Powertrain Verification Test VER-5

NOTE: For component location, see COMPONENT LOCATIONS  . For connector terminal identification, see CONNECTOR IDENTIFICATION  . For circuit identification and wiring diagram, see appropriate WIRING DIAGRAMS article.
  1. If the Powertrain Control Module (PCM) has been replaced and the correct vehicle mileage and Vehicle Identification Number (VIN) have not been programmed, a Diagnostic Trouble Code (DTC) will be set in Controller Anti-Lock Brake (CAB), Air Bag Control Module (ACM) and Sentry Key Immobilizer Module (SKIM). See POWERTRAIN CONTROL MODULE  under PROGRAMMING.
  2. If vehicle is equipped with SKIM, secret key data must be updated to enable engine starting. See SENTRY KEY IMMOBILIZER MODULE  under PROGRAMMING.
  3. Inspect vehicle to ensure all engine components are connected properly. Reassemble and reconnect components as necessary.
  4. Connect DRBIII(R) to data link connector.
  5. Ensure fuel tank is at least 1/4 full.
  6. If a Comprehensive Component DTC was repaired, perform steps  7 and  8 . If a major OBD-II Monitor DTC was repaired, go to step  9 .
  7. After the ignition has been off for at least 10 seconds, start engine and let it run for 2 minutes.
  8. If the Good Trip counter changed to one or more and there are no new DTCs, the repair was successful and is now complete. Erase DTCs and disconnect the DRBIII(R).
  9. If the repaired DTC has reset, the repair is not complete. Check for any related Technical Service Bulletin (TSB) or Flash Updates and return to DIAGNOSTIC TROUBLE CODE DEFINITIONS  .
  10. If another DTC has set, perform appropriate test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS  .

  12. If the monitor ran, and the Good Trip counter changed to one or more, the repair was successful and is now complete. Erase DTCs and disconnect the DRBIII(R).
  13. If the repaired OBD-II DTC has reset or was seen in the monitor while on the road test, the repair is not complete. Check for any related TSB or Flash Updates and return to DIAGNOSTIC TROUBLE CODE DEFINITIONS  .
  14. If another DTC has set, test is not complete. Are any DTCs present? If yes, perform appropriate test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS  . If no, repair is complete.
