Diagnostic Trouble Codes (DTCS)

A diagnostic trouble code (DTC) is stored if the control module detects a fault. The driver information module (DIM) can store up to 10 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.
