Fault Code Definition

WARNING: This page is about a different car, the 1997 Mercedes-Benz E300. However, it is still accessible from the selected car via links, so may be relevant.

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.
