Aw4 Trans Verification Test

NOTE: If replacing Powertrain Control Module (PCM), 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 Sentry 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 any DTCs have not been diagnosed, perform appropriate diagnostic test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS  table under SELF-DIAGNOSTIC SYSTEM. If all DTCs have been diagnosed and repaired, go to next step.
  2. If repair procedure did not include replacing Powertrain Control Module (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.
  3. Using scan tool, clear PCM and Transmission Control Module (TCM) DTCs. Ensure transmission fluid is at proper level. Road test vehicle. Using scan tool, monitor engine RPM. Make 15-20 1st-2nd, 2nd-3rd and 3rd-4th upshifts. Perform shifts from a standing start to 45 MPH with a constant throttle opening of 20-25 degrees.
  4. With vehicle speed less than 25 MPH, make 5-8 wide open throttle kickdowns to 1st gear. Allow at least 5 seconds each in 2nd and 3rd gear between each kickdown.
  5. Using scan tool, monitor SIMILAR CONDITIONS and attempt to duplicate conditions that vehicle was operating at when DTC was set. If conditions can be duplicated, GOOD TRIP counter will change to one or more. If repaired DTC resets, proceed to appropriate DTC test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS  table under SELF-DIAGNOSTIC SYSTEM. If conditions cannot be duplicated and GOOD TRIP counter changed to one or more, repair was successful and test is now complete.
