Clearing Diagnostic Trouble Codes

Use a scan tool to clear DTCs from the PCM memory. Disconnecting the vehicle battery to clear the PCM memory is not recommended. This may not clear the PCM memory and other vehicle system memories will be cleared. Do not disconnect the PCM connectors solely for clearing DTCs. This unnecessarily disturbs the connections and may introduce a new problem. Before clearing DTCs the scan tool has the capability to save any data stored with the DTCs and then display that data at a later time. Capture DTC info before beginning diagnosis (refer to Capturing DTC Info). Do not clear DTCs until you are instructed to do so within a diagnostic procedure.
