Occasionally my traction off light comes on, but there is no change in how the transmission performs it shifts and runs like a new car.

Good morning.

Do you have a scan tool to access the ABS system to check for any stored codes? It is part of the ABS system.

I see you are listed as a mechanic. Is the ABS light coming on as well?

LOW TRACTION
The IPC illuminates the low traction indicator when the following occurs:
The Electronic Brake Control Module (EBCM) detects a traction control event. The IPC receives a class 2 message from the EBCM requesting illumination.
The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.

TRACTION OFF
The IPC illuminates the traction off indicator when the following occurs:
The electronic brake control module (EBCM) inhibits the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination. The traction control system is disabled when the following occurs:
- (Chevrolet Only) The shift lever is in FIRST (1) or SECOND (2) gear. The EBCM receives a class 2 message from the powertrain control module (PCM) indicating the gear position.
- (Pontiac and Oldsmobile Only) The Body Control Module (BCM) detects that the traction control switch is pressed (signal circuit is low). The EBCM receives a class 2 message from the BCM indicating the switch status.
- The BCM detects that the park brake is engaged (signal circuit is low) and that the engine is on. The EBCM receives a class 2 message from the BCM indicating the park brake status.
- The PCM detects certain malfunctions and is unable to perform torque reduction requests from the EBCM. The EBCM receives a class 2 message from the PCM indicating that traction control cannot be performed.
The EBCM detects a malfunction in the traction control system. The IPC receives class 2 messages from the EBCM requesting illumination of both the service vehicle soon and traction off indicators.
The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately three seconds.
