Final Procedure

  1. Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If any DTCs have not been diagnosed, go to DTC TEST and finish diagnosing remaining DTCs as necessary. If all DTCs have been diagnosed and repaired, go to next step.
  2. Connect scan tool to Data Link Connector (DLC) if not previously done. Ensure fuel tank is at least 1/4 full. Ensure A/C is off.
  3. Proper way to ensure DTC is properly repaired is to allow Powertrain Control Module (PCM) to run the monitor. Monitor operation may be observed on the scan tool. All specified enabling conditions for specified DTC must be met before PCM will operate the monitor.
  4. Using scan tool, monitor the pretest enabling conditions until all conditions have been met. Once all enabling conditions are met, observe appropriate monitor for DTC on the scan tool.
  5. If repaired DTC has reset or was seen in the monitor while on road test, repair is not complete. Check for related Technical Service Bulletins (TSBs) and return to DTC TEST, if necessary.
  6. If another DTC exists, return to DTC TEST and follow path specified by other DTC. If no other DTCs exist, repair is now complete.
