Wierd Warning Lights

I'm new to the forum but it seems a lot of knowledgable people may be able to help me here.

A week ago my "change brake pads" warning came on. Went and checked my pads and they're like new.

Then my "airbag fault" came on. I'm positive I haven't been in a wreck.

Now they come on every time I start the car. Is there any help out there for how to clear these

warnings or what might be going wrong? I've heard I can disconnect the negative terminal on the

battery...but can't even find that. I know...I'm totally pathetic, but very appreciative of anyone who can help!

:welcome:

If the brake wear light comes on then the sensor for your pads need to be changed. It is just a special wire that when worn through turns on the light. So, if you did not replace the brake wear sensors then you need to.

There is at least two TSBs (Technical Service Bulletin) for airbag lights on MY03, 04, and MY05 Cayennes.

You should see your dealer and have them perform the procedure in TSB 9/04 6963 Airbag Warning Light On - Fault Code 1217 and 1218 -- dated Jun 7, 2005

Cayennes are very hard on batteries and they can cause loads of odd electrical problems. The main battery is located under the drivers seat on a l/hand drive vehicle. There is also a TSB for main wiring harness from the alternator to battery. Best take it in to the dealer and let them sort it.

P.S. It's also helpful to post the model year,engine size etc.
