Powertrain Verification Test VER-5

  1. Inspect the vehicle to ensure that all engine components are properly installed and connected. Reassemble and reconnect components as necessary.
  2. If any existing DTC's have not been repaired, go to the appropriate symptom test.
  3. Connect the DRBIII® to the data link connector.
  4. Ensure the fuel tank has at least a quarter tank of fuel. Turn off all accessories.
  5. If the PCM was not replaced, skip steps  68 and continue the verification.
  6. If the PCM was replaced, the correct VIN and mileage must be programmed or a DTC will set in the ABS and Air Bag modules. In addition, if the vehicle is equipped with Sentry Key Immobilizer Module (SKIM), Secret Key data must be updated to enable start.
  7. For ABS and Air Bag systems: Enter correct VIN and Mileage in PCM. Erase codes in ABS and Air Bag modules.
  8. For SKIM theft alarm: Connect DRBIII® to data link connector, Theft Alarm, SKIM, MISC. and place SKIM in secured access mode by using the appropriate PIN code for this vehicle. Select UPDATE SECRET KEY DATA. Data will be transferred from SKIM to PCM.
  9. If the catalyst was replaced, with the DRBIII® go to the MISCELLANEOUS Menu option "CATALYST REPLACED" and press enter.
  10. If a comprehensive component DTC was repaired, perform steps  1113 . If a major OBDII monitor DTC was repaired, skip step  11 and continue the verification.
  11. After the ignition has been off for at least 10 seconds, restart the vehicle and run 2 minutes.
  12. With the DRBIII®, monitor the appropriate pre-test enabling conditions until all conditions have been met. Once the conditions have been met, switch screen to the appropriate OBDII monitor (Audible beeps when the monitor is running).
  13. If the conditions cannot be duplicated, erase all DTC's with the DRBIII®. If the OBDII monitor test ran successfully and the Good Trip Counter changed to one or more, the repair is complete. If the test did not run successfully and the Good Trip Counter did not change to one or more, check for any related TSB's and/or see SYSTEM TESTS.
