Service Engine Light 900 1996

posted by  someone claiming to be Bobby C. on  Sun Dec 29 12:01 CST 2002 [RELATED]

My '96 OBD II equipped 965 has started illuminating the MIL light (Service Engine Soon light) every time it is started when warm.

It illuminates when the key is "on" (as do all the warning lights) and stays illuminated after the starter is disengaged (never goes off during/after crank and start sequence).

It goes out almost exactly 4 minutes after the engine has been running every time.

My understanding was that once illuminated, the light should stay illuminated unless the fault disappears during a number of cycles.

I have an OBD II code reader (INNOVA Equuis 3100) that I need to hook up to read the fault/s storred in the computer, but before I do this I thought I'd ask if anyone has had a "light's on...now it's off" condition, and if so what it was found to be.

Thanks,
Bob

    If the light says "SERVICE", it is simply an oil change reminder that comes on at 10K intervals. It does not indicate a problem. If it says "CHECK ENGINE", it indicates a malfunction.

      Thanks!!

      I should have caught that. My "Check Engine" light does NOT illuminate when the ignition switch is "on" (but engine not running), so it was invisible, so I assumed that the Service light WAS the MIL light (On my last car the MIL light was labelled the "Service Engine Soon" light.

      Obviously I should have read the owners manual before posting here!

      Now I guess I have to pull the cluster to replace teh "Check Engine" light.
