Abs/traction control

[kbuskill]

I get the same results I get with the torque app, it tries to communicate with the abs/srs module gets to about 98% then craps out and fails to communicate, it shouldn't do that it should communicate and say no codes are present just like a wired scanner would. There is some other new fancy bluetooth tool out that is supposed to read abs/srs and a bunch of other stuff I contacted them to confirm and they replied saying the tool wont work for abs/srs with my truck via bluetooth either.

Was that on the Denali or your new pickup?

get the same result either one, srs/abs is a standard like obd 96-2021 should give the same codes at least I think so

just went out and tried it on the ol'ladys 04 burb because it has a airbag error and same result gets to 98% and disconnects, she was in a accident a couple years ago I repaired everything except pulling the abs module to get it wiped so it has a open code, the only thing that will pull the code is a tech2 or a wired scanner that reads abs/srs

Bosch sell its App in google store for $30, including reading all makers' ABS code

they all say they work but I have yet to see one pull srs/abs codes from a gm suv via bluetooth, can't even find a video showing one doing it on a gm, ford yes, other makes models yes, gm suv/pickup nope.

Guess I'm either lucky or crazy... not sure which at this point... lol

Maybe I will have to go out and plug into the Burb and find out which it is.


*** EDIT ***

So I just went out and hooked up my Bluetooth OBD2 adapter to check and see if I was crazy.

I guess I'm only half crazy...

I couldn't get it to read the SRS module... seems like I tried this before and it worked but maybe not.



It does however read the ABS module without any issue.

Turns out I have 2 codes that I was unaware of, because there is no ABS light on.



I also snapped a pic showing the protocol that it uses to connect to my truck... CAN 500k Type 1...



It also connected to the TCM as well without any problem...



So what does all this mean?... I have no idea... but it seems to work on my '08 Suburban just fine.

if it works then show me what adapter you are using

Not sure if you saw my edit above.

This is the adapter I use...

Vgate iCar 2 Bluetooth OBD2 Scanner | OBD Innovations
https://www.obdinnovations.com/vgate-icar-2-elm327-bluetooth-obd2-scanner-with-auto-sleep/

Their website says...

• Compatible with SAE J1850 PWM and SAE J1850VPW protocols found on many Ford and GM vehicles (these protocols are NOT supported on cheaper bluetooth scanners)

Not sure if that makes a difference.

Well apparently these abs modules are different and cannot be repaired like the other ones. The non Denali can be repaired. So now I have to order a new one. Do these need programmed after install? If so is it at least drivable to dealer for a program?
