Diagnostic Trouble Codes (DTCS)

If the control module detects a fault then it stores a diagnostic trouble code. If a fault disappears for any reason after a diagnostic trouble code has been permanently stored in the control module then the information on the diagnostic trouble code remains in the control module in a number of driving cycles that can be calibrated.
