GM Service Manual Online
For 1990-2009 cars only

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 in Antilock Brakes for VES DTC diagnosis.
