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.
Circuit Description
The TRAC OFF indicator is controlled by the EBCM. The EBCM supplies the ground to the Trac Off indicator control circuit to turn the indicator on. When the Trac Off indicator control circuit is not grounded at the EBCM, the TRAC OFF indicator remains off. When the EBCM sees the traction control switch voltage go low, it turns the TRAC OFF indicator on and disables traction control.
