Default Service Brake Assist/ traction control

Soo... For some reason the last week I've gotten, Service Traction Control, and Service Brake Assist to come up on the DIC. I'm also getting strange TPMS readings, 7 PSI one day, and 60PSI the next. The battery is a year old and I cleaned the terminals and cables when I started having the issue.

BCM, ECM issue?

Scheduled to take it to the dealer on Tuesday. :-(

I figured it out! :-)

Had time to poke around today. I grabbed the R/F ABS sensor wires and moved em around. It made the ABS lights go crazy, I pulled it apart to find a broken wire where the wires make a 90 degree bend. Clipped, and spliced back together, no issue now.

It's amazing that one sensor controls the ABS, traction control and TPMS.

Thanks for the help!!

LOL you will be suprised what will cause the ABS, TC, StabiliTrac, ect go off in the cars. There are tons of sensor all connected through the BCM. Yaw, Steering, brake pedal position, ABS, ect.
