Re: Help with service light[850/1995] posted by Leo Montreuil on

If your car is a 1995 or before you can reset the service reminder this way:

[Procedure for Zeroing Service Reminder Indicator]

1) Turn ignition on [do not start engine].

2) Select position 7 on Diagnostic Connector A [you'll find the diagnostic
box by the left headlamp under the hood...pop the cover off and plug the
fly-connector into slot 7].

3) Depress the button four (4) times, shortly but distinctly.

You now have entered test mode 4.
When the LED emits a steady glow, system is ready to accept code.
Code 1-5-1 = zero service timer
[AllData refers to each sequence of button presses as 1 digit]

4) Enter first digit [1 press] while the LED is still glowing. Wait until
LED starts to emit steady glow again before entering second digit [5
presses]. Repeat procedure for third digit [after the five presses wait for
the steady LED glow again and then press the button one final time].

5) Wait for confirmation from control module by LED giving a couple of
rapid flashes. Zeroing is completed and Service Reminder Indicator is Off

[6) Switch OFF the ignition to exit the manual input mode, replace the
fly-connector in its holder and refit the diagnostic unit cover.]

[7) Switch ON the ignition again and check that the service reminder light
does not illuminate.]

The indicator lamp illuminates for approximately 2 minutes each time the
engine is started until service has been performed and counter reset.
