  1. Perform On-Board Diagnostic II (OBD-II) System Check. See SELF-DIAGNOSTICS - INTRODUCTION article. Retrieve and record FREEZE FRAME and/or FAIL RECORDS data for each DTC set. Go to next step.
  2. Using Tech 2 scan tool, clear DTCs. Using Connector Test Adapter Kit (J35616-A) and DVOM, backprobe across VSS harness connector signal circuit (Purple/White wire) and sensor ground circuit (Black wire). Raise and support vehicle. Start engine and place transmission in gear. If voltage is constant, go to step  5. If voltage is not constant, go to next step.
  3. If voltage varies, see DIAGNOSTIC AIDS . If voltage does not vary, go to next step.
  4. If scan tool displays NO VOLTAGE, go to step  11. If scan tool does not display NO VOLTAGE, go to step  12.
  5. With vehicle still raised, disconnect VSS connector. With engine running, place transmission in gear. Using a DVOM, check voltage across signal circuit (Purple/White wire) and sensor ground circuit (Black wire) at VSS. If voltage varies with RPM, go to step  7. If voltage does not vary, go to next step.
  6. Replace VSS. After replacing sensor, go to step  12.
  7. Check for faulty connection at VCM and VSS. If faulty connection is found, go to step  9. If connections are okay, go to next step.
  8. Check for open or short in sensor ground circuit (Black wire) and signal circuit (Purple/White wire) between VCM and VSS. If problem is found, go to step  10. If no problem is found, go to step  12.
  9. Repair connection(s) as necessary. After repair, go to step  12.
  10. Repair open or short as necessary. After repair, go to step  12.
  11. Replace VCM. Program replacement VCM. See PROGRAMMING . After replacing VCM, go to next step.
  12. Using scan tool, select DTC, CLEAR INFO function. Start engine and allow it to reach operating temperature. Using scan tool, select DTC, SPECIFIC function and enter DTC P0500. Operate vehicle within conditions required to set DTC. If scan tool displays RAN AND PASSED, go to next step. If scan tool does not display RAN AND PASSED, return to step  2.
  13. Using scan tool, select Read and Record INFO, REVIEW INFO function. If any undiagnosed DTCs are displayed, diagnose affected DTCs. If no DTCs are displayed, system is okay.
