06 GMC Sierra 1500 not HD, not sure on mileage or steering wheel controls.

Going to be looking at a 06 GMC Sierra. Don't know if it has radio controls on steering wheel and what else.

I Do know what the owner told me. HE had it at the dealer and they said it needed a clock spring but told him they don't like to work on the older vehicles.

This came up after he realized that I Do work for people I know, friends and the like. He's been a neighbor for probably eight to 10 years.

He asked me if I knew how to change the clock spring and I told him that shouldn't be much to it as I'm comfortable around airbag systems as I've worked on my wife's Chevy Impala the airbag system and that was before I signed up for Mitchell DIY and before I'd watched Paul's video on the Chevy Tahoe I believe it was he did that they replaced the front impact sensors due to corrosion or failure of the plastic but there was a video I watched where Paul fixed it.

Back to the sierra. Don't know mileage.

He did say that the brake light in the dash came on along with one other or so things.

He also stated that if they cleared the airbag code when the vehicle was put back online only the airbag code would come up and the brake light in the dash wouldn't come back on till later so that makes me suspect a separate issue, possible brake shoes for the parking brake? Would they have sensors back then for those or not?

One other thing that came to mine is possibly with the clock spring that the wiring that goes through there with the clock spring being Warren maybe some of that wiring for the dash light is also tied in there as there are several wires that hook into that clockspring as I watched a few videos.

I've definitely plan on hooking up both of my upper end scan tools to see what I can pull for codes.

My question is am I thinking improperly about the parking brake light in the dash? IS there generally any correlation between air bag code and brake light in dash?

Wonder why the dealer didn't want to work on this or so he said. Maybe the quote to repair was to high but we agreed on a rate

He's also made me a offer on a storage space of 20 x 40 for automotive repair but I don't like that there's no water, sewer, etc I'd rather have a 40 x 40 as I think I could get a few hoists in there with future expansion as I grew for things such as a alignment rack plus my concern would be the electrical grid as I'd want power. I doubt think we're at that point though so ill push ahead with my oversize and extra deep 3rd stall this summer

Anyways back to the sierra. It also has crew cab 4 door as well.

Ill definitely Do the proper diag on the part as I don't want to get burned on a part which is upper $100 just below $200 ish range. It's not only that but the safety aspect and I always want to be right on point and nothing less.

Any pointers, tips, safe tricks, etc that I could use for checking things out?

I did buy a AES wave wire kit awhile back as Paul has, yeah we all want to be like Paul but we'll get close and always just be ourselves. Anyways I recall that kit having some ABS test parts in there as I wasn't much into ABS then when I purchased it. IF anyone knows how to use those adapters m, how they work, etc I am all ears

I know how to take SRS offline from the control modules as I had to remove passenger seat in the wife's impala and sensors and test wiring with my short detector from the power probe short kit and remove the control module in the floor pan below the seat.

Just trying to think of and bring anything possible up that may need to be covered
.I checked the archives and saw more of Ford and Andy was in on those responses.

Thanks in advance for any and all suggestions, tips, tricks, help, knowledge, etc.

I will have another post about a heated seat shortly as well. Same owner. HE has multiple trucks

I've never done a clockspring on one of these trucks, so I don't have much for you on that one. :silly:

The brake warning light on could be a couple different things. There's no sensors at the parking shoes, directly, just the switch on the parking brake pedal. The brake fluid level sensor is another. The brake switch (on the service brake pedal, not the parking brake) commonly goes bad, but almost always has a P0571 or P0572 stored.

Okay ............... at Key On the SRS module does two different kinds of checks.

The air bags and the wiring to them including the clock spring are checked by a simple continuity ressistance check.

However the impact sensors are smart sensors and the SRS module looks for a specific response from each sensor. Paul pretty well nailed impact sensors in his video, water ingress is the most common cause of wear and tear failure of these impact sensor even on the ones that are mounted inside the car,

Where a fault code points to an individual air bag it is usually wiring or connector issue, with steering wheel air bags it willl often be either the clock spring or the wiring harness that runs up the steering column.

However with side impact air bags often just cleaning or wiggling the under seat connectors is enough extingish the SRS warning light at least in the short term, but it will usually reoccur next time the seat postion adjustment is moved.

If you have a code pointing to an individual air bag it is usually a simple matter of wiring integrity ressistance checks and visual checks or trying a substitute resistor.

As for the brake warning light it could simply be low fluid level or a fault with the fluid level switch or a pad wear indicator or the switch on the handbrake lever. The ABS system usually has a separate warning light.
