Diagnostic Aids

Using the failure records data may help locate an intermittent condition. If you cannot duplicate the DTC, the information in the failure records can help determine how many miles since the DTC set. The fail counter and pass counter can help determine how many ignition cycles that the diagnostic test reported a pass and/or a fail.

On vehicles equipped with a high pressure mechanical pump on direct injection engines, the vehicle may continue to run even though the pump in the fuel tank is not operating.
