Service Traction Light On,the Trac Off Light Too,the Abs And Brake Light Flashed A Couple Times Help

[maxwedge]

Needs to be scanned with an abs function scanner.

[richtazz]

sounds like a wheel speed sensor issue. If the wiring harnesses aren't corroded, an ABS capable scan tool will be needed to find out what wheel has the problem. It could also be the ABS module or pump.

SERVICE TRACTION SYSTEM
The IPC illuminates the SERVICE TRACTION SYSTEM indicator in the message center when the electronic brake control module (EBCM) detects a malfunction in the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination. The SERVICE TRACTION SYSTEM indicator illuminates for 60 seconds when the condition is present. The IPC sends a class 2 message to the radio in order to activate an audible warning.

TRAC OFF
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 body control module (BCM) detects that the traction control switch has been pressed (signal circuit is low). The BCM 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 BCM sends a class 2 message to the radio in order to activate an audible warning.
