Powertrain Verification Test VER-6

NOTE: If replacing Powertrain Control Module (PCM), the correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into PCM to prevent Diagnostic Trouble Codes (DTC) from being stored in Controller Anti-Lock Brake (CAB) module, Air Bag Control Module (ACM) and Sentry Key Immobilizer Module (SKIM). If replacing PCM and vehicle is equipped with SKIM, secret key data must also be updated to enable engine starting. See PROGRAMMING .
  1. Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If repair procedure did not include replacing PCM, go to next step. If PCM has been replaced and has already been programmed, go to next step. If PCM has been replaced but has not been programmed, program PCM and clear DTCs. See PROGRAMMING . After PCM has been programmed, go to next step.
  2. Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If any DTCs have not been diagnosed, perform appropriate diagnostic test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . If all DTCs have been diagnosed and repaired, go to next step.
  3. 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. Go to next step.
  4. 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. Go to next step.
  5. 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 miles of driving with no DTCs stored. Erasing DTCs will not change this condition. Go to next step.
  6. If a vehicle is found to be stuck in the mode described in the previous step, 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. Go to next step.
  7. Note similarity to LDP Monitor screen found under DRBIII® Monitors. Failure modes are fewer in the System Test than DRBIII® LDP Monitor. System Test only stores Small Leak DTC to indicate problem with system. No other type of failure mode indication given. Go to next step.
  8. 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. Connect the DRBIII® to the data link connector. Start engine and turn all accessories off. Go to next step.
  9. 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? If no, test is complete. If yes, check for any related technical service bulletins that apply to symptom. If repaired DTC has reset, proceed to appropriate DTC test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . If necessary, go to TROUBLE SHOOTING - NO CODES - CARS - EXCEPT SEBRING COUPE & STRATUS COUPE article for diagnosis by symptom.
