Quick Tests

Fig. 84 Diagnostic Warning Lamp Symptom Chart:

If quick test checks and anti-lock quick check sheet procedure does not isolate the symptom, it will be necessary to check operation of the brake and anti-lock warning lamps. Observe lamps and compare their ON/OFF operation to conditions listed in the Diagnostic Warning Lamp Symptom Chart. Once actual warning lamp pattern has been matched to one of conditions listed in chart, perform the specific Pinpoint Test diagnostic procedure.
