Procedure for Resetting the Service Interval Light on Volvo 850

Note : I have not verified this procedure - it came from someone at Compuserve

Go to the "A" on-board diagnostics terminal. It is a 1" X 2" black plastic box in the engine compartment, located just to the right of the windshield washer filler cap. Lift the top. Put the little pin, attached to the top , into socket #7. Turn the ignition on, but don't start the car. Go back to the "A" terminal and push the little black button next to the "A" 4 times at one second intervals. Wait and the light will come on.

Push the button once and wait for the light to go off, then come back on again.

Push the button 5 times and wait for the light to go out, then come back on .

Push the button once and wait for the light to flash. Remove the pin and put it back. Close the terminal.

Start the engine, and you are done for another 5K..

you can try that, i know that some older cars use this method.. unless you want to buy the reset

tool...http://www.autopartswarehouse.com/mmp/volvo~850~service_reset_tool~parts.html

i don't know the price, don't have to buy it from here.. shop around.


another one:
'92-'95 850 with old-style OBD(I) system (9300mi/1500km, 12months or 750hrs) ... with ignition on, reset at diagnostic unit under hood (right side forward) using push button to enter function code 4 then reset code 1-5-1 (morse code style holding button <1sec for each count, pause <1sec between counts, pause 3-5 seconds between digits, pause 5-10 seconds before/after function code)

note: do you have a button there?

Answer 2

Check to see if there is a reset button on the dash it may look like the odometer reset. OR Turn the key to the first position and then the second position on and off for 3 times. This should disable the light. Good Lick.

Answer 3

The easiest way, if you don't have a computer to reset it with, is to disconnect the battery for about 60 secs. then hook it back up.

Make sure that you have the code for your radio before you do it or it will stop it from working.
