Verification Test VER-5A - Road Test For OBD-II Trouble Codes

IMPORTANT NOTE: If the Powertrain Control Module (PCM) has been changed and the correct VIN and mileage have not been programmed, a Diagnostic Trouble Code (DTC) will be set in the ABS and Air bag modules. In addition, if the vehicle is equipped with a Smart Key Immobilizer Module (SKIM), Secret Key data must be updated to enable starting.

For ABS and Air Bag systems:

ACTION:
1. Enter correct VIN and Mileage in PCM.
2. Erase codes in ABS and Air Bag modules.

For SKIM theft alarm:

ACTION:
1. Connect the DRB to the data link connector.
2. Go to Engine, Misc. and place the SKIM in secured access mode, by using the appropriate PIN code for this vehicle.
3. Select Update the Secret Key data, data will be transferred from the SKIM to the PCM. Inspect the vehicle to ensure that all engine components are connected.

If there are any diagnostic trouble codes that have not been repaired, perform DTC TEST and follow the path specified. After all diagnostic trouble codes have been repaired, return to TEST VER-5A and run the appropriate monitor for the previously repaired OBDII trouble code.

1. Connect the DRB to the data link connector.
2. Ensure the fuel tank has at least a quarter tank of fuel.
3. Turn off all accessories.
4. The proper way to verify an OBDII Diagnostic Trouble Code repair is to allow the Powertrain Control Module (PCM) to run the appropriate monitor(s) and increment a global good trip. The technician can see the monitor using the DRBIII. The enabling conditions must be met before the PCM will run the monitor. Read the enabling conditions on the DRBIII monitor Pre-test screen.
5. With the DRBIII, monitor the pre-test enabling conditions until all conditions have been met. Once the enabling conditions have been met, monitor the appropriate OBDII monitor.
6. If the repaired OBDII trouble code has reset or was seen in the OBDII monitor while on the road test, the repair is not complete. Check for any technical service bulletins or flash updates and return to DTC TEST.
7. If another trouble code has set, return to DTC TEST and follow the path specified for that trouble code.
8. It the monitor ran, the good trip counter incremented and there are no new trouble codes, the repair was successful and is now complete.
9. Erase any diagnostic trouble codes.
