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.
