Reading And Erasing Diagnostic Trouble Codes (DTCS)
Stored diagnostic trouble codes (DTCs) can be read off and erased using this function.
After the diagnostic trouble code (DTC) is stored it can also be read off if the fault is still present (permanent fault), or if the fault has disappeared for any reason (intermittent fault).
Diagnostic trouble codes (DTCs) can only be erased when all diagnostic trouble codes (DTCs) have been read at least once.
