HOW TO ERASE DTC
The diagnostic trouble code can be erased by CONSULT-II, GST or ECM DIAGNOSTIC TEST MODE as described in the following.
If the battery terminal is disconnected, the diagnostic trouble code will be lost within 24 hours.
When you erase the DTC, using CONSULT-II or GST is easier and quicker than switching the mode selector on the ECM.
