2011 tahoe driver front door replaced, and now an SRS driver door service air bag code

tgwhit12 · Apr 26, 2026

Guys, I’m at my wits end. If you have any experience with an issue like this, please tell me what to do.

2011 tahoe driver front door replaced. Now i get a code SRS driver door service air bag. I change the door harnes. The SRS driver door light still comes on followed by "Driver door not shut" and my cabin lights are now on too. i change the door actuator, reassemble everything, and get "Service Air Bag". DTC says driver front SRS high resistance I driver door. Also still get "Driver Door Open", and my dome lights are still on. I drive it hoping it will cycle, bit then my "Service Tire Pressure Monitor System.
So now I’ve tried two different door harnesses, two different door actuators, and I just bought new GM, tpms sensors, but I’m not going to put them in until this is figured out.
Please help if you can.

A big help would be to put a good bidirectional scanner on it and get the specific codes that are being thrown by the modules. Post them here and we can see if we have any suggestions.

I bought an Innova 5610 to try and clear the codes. I spent some time this evening working on it before supper.
It will erase the SRS code DTC, but it come a right back.
I’ll get the specifics tomorrow.
Thank you.

SRS codes are hard faults and codes won't go away until the cause is fixed.

Why did you replace the door?

Can't you just put a piece of tape over them?

there is a srs sensor in the door, I would suggest checking that versus replacing harness

The long of it is, I bought it cheaper because as a cop car it was black, but had white doors. I did a cheap paint job to convert that. About 4-5 months ago, I was parked at Best Buy, came out and a woman had run into my pass front door(she ran and couldn’t get tag number on video). Bought replacement salvage yard doors that honestly looked way better than painted doors. Replaced pass door and forgot to replace door sensor - code. Changed to old sensor (had to spice wires, but code went away).
The driver door looked better too, so I was trying to improve the truck.

I used the original sensor from my door. A mistake I may have made is I didn’t change the door wiring harness originally. I sliced the wires. When I got the code, because the plugs are different. I thought the splice might be the problem, so I changed the door harness and soldered them together and tried again. Still all the codes I mentioned. I don’t know.

Fless · Apr 29, 2026

I haven't seen any specific codes mentioned, or did I miss those?

mikez71 · Apr 29, 2026

What part of the harness are you splicing? If splices are in door, perhaps it's the wiring in the door boot..

sounds like you used a door from a different year or model????
double check your work.
you might need the right sensor, some may have different ohm readings, hence the connector change.

Fless · Apr 29, 2026

SRS circuits are very reliant on tight ohm tolerances. Splices may impact the ohm value.

I used the original sensor in the door that’s kicking the code. At first, I didn’t want to pull the entire wire harness, and the male plug was different from the female on the sensor itself, which is why I spliced the wires. After the code, i
Changed the entire harness from the original door, but I’d already spliced the wires for the replacement door harness. That’s why I went back and soldered the wires after the code. That’s the only thing I could think of causing the problems.
I’d previously spliced the passenger door, the one the lady hit and that code went away.

I spiced the door impact sensor wires about 4” before the sensor.

mikez71 · Apr 30, 2026

Since you used the harness that came on the replacement door, possible it is damaged?

You could unplug the harness inside cabin and ohm the wires to the connectors inside the door. Then you'll know if it's wiring or not..

You could also measure the resistance of the passenger door sensor and compare to the driver door sensor.

The door latch ajar/open signals apparently go to the driver door module, which is networked with other modules.

dkad260 · Apr 30, 2026

Does the door close normally, with no hangups, any signs of a rough latching mechanism...basically mimic the other doors? The latch may not be fully closing and/or just the sensor tripping both codes thinking it is open.

I get a random "Service Airbag" on my DIC, and it shows incorrect resistance and points to the clock spring. However it's just a loose connection in the 4-pin harness near the kick panel. A quick wiggle and it goes away, I am going to tighten up the female pins to hopefully fix this.

dkad260 · Apr 30, 2026

It was this connector here that had me taking my steering wheel apart until I realized what it was.

Reason i'm posting this is to check the connections underneath the kick panel as well or anything you may have disturbed.

tgwhit12 · Apr 30, 2026

dkad, I think you’re on to something. AI said something similar. Since I’ve tried two different door harnesses, I feel like it’s not a cracked wire. It either has to be the splice or another connector away from the harnesses.
Just no way both harnesses are bad, especially when one was perfect before I replaced the door.
I feel like the splice job on the door sensor with the splicing and soldered connection is far superior to what I did on the passenger door and it worked there.
I think it has to be a connector. The pic you’re showing, is
That the fale
That’s behind the kick panel? If so, would bent or bad pins also affect the door lock reading? Someone asked above, but this door is superior in fit and sound deadening than the original cop door. I think those hinges were slightly sprung.
Thanks for the reply.

On mine it's visible looking above the parking brake.

I'm not sure if it incorporates wires for the door
