NOTE:

• Before you troubleshoot, record all freeze data and

any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-3).

• 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. Clear the DTC with the HDS.

3. Start the engine with the shift lever in P, and wait

for at least 1 second.

4. Check for Temporary DTCs or DTCs with the HDS.

Go to step 8.

Intermittent failure, the system is OK at this

time. Check for intermittent short to body ground in
the wire between shift solenoid valve E and the
PCM.

5. Turn the ignition switch to LOCK (0).

6. Jump the SCS line with the HDS.

7. Disconnect PCM connectors B (44P) and C (44P).

8. Measure the resistance between PCM connector

terminals B24 and C40.

Go to step 9.

Go to step 18.

9. Disconnect the shift solenoid wire harness

connector.

10. Check for continuity between PCM connector

terminals B24 and C40.

Repair short to body ground in the wire

between PCM connector terminal B24 and the shift
solenoid wire harness connector, then go to step
13.

Go to step 11.

11. Inspect shift solenoid valve E and the shift solenoid

harness (see page 14-215).

12. Replace either shift solenoid valve E or the shift

solenoid wire harness (see page 14-217),
whichever failed the test, then go to step 13.

13. Reconnect all connectors.

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

15. Clear the DTC with the HDS.

16. Start the engine with the shift lever in P, and wait

for at least 1 second. Then shift to N, and wait for at
least 1 second.

17. Check for Temporary DTCs or DTCs with the HDS.

Check for intermittent short to body ground

in the wire between shift solenoid valve E and the
PCM, then go to step 1.

Troubleshooting is complete. If any other

Temporary DTCs or DTCs were indicated, go to the
indicated DTC’s troubleshooting.

18. Reconnect all connectors.

19. Update the PCM if it does not have the latest

software (see page 11-227), or substitute a known-
good PCM (see page 11-7).

20. Start the engine with the shift lever in P, and wait

for at least 1 second. Then shift to N, and wait for at
least 1 second.

21. Check for Temporary DTCs or DTCs with the HDS.

Check for intermittent short to body ground

in the wire between shift solenoid valve E and the
PCM. If the PCM was updated, substitute a known-
good PCM (see page 11-7), then go to step 20. If the
PCM was substituted, go to step 1.

If the PCM was updated, troubleshooting is

complete. If the PCM was substituted, replace the
original PCM (see page 11-228). If any other
Temporary DTCs or DTCs were indicated, go to the
indicated DTC’s troubleshooting.

for at least 1 second.

4. Check for Temporary DTCs or DTCs with the HDS.

Go to step 8.

Go to step 5.

5. Select Shift Solenoid Valve E in the Miscellaneous

Test Menu, and test shift solenoid valve E with the
HDS.

Go to step 6.

Go to step 8.

6. Start the engine with the shift lever in P, and wait

for at least 1 second.

7. Monitor the OBD STATUS for P0985 in the DTCs

MENU with the HDS.

Go to step 8.

If the HDS indicates PASSED, intermittent

failure, the system is OK at this time. Check for
intermittent short to body ground in the wire
between shift solenoid valve E and the PCM. If the
HDS indicates NOT COMPLETED, go to step 5.

8. Turn the ignition switch to LOCK (0).

9. Jump the SCS line with the HDS.

10. Disconnect PCM connectors B (44P) and C (44P).
