2003 CTS Airbag Light and the Stereo ??

aK47 · #1 (**permalink**) 04-05-08, 03:43 AM

I have a 2003 CTS. A while ago the airbag light came on. It doesn't always come on(most of the time though) but when it does it also interferes with the stereo system. I believe the speakers because the song will continue playing but the speakers cut out for a time.. This happens when playing a cd or the radio.
I took the car to both a private shop and also a Cadillac dealer. Both hooked the car to the computer and saw no errors..

Any ideas??

I get the airbag light intermittently, there is a plug under the passenger seat, I unplug it and reseat it that seems to fix it every time. It happens about 3 times a year.

Thanks for the reply samd and I am fine with doing that... Where under the passenger seat is it? I thought it would be under the rear bench seat where the fuse box is... Can you point out more specifically where this plug is??

Thanks so much!

Under the front part of the passenger seat there is a yellow plug. Disconnect it and reconnect it. That should fix it. Note: it may be different for different years, mine is an 03 with a manual passenger front seat. The plug is yellow for the air bag sensor.

It's not a great picture but it's on the front passanger side near the front of the seat.

hey there im new to this site just bought a 2003 cadillac cts 3 months ago and i seem to have a problem with the airbag light indication on my dash always being on, also when i pull up the codes i get 2 that can not be reset (ipc u1000 and irc u1000) i dont know if they have anything to do with the airbag.
every time i get in my car and start the engine or have it on the on possition the air bag light flashes 6 times but instead of going off and just having the seatbelt light on the seatbelt light goes off and the airbag light stays on though out my driving, i have noticed that if i play with the stering wheel before i start the car or having it on the on possition that sometimes i will go off! and i am able to clear those 2 codes mentioned above. but im not really sure if that might be the cause.
any help would be appriciated
thanks in advance

I have an 03 as well. u1000 is Class 2 communication malfunction. I get it all the time, when I reset it, it comes right back. I don't think it causes any problems.

Reseat the yellow connectors under both front seats. That shoud resolve the Air-bag light.

nope it resolved nothing i unpluged both D and P and still the same unless im doing something wrong there that did not fix the problem

when you say reset do you mean unplug and plug back? should the keys be in ON mode or the car on?

No, I did mine with the power off. I unplugged it, then pushed the plug back together. That seemed to fix it. When I started it back up the light was off. Sorry I couln't help you.

my airbag light IS GONE thanks for your help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I read more where that connector goes to the side curtain airbag and there are know problems with the connectors. My car is out of warranty so I'm sure the dealer won't fix it free. I just reseat that connector whenever the light goes on and it seems to do the trick.

Everytime you start your car the airbag system does a self test to make sure it is in working order. If it fails for any reason the light comes on to tell you that you are not protected in the event of a crash.

please please please!! dont do that!!! the yellow connector under the seat is for your pretensioner and the connector has a shorting bar in it, damaging that connector could lead to unwanted deployment. the module for the air bag is under the center console. if you are playing with any connector PULL THE FUSE FIRST! ive seen too many accidental deployments from factory techs . on another note if your air bag light comes on there is a problem, if it has a u1000 in the sdm or a light with no codes chances are its a problem with the sdm

Thanks, where is the fuse for the Air Bag? Do you know if the airbags are warrantied for life?

cadillacroadside · #15 (**permalink**) 05-13-08, 10:59 AM

im sorry to say the air bags are not warrantied for life (tho they should have a much longer warranty imo). one thing i would like to say about these forums is i see alot of people here that have ALOT of cadillac knowledge that are not proffesional technicians and offer alot of help, unfortunetly when it comes to playing with an air bag system doing the wrong thing can lead to tragedy, ive seen disasters at the hands of professionals that deal with it on a daily basis, ive been with caddy for 22 years and seen over a handful of deployments with injury and its not pleasant. i jumped into this post to advise people excercise the greatest of caution when they do any work on the sir system. first and foremost is safety and i strongly encourage that to my techs as well
