Test VER-6

NOTE: If replacing Powertrain Control Module (PCM), the correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into PCM to prevent Diagnostic Trouble Codes (DTC) from being stored in Anti-Lock Brake System (ABS) module and Air Bag Control Module (ACM). If replacing PCM and vehicle is equipped with a Smart Key Immobilizer Module (SKIM), secret key data must also be updated to enable engine starting.
  1. Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If repair procedure did not include replacing PCM, go to next step. If PCM has been replaced and has already been programmed, go to next step. If PCM has been replaced but has not been programmed, program PCM and clear DTCs. See PROGRAMMING . After PCM is programmed, go to next step.
  2. If any DTCs have not been diagnosed, perform appropriate diagnostic test. Return to DTC MESSAGES & CODES  table under DIAGNOSTIC CODE DEFINITIONS. If all DTCs have been diagnosed and repaired, go to next step.
    3. 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 system. System failure may have been caused by a large leak, but PCM will only set small leak DTC to indicate that a failure occurred during test.
    NOTE: LDP DEALER TEST MODE is used when performing this test to verify repairs and check operation of leak detection pump system. When performing this test, operating mode of Powertrain Control Module (PCM) will be changed. It is critical that LDP dealer test mode not be interrupted. If LDP dealer test mode is interrupted, PCM will remain in changed mode. This will cause PCM to illuminate MIL for 8-10 miles of driving and no DTCs will be stored in PCM. Clearing DTCs from PCM will not change MIL operation. If a vehicle is found with PCM stuck in this changed mode, LDP dealer test should be performed in its entirety so proper PCM operating mode may be obtained.
  3. Connect scan tool to Data Link Connector (DLC), if not previously done. Ensure all accessories are off. Start engine and allow it to idle. Ensure shift lever is in Park and throttle is in idle position. 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, repair is not complete. Check for related technical service bulletins and return to diagnostic test from which you came. If any other DTC exists, perform appropriate diagnostic test(s). See DTC MESSAGES & CODES  table under DIAGNOSTIC TROUBLE CODE DEFINITIONS. If all DTCs have been diagnosed and repaired, test is complete.
