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.
