Fault Code Definition

After identifying malfunctioning component or system, see appropriate FAULT CODE DIAGNOSIS charts under DIAGNOSTIC TESTS .

Loose connections are stored if they occur several times over a certain time period. Fault codes caused by loose connections appear as stored fault codes and never as current fault codes.

NOTE: Generic scan tool will not identify all possible fault codes. It is recommended to use Hand Held Tester (HHT) for diagnosis.
NOTE: If no fault codes are displayed, there is no malfunction.
