Clearing Diagnostic Trouble Codes

NOTE: This is the only information provided by the manufacturer for clearing diagnostic trouble codes for this system.

CAUTION:
1. If battery voltage is low, diagnostic trouble codes may not be output. Be sure to check the battery and charging system before continuing.
2. If the battery is disconnected or if the ECM (or PCM) connector connector is disconnected, the diagnostic trouble code memory will be erased. Do not disconnect the battery or ECM (or PCM) connector until after the diagnostic trouble codes are recorded.
3. Turn the ignition switch off before connecting or disconnecting the scan tool.

NOTE: If a DTC is erased, its "freeze frame" data will be also erased and the readiness test status will be reset. If necessary, take a note of the "freeze frame" data before erasing the DTC.




1. Connect the scan tool to the data link connector, and read the diagnostic trouble codes.
2. Repair the malfunction while referring to the INSPECTION CHART FOR DIAGNOSTIC TROUBLE CODES.
3. Turn the ignition switch to OFF and then back to ON again.
4. Erase the diagnostic trouble codes using the scan tool.
5. Confirm that the diagnostic trouble code reading is normal.
