31TH Transmission Verification Test

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2002 Dodge Grand Caravan, 2002 Dodge Caravan, 2002 Chrysler Voyager, 2002 Chrysler Town & Country, and 2001 Dodge Grand Caravan. However, it is still accessible from the selected car via links, so may be relevant.
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 Controller Anti-Lock Brake (CAB), Smart Key Immobilizer Module (SKIM), if equipped and Occupant Restraint Controller (ORC). 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 any DTCs have not been diagnosed, perform appropriate diagnostic test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . If all DTCs have been diagnosed and repaired, go to next step.
  2. 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 has been programmed, go to next step.
  3. Using scan tool, clear PCM and TCM DTCs. Ensure transmission fluid is at proper level. Ensure all accessories are off. Road test vehicle. Using scan tool, monitor engine RPM. Make 15-20 1st-2nd and 2nd-3rd 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. For a specific DTC, drive the vehicle to the Symptom's When Monitored/When Set conditions to verify the DTC repair. Check the DTCs during the road test. If a DTC resets, proceed to appropriate DTC test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . If no DTCs reset, repair was successful and test is now complete.
