Verification Tests
VERIFICATION TEST VER-1A APPLICABILITY
No Start Verification
Use this test to verify that a No Start condition has been repaired and that the vehicle can be
returned to the customer.
Note: If the Powertrain Control Module has been replaced and the correct VIN and
mileage have not been programmed, a DTC will be set in the ABS, Airbag and the
SKIM modules. In addition, if the vehicle is equipped with a Sentry Key Immobilizer
Module (SKIM), Secret Key data must be updated to enable starting. Refer to
GENERAL INFORMATION section for programming information for the PCM, SKIM
and the Transponder (ignition key).
1. Inspect the vehicle to ensure that all components related to the repair are connected
properly.
2. Inspect the engine oil for fuel contamination. Replace the oil and filter as necessary
3. Attempt to start the engine.
4. If the No Start condition is still present, refer to the symptom list and perform diagnostic
testing as necessary. Refer to any Technical Service Bulletins that may apply.
5. Run the engine for one warm-up cycle to verify proper operation. With the DRBIIIt, confirm
that no DTC's are present and that all components are functioning properly.
6. If DTC's are present, refer to the symptom list and perform diagnostic testing as necessary.ALL
VERIFICATION TEST VER-2A APPLICABILITY
Non-OBDII Verification
Use this test to verify that a non-OBDII symptom has been repaired and that the vehicle can
be returned to the customer. A non-OBDII symptom is a comprehensive component related
symptom that is not the result of a failed OBDII major monitor.
Note: If the Powertrain Control Module has been replaced and the correct VIN and
mileage have not been programmed, a DTC will be set in the ABS, Airbag and the
SKIM modules. In addition, if the vehicle is equipped with a Sentry Key Immobilizer
Module (SKIM), Secret Key data must be updated to enable starting. Refer to
GENERAL INFORMATION section for programming information for the PCM, SKIM
and the Transponder (ignition key).
1. Inspect the vehicle to ensure that all components related to the repair are connected
properly.
2. With the DRBIIIt, Clear DTC's and Reset Memory (all engine values).
3. Run the engine for one warm-up cycle to verify proper operation.
4. Road test the vehicle. Use all accessories that may be related to this repair.
With the DRBIIIt, confirm that no DTC's are present and that all components are functioning
properly.
6. If this test is being performed after a No Trouble Code test, verify that the symptom is no
longer present. If the symptom is still present, or any other symptom or DTC is present, refer
to the symptom list for further diagnostic testing procedures. Check for any Technical Service
Bulletins that may apply.
7. If there are no DTC's present and all components are functioning properly, repair is
complete.ALL

VERIFICATION TEST VER-3A APPLICABILITY
Charging System Verification
Use this test to verify that the Charging System symptom has been repaired and that the
vehicle can be returned to the customer.
Note: If the Powertrain Control Module has been replaced and the correct VIN and
mileage have not been programmed, a DTC will be set in the ABS, Airbag and the
SKIM modules. In addition, if the vehicle is equipped with a Sentry Key Immobilizer
Module (SKIM), Secret Key data must be updated to enable starting. Refer to
GENERAL INFORMATION section for programming information for the PCM, SKIM
and the Transponder (ignition key).
1. Inspect the vehicle to ensure that all components related to the repair are connected
properly.
2. With the DRBIIIt, Clear DTC's.
3. Perform generator output test. Refer to the appropriate service information as necessary.
4. Start the engine and set engine speed to 2000 RPM for at least thirty seconds.
5. Turn the ignition OFF.
6. Turn the ignition ON, with the engine not running.
7. With the DRBIIIt, Read the DTC's. If the DTC returns, or any other symptom or DTC is
present, refer to the symptom list for further diagnostic testing procedures. Check for any
Technical Service Bulletins that may apply.
8. If there are no DTC's present and all components are functioning properly, the repair is
complete.All
