Clearing Codes

Using DRB-II, select test "ERASE FAULT DATA". Press "YES" key on DRB-II. DRB-II will display "ARE YOU SURE? YES/NO". Press "YES" key on tester. Tester will display "ERASING FAULT DATA X". When DRB-II is finished erasing fault codes, it will display "FAULT DATA ERASED".

If DRB-II is not available, fault codes may be cleared by allowing 50-100 key on/off cycles to occur. This will allow SMEC to clear fault codes.
