APPLICABILITY

1. NOTE: After completing the Powertrain Verification Test the Transmission Verifi-
cation Test must be performed.
2. NOTE: If the PCM has been replaced and the correct VIN and mileage have not
been programmed, a DTC will be set in the ABS Module, Airbag Module and the
SKIM.
3. NOTE: If the vehicle is equipped with a Sentry Key Immobilizer System, Secret Key
data must be updated. Refer to the Service Information for the PCM, SKIM and the
Transponder (ignition key) for programming information.

complete. Check for TSBs that pertain to speed control problem and then, if necessary, return
to Symptom List.
8. Press and hold the RESUME/ACCEL Switch. If the vehicle speed did not increase by at least
2 mph, the repair is not complete. Check for TSBs that pertain to speed control problem and
then, if necessary, return to Symptom List.
9. Press and hold the COAST switch. The vehicle speed should decrease. If it did not decrease,
the repair is not complete. Check for TSBs that pertain to speed control problem and then, if
necessary, return to Symptom List.
10. Using caution, press and release the brake pedal. If the speed control did not disengage, the
repair is not complete. Check for TSBs that pertain to speed control problem and then, if
necessary, return to Symptom List.
11. Bring the vehicle speed back up to 35 MPH.

POWERTRAIN VERIFICATION TEST VER - 5- SBEC

APPLICABILITY

1. NOTE: If the PCM has been replaced and the correct VIN and mileage have not
been programmed, a DTC will be set in the ABS Module, Airbag Module and the
SKIM.
2. NOTE: If the vehicle is equipped with a Sentry Key Immobilizer System, Secret Key
data must be updated. Refer to the Service Information for the PCM, SKIM and the
Transponder (ignition key) for programming information.
3. Inspect the vehicle to ensure that all engine components are properly installed and
connected. Reassemble and reconnect components as necessary.
4. Connect the DRBIII

t to the data link connector.

5. Ensure the fuel tank has at least a quarter tank of fuel. Turn off all accessories.
6. If a Comprehensive Component DTC was repaired, perform steps 5 - 8. If a Major OBDII
Monitor DTC was repaired skip those steps and continue verification.
7. After the ignition has been off for at least 10 seconds, restart the vehicle and run 2 minutes.
8. If the Good Trip counter changed to one or more and there are no new DTC’s, the repair was
successful and is now complete. Erase DTC’s and disconnect the DRBIII

t.

9. If the repaired DTC has reset, the repair is not complete. Check for any related TSB’s or flash
updates and return to the Symptom list.
10. If another DTC has set, return to the Symptom List and follow the path specified for that
DTC.
11. With the DRBIII

t, 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).
12. If the monitor ran, and the Good Trip counter changed to one or more, the repair was
successful and is now complete. Erase DTC’s and disconnect the DRBIII

t.

13. If the repaired OBDII trouble code has reset or was seen in the monitor while on the road
test, the repair is not complete. Check for any related technical service bulletins or flash
updates and return to Symptom List.
14. If another DTC has set, return to the Symptom List and follow the path specified for that
DTC.

POWERTRAIN VERIFICATION TEST VER - 6 - SBEC

APPLICABILITY

1. NOTE: If the PCM has been replaced and the correct VIN and mileage have not
been programmed, a DTC will be set in the ABS Module, Airbag Module and the
SKIM.
2. NOTE: If the vehicle is equipped with a Sentry Key Immobilizer System, Secret Key
data must be updated. Refer to the Service Information for the PCM, SKIM and the
Transponder (ignition key) for programming information.
3. Inspect the vehicle to ensure that all engine components are properly installed and
connected. Reassemble and reconnect components as necessary.
4. The LDP Monitor Test Mode has been added to the DRBIII

t to verify repairs to the LDP

System. A DRBIII

t software program was written which causes the PCM to run the LDP

Monitor as part of this test. Test failures will be indicated through a stored DTC.
5. LDP Monitor Test Mode is a useful way to run a total system performance test. Use this test
to verify any type of LDP system repair.
6. Software program makes temporary changes to operating mode of PCM. For this reason, it
is critical that test not be interrupted. PCM’s left in this mode as result of interrupted test will
illuminate the MIL for 8-10 mi of driving with no DTC’s stored.
7. Erasing DTC’s will not change this condition.
8. If a vehicle is found to be stuck in the mode described above, the LDP Dealer Test should be
re-run in its entirety so that the software program in the DRBIII

t can restore the PCM

operating mode.
9. Note similarity to LDP Monitor screen found under OBDII Monitors. Failure modes are
fewer in this System Test than OBDII LDP Monitor.
10. System Test failure may have been, for example, due to a large leak, but the PCM will set
the Small Leak DTC to indicate failures that occurred as part of the system test.
11. Connect the DRBIII

t to the data link connector. Engine running, turn off all accessories.

12. Note: While test is being performed, PCM must see RPM, minimum MAP, No Vehicle speed
and minimum Throttle Position sensor (At idle, in park.) With DRBIII

t in System Tests,

perform the LDP Monitor Test and follow the manuals on the screen.
13. If the LDP Monitor Test failed and a .020 Leak DTC has set, the repair is not complete.
Check for any related Technical Service Bulletins and return to Symptom List.
14. If any other trouble code has set, return to Symptom List and follow the path specified for
that trouble code. If the LDP Monitor Test passed, the repair was successful and testing is now
complete.
Are any DTCs present?

All

Yes

→ Repair is not complete, refer to appropriate symptom.

No

→ Repair is complete.
