Erase Codes

The Erase Codes function deletes the DTCs from the vehicle's computer
4
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
(17(5 key.
A message appears asking if you are
sure. Press /()75,*+7 to move the
brackets to the desired response and
press (17(5.
Selecting NO and pressing (17(5
returns you to the GM Function List.
