Clearing Diagnostic Trouble Codes

ALL MODELS

To clear the diagnostic trouble codes from the computer's memory, do the following procedure:

1. Turn the ignition OFF.
2. After removing the battery cable from the battery terminals for 10 seconds or more, reconnect the cable.
3. Turn the ignition ON and take a reading of the diagnostic output to check if a normal code is output.
4. Let the engine warm up and then run it at idle for about 10 minutes. Recheck for any diagnostic codes.
