We all know how annoying it can be when a Volvo service light or any other light on the dashboard refuses to go away, even after just taking your car to the mechanic. If you’ve had experience with this issue don’t hesitate offer up some advice.
Volvo 850 Service Light (1993-1995)
- There are two diagnostic units(it says A and B on the cover) located adjacent to washer reservoir under the hood. Turn on the ignition and open the module A and insert the flylead into socket 7.
- Press the button on the diagnostic unit 4 times, briefly but firmly. Then the LED illuminates and stays illuminated, and the system is ready to accept manual code input. A code number for resetting the service reminder light is 1-5-1. To do this, press the test button once and release it And LED illuminates again.
- Then press 5 times and wait for the LED to illuminate.
- Press the button once and LED should flashes several times in succession and the reminder should have been reset.
- Switch off the ignition and replace the flylead in its holder and close the cover.
I have an S-60 T5 (2002) and the following worked for me…
1. Turn the ignition key to position I.
2. Ensure that the trip display is on T1 and shows some miles (not zero). Press and hold the T1 reset button and wait for the odometer to set to zero.
3. Turn the ignition key to position II, and watch the odometer.
4. When the previously displayed miles reappears, release the trip reset button.
HOWTO: Reset Service Reminder Indicator on 1998-2009 VolvosTuesday, August 25, 2009
Some 1998 and older models require a OBDII service light reset tool. You can probably have it reset for a marginal cost by a local Volvo dealership or Volvo specialty shop that has one of these tools.
