General Diagnostic Information

This information is necessary to diagnose the antilock brake system. Specifically, this section should be used to help diagnose conditions which result in any of the following:
1. amber ABS warning lamp turned on.
2. brakes lock-up on hard application.

Diagnosis of base brake conditions that are obviously mechanical in nature should be directed to Brakes, Testing and Inspection.

Many ABS conditions judged to be a problem by the driver may be normal operating conditions. See information in Description and Operation to become familiarized with the normal characteristics of this antilock brake system.
