Erase Codes
✓
The Erase Codes function deletes the DTCs from the vehicle’s
computer memory. Perform this function with KOEO or KOER.
This function should be performed only after the systems have
been checked completely and DTCs have been documented.
✓
After servicing the vehicle, erase the stored DTCs, perform a road
test, and then verify no new codes have been stored. If DTCs
return, the problem has not been corrected or other faults are
present.
✓
Some codes can only be removed by repairing the faults that
caused them. Therefore, these codes remain in the vehicle’s
memory until the condition is repaired.
✓
Not all trouble codes can be automatically erased using the Scan
Tool. Some vehicles require a manual erasing procedure. If
possible, the Scan Tool performs the appropriate Erase Codes
procedure for your vehicle.
