- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information How To Troubleshoot The CVT System.
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1. Make sure the shift cable adjustment Adjustments.

2. Turn the ignition switch to ON (II).

3. Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPL, and ATPFWD input with the HDS to the following table, in each shift lever position.










Are the transmission range switch signals OK?

YES -

Intermittent failure, the system is OK at this time.�

NO -

Go to step 4.

4. Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPL, and ATPFWD inputs with the HDS to the table in step 3.

Go to step 14.

NO -

Record any input that incorrectly indicated ON, then go to step 5.

16. Check for continuity between transmission range switch connector terminal No. 2 and body ground.





Is there continuity?

YES -

Replace the transmission range switch Service and Repair.�

NO -

Repair an open in the wire between the transmission range switch and body ground (G102), or repair poor body ground (G102).�
