This happens because there is a hard code stored in you computer in other words there is a problem like a bad 02 sensor or something like that. I recommend you take this car to an Auto Zone because they will check and tell you the codes for FREE. Or you can take to any auto place than can check codes. Then you can make the proper repairs and that WILL KEEP LIGHT OFF. If you reset with out making proper repairs it will only stay off temporarily and come back on like its been doing when you took off battery lead. Contact if you need more help. Good Luck

Wont stay running

When the SKIM key light on the instrument panel stays on as well, then its most probably a problem with a shorted PCI data bus. Fuel gauge, tacho meter and power windows also stop working then. Many times the problem is water ingress in connector C200 up in the passengers footwell area.

Check engine light is on my 2004 jeep grand cherokee laredo and is due to go in for emissions testing. It started after getting gas, then it would go off. Now it stays on constantly.

First check to make sure gas cap is on tight. (yes I know, sounds stupid but it's a possibility) If that doesn't cure light, stop into any good parts store like autozone, Advance, etc and have them do a FREE fault scan, they run the scan give you a print out and reset your lights. If light comes back on you HAVE an issue.

Are you using the seatbelts?
The airbag light is on because there is a problem with the system.
PLEASE do not try to fix the airbag problem yourself.
You could accidently activate the bag and get hurt.
