I am new to the group. I have a 2010 Camaro 1SS 6MT with forged internals, 416 stroker kit, and LS9 blower on top.

Issue: When the car moves I get Service stabilitrack with all traction lights on. Sometimes I also get the BRAKE and ABS light on with them as well. It is usually a variation of 3 different lights that stay on at one time then go away.

I have been trying to diagnose my issue with stabilitrack and ABS for about a year now. I have replaced the hub and sensor and get proper readings on those from the scan tool. I also know it is not related to the engine. On the live data with the scan tool the ABS Pump Motor always reads 0V. The many codes I get are listed below and can also be found in the images. Thanks in advance any help would be great! I am desperate



I am thinking it is a problem with the ABS Pump and should be replaced or it is a ground somewhere. (Although I have looked so hard)

U0121 Lost communications with electronic brake control module (EBCM)

C0035 Left front wheel speed sensor circuit (even after replacing hub and sensor)

C0110 Pump motor circuit

C0242 Powertrain control module indicated traction control

C0245 Wheel speed sensor frequency

C0710-5A Steering position signal - Not plausible

U0125 Lost communications with multi-axis acceleration sensor module

U0126 Lost communications with multi-axis acceleration sensor module

U0121 Lost communications with electronic brake control module (EBCM)

Thanks!!!

I've seen this many times. It's usually the ebcm but I always sell the bpmv with it. Also looks like your going to need to replace the steering wheel angle sensor as well. The angle sensor is plug and play but the ebcm is not, it will need programming.
