Hope it helps ya

I had the same problem in a way. My airbag light would come on and then go off. The airbag connections in the steering wheel got stuck somehow. It only can rotate lke 3 and 1/2 times and over the years mine just got stuck. (my yukon has over 200000 miles) All i did was press on the horn and wiggle the horn cover for about 20 seconds. I havent had a problem since.

SOURCE: service engine light staying on
Hello tdamm...No...the service engine soon (SES) light on your yukon is not telling you to change the oil.
This is a warning light that is illuminated when there is a problem affecting the Emission system and the engines computer management (ECM) has detected it from a fault. It could be something as simple as a loose or defective gas cap. If the SES light is blinking, it's more serious....
The yukon needs to be connected to diagnostic equipment (scanner) for fault diagnosis.
You can go to autozone they will hook up an OBD II scanner to your vehicle and explain the codes to you.
Good luck...i hope this helps and will fixya up.

One of your sensors are not working properly. It is still safe to drive. Have you bumped into something lately or had to jack the brakes? I know it's annoying but it will not go off on you.
