Diagnostic Trouble Codes (DTCS)

A diagnostic trouble code (DTC) is stored if the control module detects a fault. The control module can store up to 20 diagnostic trouble codes (DTCs).

Should a fault disappear for any reason after being stored in the control module as a diagnostic trouble code (DTC), the information remains stored in the control module. If a fault is no longer permanent, the diagnostic trouble code (DTC) remains as intermittent.
