Verification Tests —
POWERTRAIN VERIFICATION TEST VER - 6
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 diagnostic trouble codes are not repaired, go to symptom list and follow path
specified. After all diagnostic trouble codes have been repaired, return to TEST VER-6A and
run LDP Dealer Test Mode under Systems Test in DRBIII .
3. If the PCM was not replaced, skip steps 4 through 6 then continue with the verification.
4. 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.
5. In addition, start the vehicle 20 times after the module is replaced. After 20 starts, the new
PCM is in the proper in-field mode and will kill the fuel if it doesn't receive the VTA Status
J1850 message from the BCM.
6. For ABS and Airbag Systems: Enter correct VIN and Mileage in PCM. Erase codes in ABS
and Airbag modules.
7. The LDP Monitor Test Mode has been added to the DRBIII to verify repairs to the LDP
System. A DRBIII 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.
8. 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.
9. 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.
10. Erasing DTCs will not change this condition.
11. 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 can restore the PCM
operating mode.
12. Note similarity to LDP Monitor screen found under OBDII Monitors. Failure modes are
fewer in this System Test than OBDII LDP Monitor. System Test only stores Small Leak DTC
to indicate problem with system. No other type of failure mode indication given.
13. 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.
14. Connect the DRBIII to the data link connector. Engine running, turn off all accessories.
15. 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 in System Tests,
perform the LDP Monitor Test and follow the instructions on the screen.
Are any DTCs or symptoms remaining?
Yes → Check for any related Technical Service Bulletins and/or refer to the
apopropriate Symptom list (Diagnostic Procedure)
