How do I erase diagnostic trouble codes from the vehicle's computer?

Press the ERASE button on the Scan Tool to erase DTCs and freeze frame data from the vehicle's computer and reset monitor status. However, before erasing codes, always consult the vehicle's service manual for proper testing procedures. DTCs will also be automatically erased after 40 warm-up cycles (80 for fuel and misfire faults) if the fault is not detected again during that period.
