Diagnostic Process
Perform the following steps in order when servicing the ABS/EBD system. Failure to do so may result in the loss of important diagnostic data and may lead to difficulties and time-consuming diagnosis procedures.
- Perform the tests of the table below.
- Perform a road test if directed by the table.
- Test drive the vehicle while using the snapshot feature of the scan tool.
- Perform normal acceleration, stopping, and turning maneuvers.
- If this does not reproduce the malfunction, perform an ABS stop on a low friction surface such as gravel.
- Clear the diagnostic trouble codes (DTCs) after all system malfunctions have been corrected.
