RESETTING 5000 MILE SERVICE LAMP ON 1994 + 1995 850
NOTE: This function is for the service reminder lamp, be sure you have performed the proper service such as changing the oil before resetting. If the check engine lamp is illuminated when the car is running, you’ll need to have the car looked at by the Volvo dealer for proper diagnosis.
1. Turn on the ignition to the KPII position so the warning lamps on the dash are illuminated. Do not start the car.
2. Open the bonnet of the car and locate Diagnostic test port (A) behind the driver side headlamp.
3. Remove the cover and pull the jumper wire out of the holder in the cover.
4. Insert the jumper into terminal #7, then press button 4 times, wait approximately 5 seconds and the red lamp should glow continuously. You are now in the data reset mode.
5. Press the button 1 time and wait approximately 5 seconds for the lamp to glow again then press the button 5 times. After about 5 seconds the lamp will illuminate again, press the button 1 time and you will see the lamp flash repeatedly for a couple of seconds indicating that the service lamp has been properly reset.
6. If a mistake is made, simply switch the ignition off and back on to reset and start over.
1996 Model (Some of them)
On these models the diagnostic socket is in front of the gear stick. Switch the ignition on. As you look at the speedometer on the dash, beneath it opposite the trip reset button is a rubber plug. Remove the plug and with a thin pointer such as a ball point pen, depress the pin. This will reset the service light.

The service light on these vehicles is usually a spanner / wrench symbol. To reset that indicator:
Turn the Ignition ON (position 2) but do not start the engine
(On cars with keycard ignition, insert the card, then press and hold the start button for 5 seconds to turn on the dash cluster)
Press the button on the end of the wiper stalk repeatedly until the spanner symbol and miles to service appears on the display
(Some models have 2 buttons, which cycle through the options in opposite directions – either button can be used in this case)
Press and hold the button
The display will now change to the new service interval and start flashing
Keep holding the button until the display stops flashing
Release the button
To reset the service indicator on the scenic II is as follows:
Scroll through the trip computer using the button on the end of the right hand stalk control until you get to the miles till service indicator (or the “change oil soon message” will appear if due)
Then press and hold the same button in and hold it. The miles indicator will then flash then change to 18000, keep the button pressed until the 18000 stops flashing.
NOTE: If the word “service” appears on your dash then that does NOT mean that a service is due. It is an indication that the vehicle is faulty and has a stored major fault code.
The indicator that a Service is due is when the words “change oil soon” appears or the spanner starts flashing.
