WARNING: This page is about a different variant/trim than selected.
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review GENERAL TROUBLESHOOTING INFORMATION .
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
- If DTC P0963 is stored in the PCM, the transmission does not shift to 2nd or 5th gear because of the fail-safe function.

Is there continuity?
YES -Replace the PCM (see PCM REPLACEMENT ).
NO -Repair an open in the wires between:
- PCM connector terminal B1 and body ground (G101) (see ENGINE WIRE HARNESS (ENGINE SECTION) (D) ), or repair poor body ground (G101).
- PCM connector terminal B40 and body ground (G101) (see ENGINE WIRE HARNESS (ENGINE SECTION) (D) ), or repair poor body ground (G101).
