Clearing Diagnostic Trouble Codes
- Ensure ignition is off. Connect scan tool to Data Link Connector (DLC). DLC is a 16-pin connector located below driver's side of instrument panel. See Figure .
- Turn ignition on. Using screen prompts on scan tool, clear DTC from Engine Control Module (ECM). Remove scan tool. Repeat vehicle drive cycle to ensure repair is complete and DTC is not reset. See VEHICLE DRIVE CYCLE under SELF-DIAGNOSTIC SYSTEM.
NOTE:
Engine Control Module (ECM) contains a readiness test status which will record whether a good or bad judgment has been made after the completion of a previous monitoring operation. This record may be read using the scan tool. When using scan tool, if the word COMPLETE is displayed, the judgement operation has been completed. The record will be reset if the battery is disconnected or if the DTC is erased from the ECM. If the record is reset, you will need to perform appropriate vehicle drive cycle once or twice in order to set the status back to COMPLETE for the following DTCs: P0130, P0135, P0136, P0141 P0400, P0420, P0442 and P0455.
