Reading and Clearing Diagnostic Trouble Codes

Erasing diagnostic trouble codes

Stored diagnostic trouble codes (DTCs) can be read off and erased using this function. Diagnostic trouble codes (DTCs) can only be erased once all the diagnostic trouble codes (DTCs) have been read off at least once.
When erasing diagnostic trouble codes, the diagnostic trouble code's counter, status identifier as well as frozen values are also erased.
For certain systems, stored adaptions may also be reset when erasing.
