Having an issue chasing down why I’m unable to turn on traction control and stabilitrak. Use to come on every now and then but now it’s showing both off and not allowing me to turn on from the steering wheel. Checked ground under intake, wheel speed sensors and I just can’t seem to pin point what the issue is. Have two codes that popped up hoping someone can chime in and give me some kind of idea what the issue might be. Any help would be really appreciated

Have you had the interior apart recently? Or about the time you started noticing this issue?

The g-sensor on your dash gets its input from a gyroscope (Multi-axis Acceleration Sensor Module). The ECU or BCM (not sure which communicates with the module) has lost communication with this module. I do not know where it is located, but they are usually installed on the interior of the car.

I have, but my issue was a tone ring on a wheel bearing, different DTC. Yours is a different issue.

The sensor is located under the passenger seat, on the floorpan.
Relevant pages from FSM attached:
Font Paper Paper product Document Symmetry
Font Parallel Pattern Drawing Plan

Best of luck. Hopefully, it is just a loose connection.

I doubt it, but I can check the manual over the weekend.
To be honest, these modules, as a whole, rarely fail. I would bet you have a small wiring issue.
I had once pinched a wire so that the insulation was compromised and was shorting to ground. Fixed with a piece of electrical tape.

Cadillac mechanic seems to think it’s a wire or possible faulty EBCM. Will run through wires and see if anything’s pinched or broken then go from there I guess 🤷🏻‍♂️….
