1. Check if any of the following conditions exist.

2. The ECM has been disconnected or replaced.

3. The Battery power has been disconnected.

4. The APPS has been disconnected or replaced.

5. If any of the conditions exist, perform the following steps, otherwise, go to step 8.

6. APPS Programming Procedure: Reassemble all components. Turn the ignition key to the ON or RUN position. Without starting the engine, slowly press the throttle pedal to the floor and then slowly release.

7. This step must be done (only once) to ensure the accelerator pedal position sensor calibration has been programmed in the ECM.

8. Caution: Do not attempt to adjust screws or disassemble the APPS sensor. These settings are set at the factory and are not intended to be changed.

9. If the PCM has been replaced, do the following: (Otherwise go to step 12).

10. Note: If the Powertrain Control Module has been changed and the correct VIN and mileage have not been programmed, a DTC will be set in the ABS and Airbag modules.

11. For ABS and Airbag Systems: Action: Enter correct VIN and Mileage in PCM. Erase ABS and Airbag module codes.

12. If the PCM has not been replaced, do the following:

13. All Trouble Codes should be repaired before continuing, if not, return to Symptom list and follow suggested test. After all DTC's are repaired, return to this test and continue.

14. Connect the DRB III to the Data Link Connector. Ensure the fuel tank is at least 1/4 full. Turn off all accessories.

15. Note: The best way to verify an OBD II DTC repair is to allow the PCM to run the appropriate "Trip" and increment a Good Trip which verifies that the repair was successful.

6. Note: A component DTC will require 2 minutes of engine run time without any DTC's to increment Good Trip.

17. Note: A monitor DTC, other than a misfire DTC, will require using the DRB pre-test screens to allow the technician to meet the requirements to run that monitor.

18. Note: A misfire DTC will require using Similar Conditions window to attempt to duplicate the operating conditions when the DTC was set to verify the repair.

19. If this verification procedure is being performed after a Component CODE repair, do the following:

20. After the ignition has been off for at least 10 seconds, restart the vehicle and run 2 minutes.

21. Did Starts Since Set and Good Trip change to one or more? If yes, repair is complete, go to step 23, otherwise continue with step 22.

22. Look for any new DTC's set during the test. If there are any new DTC's, return to Symptom list and follow suggested path.

23. If the Good Trip counter changed to one or more, the repair was successful.

24. Erase Trouble Codes.

25. Disconnect the DRB.

26. If this verification procedure is being performed after a MONITOR TROUBLE CODE repair, do the following:

27. With the DRB III, monitor the pre-test enabling conditions until all conditions have been met to run the appropriate monitor. Run the appropriate monitor for the repaired DTC.

28. If the repaired OBD II trouble code has reset, or the OBD II monitor failed after running, the repair is not complete. Check for any Technical Service Bulletins or flash updates and return to Symptom list.

29. If a new DTC has set, return to Symptom list and follow the path specified for that code.

30. If the monitor ran, and the Good Trip counter changed to one or more, the repair was successful.

31. Erase Trouble Codes.

32. Disconnect the DRB.

33. If this verification procedure is being performed after a MISFIRE TROUBLE CODE repair, do the following:

34. With DRB III, monitor Similar Conditions to attempt to duplicate the conditions that the vehicle was operating at when the code was set. If conditions can be duplicated, Misfire Good Trip counter will change to one or more. If not Continue with step 37.

35. If the repaired OBD II trouble code has reset, or the OBD II monitor failed after running, the repair is not complete. Check for any technical service bulletins or flash updates and return to Symptom list.

36. If a new DTC has set, return to Symptom list and follow the path specified for that code.

37. If the monitor ran, and the Good Trip counter changed to one or more, the repair was successful.

38. Erase Trouble Codes.

39. Disconnect the DRB.
