If the Quick Test does not isolate the symptom, it will be necessary to check the operation of the Brake and Anti-Lock Warning Indicators. Observe the lamps and compare their on/off operation to the conditions listed on the chart. Once the actual warning indicator pattern has been matched to one of the conditions listed in the chart, perform the specific Pinpoint Test indicated.
