NOTE:
• Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information (see page 14-5).
• This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
1. Clear the DTC with the HDS.
2. Start the engine in the P position.
3. Check that DTC P0983 recurs.
Go to step 7.
Go to step 4.
4. Choose Shift Solenoid D in the Miscellaneous Test Menu, and test shift solenoid valve D with the HDS.
Go to step 5.
Go to step 7.
5. Start the engine in the P position.
6. Monitor the OBD STATUS for P0983 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.
Go to step 7.
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at shift solenoid valve D and the PCM. If the HDS indicates NOT COMPLETED, return to step 4 and recheck.
7. Turn the ignition switch OFF.
8. Jump the SCS line with the HDS.
9. Disconnect PCM connectors B (44P) and C (44P).
10. Measure resistance between PCM connector terminals B26 and C40 or C44.
Go to step 15.
Go to step 11.

software (see page 14-9), or substitute a known-good PCM (see page 14-10).
16. Start the engine in the P position.
17. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.
If the PCM was updated, substitute a known-good PCM (see page 14-10), then recheck. If the PCM was substituted, go to step 1.
If DTC P0983 is not indicated, or if any other DTCs are indicated, go to step 18.
18. Monitor the OBD STATUS for P0983 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.
If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM; R20A1 and R20A2 engine models (see page 11-226), K24Z1 engine model (see page 11-613). If any other DTCs were indicated on step 17, go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor connections and loose terminals at shift solenoid valve D and the PCM. If the PCM was updated, substitute a known-good PCM (see page 14-10), then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, keep idling until a result comes on.
19. Clear the DTC with the HDS.
20. Start the engine in the P position.
21. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.
Check for poor connections and loose terminals at shift solenoid valve D and the PCM, then go to step 1.
If DTC P0983 is not indicated, or if any other DTCs are indicated, go to step 22.
22. Monitor the OBD STATUS for P0983 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.
Troubleshooting is complete. If any other DTCs were indicated on step 21, go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor connections and loose terminals at shift solenoid valve D and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, return to step 20 and recheck.

1. Clear the DTC with the HDS.
2. Start the engine in the P position.
3. Check that DTC P0985 recurs.
Go to step 7.
Go to step 4.
4. Choose Shift Solenoid E in the Miscellaneous Test Menu, and test shift solenoid valve E with the HDS.
Go to step 5.
Go to step 7.
5. Start the engine in the P position.
