Diagnostic Trouble Codes (DTCS)

Diagnostic Trouble Codes (DTCs)

The control module will store a diagnostic trouble code (DTC) if it detects a fault. Up to model year 2000 inclusive the control module can store 20 diagnostic trouble codes (DTCs). From model year 2001 inclusive the control module can store 22 diagnostic trouble codes (DTCs).

If a fault disappears for any reason after the diagnostic trouble code (DTC) has been permanently stored in the control module, information about the fault remains in the control module.
