post)...<p>---------------------------------------------------------------------------------------------<p><A HREF="http://www.brickboard.com/ARCHIVES/1998JAN/7733.shtml" TARGET="_blank">http://www.brickboard.com/ARCH...shtml</A><p><br>BrickBoard Archives<br>The files contained in this listing have been automatically archived from the active forums.

EPA standards do not include service reminder reset (this is part of the Volvo proprietary OBDII extended codes and diagnostic procedures). If you have no other choice and feel you have to defeat the OBDII reminder system then do it by removing the warning bulb (subtract 10 points from your Brick Badge). <p>up to '87 740/240 ... post-it note on rear view mirror is your service reminder <p>up to '74 140 ... putting key in ignition and having all dash lights come on is your service reminder <p>up to '68 120/540 ... having oil pressure warning light coming on as you round a corner is your service reminder light; reset by topping up with oil from pan that you keep under your parked car <p>Notes: <br>-These reset procedures are for the SERVICE warning lamp (time to change the oil) not the CHECK ENGINE lamp (time to consult with your mechanic) which indicates that a possible component failure or unusual running condition has been detected by the EFI computer. <br>-The service reminder light will come on for about 2 minutes after starting the engine once the counter reaches the service interval. Actually it starts coming on about 200 miles before the interval as an early warning. <br>-240 EGR/LAMBDA service reminder reset (US-California market only?) ... EGR valve (15,000mi) or Lambda Sond oxygen sensor (30,000mi) service reminder lights on 240's so equipped are reset with a push button on the back of the little counter box located above the driver's left knee (there's a short slave speedo cable from it to the back of the instrument cluster); Hint: if you turn your ignition on and there's no EGR or SOND warning lamp then you don't need to know this. <br>-Service lights are set for the maximum recommended routine service intervals. When you perform service, remember to reset the counter at the same time whether or not the reminder lamp was coming on. <p>If any of the above information is incorrect or incomplete, please add to this thread for future reference. In the literature I've noted a number of inconsistencies in correlating model years to the above. Variations are probably VIN range specific (production date, market code, etc.). <p>--------------------------------------------------------------------------------<br>Re: Service Reminder Light Reset Notes[ALL/1988] posted by Jim Bradley on <br>Sunday, 18 January 1998, at 9:53 a.m.<p>My '89 780 Turbo w/air bag resets through the rubber grommet hole in the face of the cluster. I don't know if the 6 cyl. is different, but the B230FT uses the procedure described for '88-on 760 and '89-on 740/940. Thanks for compiling this info. <p><br>--------------------------------------------------------------------------------<br>Re: Service Reminder Light Reset Notes[ALL/1988] posted by MARK H on <br>Sunday, 18 January 1998, at 9:26 p.m.<p>Thanks Dave Stevens: I know that was alot of work! I prefer the pre 68 method of reseting the light, I used it my self on my 140.Now I own a $300.00 reset tool that has to be sent in every year to be up dated to work on every new model year.I hate it; this is Volvo trying to make customers go back to the dealer. I feel this is going to back fire on Volvo and the dealers.When I was at the dealer as a mechanic I forgot to reset the service light maybe once or twice a week.That is with the reset button right in front of your face. I like the service light reminder but keep it simple. What happen to maintance free low cost services. It is more complicated and expensive to reset the light then doing a oil change. Every customer that comes through the door at my shop wants to know if we can turn this light off.When I say, yes! they fell like they have been unleashed from the dealer. (Dealer loses a customer I gain a customer.) <p><br>--------------------------------------------------------------------------------<br>Re: Service Reminder Light Reset Notes[ALL/1988] posted by Henry T. Mui on <br>Monday, 19 January 1998, at 2:51 p.m.<p>Thanks! Dave, <p>The 88'-on 760, 89'-on 740/940 with old style OBD (1) system you need to push the button with the engine and ignition system off! Other than that It's all correct! <p>--------------------------------------------------------------------------------<br>Re: Service Reminder Light Reset Notes[ALL/1988] posted by Paul Elliott on <br>Thursday, 22 January 1998, at 9:16 a.m.<p>I have a '95 850 Turbo, and use the method you list, and is confirmed in both the Haines manual, and Volvo srvc literature...However, my documentation, including owners manual, etc, states that this car *is* fully OBDII, not OBDI as you indicate. <p>---------------------------------------------------------------------------------------------<p>
