Erase Codes
The Erase Codes function deletes the DTCs from the vehicle’s computer
memory. Perform this function with KOEO — Do not START engine. 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 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.
Select Erase Codes and press the
