Transmission Range Switch ATP RVS Switch (Open or Short)
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information How to Troubleshoot the A/T System.
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
1. Turn the ignition switch to ON (II).
2. Shift to R, and check the A/T R Switch signal with the HDS in the A/T Data List.
Is the A/T R Switch ON?
YES -
Go to step 3.
NO -
Check for proper transmission range switch installation Testing and Inspection, adjust the shift cable Adjustments, then recheck.
3. Check the Reverse Switch (ATPRVS) signal with the HDS in the A/T Data List.
Is the Reverse Switch (ATPRVS) ON?
YES -
Intermittent failure, the system is OK at this time.
NO -
Go to step 4.
4. Turn the ignition switch to LOCK (0).
5. Disconnect the transmission range switch connector.
6. Using a jumper wire, jump the transmission range switch connector terminal No. 2 and body ground.
7. Turn the ignition switch to ON (II).
8. Check the Reverse Switch (ATPRVS) signal with the HDS in the A/T Data List.
Is the Reverse Switch (ATPRVS) ON?
YES -
Replace the transmission range switch Service and Repair, then go to step 14.
NO -
Repair an open in the wire between PCM connector terminal B22 and the transmission range switch, then go to step 14. If the circuit is OK, go to step 9.
9. Connect the transmission range switch connector.
10. Update the A/T software in the PCM if it does not have the latest software PCM Update, or substitute a known-good PCM.
11. Start the engine in P. With the brake pedal pressed, shift to R, and wait for at least 2 seconds in R, then shift to N.
12. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P1717 indicated?
YES -
If the PCM was updated, substitute a known-good PCM, then go to step 11. If the PCM was substituted, go to step 1.
NO -
Go to step 13.
13. Monitor the OBD STATUS for P1717 in the DTCs MENU with the HDS.
Does the HDS indicate PASSED?
YES -
If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM Service and Repair. If any other Pending or Confirmed DTCs were indicated in step 12, go to the indicated DTC's troubleshooting.
NO -
If the HDS indicates FAILED, check for poor connections or loose terminals between the transmission range switch and the PCM. If the PCM was updated, substitute a known-good PCM, then go to step 11. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 11.
14. Connect the transmission range switch connector.
15. Clear the DTC with the HDS.
16. Start the engine in P. With the brake pedal pressed, shift to R, and wait for at least 2 seconds in the R, then shift to N.
17. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P1717 indicated?
YES -
Check for poor connections or loose terminals between the transmission range switch and the PCM, then go to step 1.
NO -
Go to step 18.
18. Monitor the OBD STATUS for P1717 in the DTCs MENU with the HDS.
Does the HDS indicate PASSED?
YES -
Troubleshooting is complete. If any other Pending or Confirmed DTCs were indicated in step 17, go to the indicated DTC's troubleshooting.
NO -
If the HDS indicates FAILED, check for poor connections or loose terminals between the transmission range switch and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 16.
