One of two screens displays: If the diagnostic checks are working correctly and
no DTCs have been stored in vehicle’s memory, a SYSTEM PASS message

Erase Codes

The

Erase Codes

function deletes the DTCs from the vehicle’s computer mem-

ory. Perform this function with KOEO or KOER. This function should be per-
formed 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 will 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 tool
performs the appropriate

Erase Codes

procedure for your vehicle.
