Clearing service engine light?

[viperdoctor]

Hi,

I just installed the Jet Skipshift connector in my 2001 GTS to hopefully turn off the service engine light.

Well, it's still on. Does that mean that the Jet connector is not working or does it mean I just need to clear the computer to turn off the light?

If I need to clear the computer, how do I do that on a 2001? The archives made it sound like some cars can be cleared by disconnecting the battery...

Thanks,

ViperDoctor

Ugh.

1) I tried reading the codes with the on/off/on/off/on sequence and nothing. I guess that doesn't work with 2001's either.

2) Tried disconnecting the battery to clear the check engine light. Didn't do it. Guess that doesn't work with 2001's either.

3) Took out JET skipshift and put back original connectors. Still have check engine light.

Ugh. I can't read the codes to know for sure that the check engine light isn't from something else. Can't get rid of the light...

Any ideas?

-Your right, that doesn't work.

The PCM will check and monitor all of the sensors. If the skip shift was the evident malfunction, the PCM will clear the SES after a few run cycles.

Also depends how long you disconnected the battery. Must be a minimum of 30 minutes.

Good luck,
Doug

Well, I unplugged the battery for 45 minutes and I still have the check engine light even though I have restored the skipshift to it's original state.

So, I tried cycling the engine (started and stopped) about 7 times and I still have the light.

Ugh. It looks like a trip to the dealer...

NORM: Thanks for your message. If I screw up again, I will now know to remove the PCM connections as well when trying to clear the check engine light.

Thanks again!
