Diagnostic Trouble Codes (DTCS)

If the control module detects a fault then it stores a diagnostic trouble code (DTC). If a fault disappears for any reason after a diagnostic trouble code (DTC) has been permanently stored in the control module then the information on the diagnostic trouble code (DTC) remains in the control module.
