Final Procedure

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.
NOTE: LDP DEALER TEST MODE is used when performing this test to verify repairs and check operation of the leak detection pump system. When performing this test, the operating mode of the Powertrain Control Module (PCM) will be changed. It is critical that the LDP dealer test mode must not be interrupted. If LDP dealer test mode is interrupted, the PCM will remain in the changed mode. This will cause the PCM to illuminate the MIL for 8-10 miles of driving and no DTCs will being stored in the PCM. Clearing the DTCs from the PCM will not change the MIL operation. If a vehicle is found with the PCM stuck in this changed mode, LDP dealer test should be performed in its entirety so proper PCM operating mode may be obtained.
Connect scan tool to Data Link Connector (DLC) if not previously done. Ensure all accessories are off. Start and allow engine to idle. Ensure shift lever is in Park and throttle is in idle position.
NOTE: Engine must remain at idle with shift lever in Park, and throttle at idle position when performing LDP dealer test. This test will only store a small leak DTC to indicate there is a problem with the system. The system failure may have been caused by a large leak, but the PCM will only set the small leak DTC to indicate that a failure occurred during the test.
Place scan tool in LDP DEALER TEST MODE and follow instructions as displayed on scan tool. If a DTC for a small leak is set, the repair is not complete. Check for related Technical Service Bulletins (TSBs) and return to DTC TEST, if necessary. If another DTC exists, return to DTC TEST and follow path specified by other DTC. If no other DTCs exist, repair is now complete.
