Had the PNP set off the "arrow" lite a couple of thousand miles ago and since I have previously replaced the PNP I just did the rapid gear selector routine to get it back working and been great ever since. Except of course the CEL has been on. I had planned to get the lite reset in December when it goes to the Indy for state inspection. Lo and behold today I notice the CEL is not longer illuminated. Yes, I did a bulb check and it is alive and well. Coincidental, but not related to the CEL, the Service lite has also been on for a few miles/minutes and then going out as it should. Since I do all the maintenance I am used to it coming on and having the Indy reset it also during inspection if it is needed.
Is there a reset software that determines you have more patience than Volvo engineers ever imagined and it concedes defeat? Or do I have a gremlin? Or did someone take my car to the dealer unbeknownst to me?
It is a 1996 and I have had it since new. Have never seem this before. Has anyone else? I have always read the CEL could only be reset by thru the OBD outlet. I have tried several times over the years to reset it with a battery disconnect, some lasting 24 hours, and never had any success.
