Help In Diagnosing Airbag Light

[Jason in DLH]

Hi all! So my OBD scan tool is coming up with no codes regarding my airbag light and I’m finding myself wandering in the dark.

While replacing my steering wheel I swapped out the clock spring and airbag light is still on.

Any ideas would be greatly appreciated!

What type of scan tool are you using? Is it able to read SRS codes? Many of the lower end models only read DTC codes and not ABS or SRS codes.

 

[Jason in DLH]

I’m using the BlueDriver Bluetooth Pro OBDII Scanner which claims it can read the airbag sensor.

Are you using the BlueDriver app, or some other app?

 

[Jason in DLH]

I’m using the BlueDriver App which is great and even tells me I can check the airbag. I’ll be scanning one more time tonight, but I doubt it’ll catch anything.

 

[wjburken]

Might be worth a try to take it to Autozone and have them put their scanner on it and see what their scanner says.

 

[Jason in DLH]

I s’pose I should. I might buy stuff that I don’t need though.

I might buy stuff that I don’t need YET

FYP

 

[Jason in DLH]

True!

Most of the time it’s a cracked front impact sensor on these. If you Google it you can see there is an issue with the bolts being too tight and the sensors crack. Might just do a visual inspection of those sensors to see if they’re cracked. They’re mounted up behind the bumper.

I’ll check that out, thanks!

If the code points to the front impact sensor, this vid might be of interest:

Yep, if they’re cracked like that I would replace them both. I like how he mentions to not use Dorman parts. Not a place I would want to use Dorman.

 

[Fless]

Yeah, Eric's pretty firm against using Dorman whenever it's avoidable.

can't read srs or abs codes with the bluetooth adapters on these trucks, they wont do it, they will work on other vehicles just not these suv's, you need a wired obdii reader that will do abs/srs, it's a specific requirement, if you look on the box they usually have all the functions check marked on it depending on the model of the scanner.

Do they say on the box they won’t read abs or SRS on our trucks or do you have to find out the hard way?

I haven't seen one do it yet nor anyone else on here, there is a even a new fancy pants one on the market and I asked the seller if it would read it on our trucks and they said no,
I have 4 or 5 different bt ones and I tried all the apps out there and none will do it, they either hang, timeout or just simply won't read it.
on top of that abs and srs codes are not typical obd code's, they self check each time the key is cycled and if everything is good they wont light up or save a historical code, sometimes a abs or srs code will store but it depends on what the problem is, like when the abs modules get broken solder inside and when you hit a bump in the road it sets the abs light off and then when you park and take key out and then start it again the solder is connected and the code is gone because it passed self test.

most of the bt readers or any others for that matter will have a little disclaimer saying it may not read/work on all platforms yada yada.

So you’re saying you pretty much have to buy it and find out or ask the seller beforehand? You would think they would say they won’t work on certain vehicles.

most of them have a little disclaimer such as this one, and oddly enough almost all the bt readers out there are based on the same chipset, they just slap there own name on it.

Find someone with a tech 2 and have them scan your rig.
