ERASE CODES

The Erase Codes function deletes DTCs from vehicle’s computer memory. It may also erase Freeze Frame, O2 Sensor Data, System Monitors, and On-Board Monitor test results. Perform this function only after systems have been checked completely and DTCs have been documented. This function should be performed with KOEO — Do not START engine.

After servicing vehicle, erase stored DTCs and verify no codes have been reset. If DTCs return, problem has not been fixed or other faults are present.

In addition to clearing DTCs, Erase Codes function may also erase Freeze Frame, O2 Sensor Data, System Monitors, and On-Board Monitor test results.
