TRAC Off
WARNING: This page is about a different car, the 2007 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The IPC illuminates the TRAC OFF indicator when the following occurs:
- The electronic brake control module (EBCM) inhibits the traction control system due to a malfunction in the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination.
- The rear integration module (RIM) detects that the traction control switch has been pressed (signal circuit is low). The RIM sends a class 2 message to the EBCM in order to disable traction control. The IPC receives a class 2 message from the EBCM requesting illumination. The RIM sends a class 2 message to the radio in order to activate an audible warning.
