GM Service Manual Online

The scan tool, when plugged into the DLC, becomes part of the vehicle's electronic system. The scan tool can perform the following functions:

    • Display ABS and VES data.
    • Display and clear ABS and VES Diagnostic Trouble Codes (DTCs).
    • Provide diagnostic testing for intermittent conditions.

Verify the proper system operation and the absence of DTCs after completing the clearing procedure.

Refer to the Diagnostic System Check - ABS for VES DTC diagnosis.
