Here is a brief description of the indicator. If it is on at all times, there is more than likely a fault related. It would need scan tool diagnostics initially, to determine what the code is, and a course of action.
was turned to the ON position.
Enhanced Traction Control-TRAC OFF Indicator
The EBCM receives a Class 2 serial data message from the BCM indicating a traction switch activation. The EBCM determines the state of the TRAC OFF indicator and sends a Class 2 serial data message to the instrument cluster commanding the indicator state. The traction control switch is a momentary switch input into the BCM which detects the switch activation and sends the Class 2 serial data message. If an EBCM Class 2 failure occurs, the TRAC OFF indicator will not illuminate unless the indicator was illuminated prior to the Class 2 failure.
This is a brief description of the message. More than likely it has come on relating to a fault that would inhibit traction control. It should have stored a fault code that would determine a course of action.
