Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Aids
The following conditions may cause an intermittent:
- Intermittent short to ground in Brown/White wire between BCM and TCS switch.
- TCS switch sticking or internally shorted to ground.
- TCS switch is pressed for longer than 60 seconds.
If Brown/White wire between BCM and TCS switch is shorted to ground, TCS will stay on or off at all times depending on which state it was in when malfunction occurred. If short to ground occurred when TCS was on, TCS will remain off at all times. If short to ground occurred when TCS was off, TCS will remain on at all times. BCM will retain this information even if ignition is turned off.
