NOTE:

• Record all freeze data and review General

Troubleshooting Information (see page 14-8) before
you troubleshoot.

• 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, and shift to the D position.

3. Check that DTC P0979 recurs.

Go to step 7.

Go to step 4.

4. Choose Shift Solenoid C in Miscellaneous Test

Menu, and test the shift solenoid valve C with the
HDS.

5. Start the engine, and shift to the D position.

6. Monitor the OBD status for P0979 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 the GRN wire for an intermittent short
to ground between shift solenoid valve C and PCM.
If the tester 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 A (31P) and C (22P).

10. Measure the resistance between PCM connector

terminals C2 and A9.

Go to step 11.

Update the PCM if it does not have the latest

software, or substitute a known-good PCM
(see page 14-11), then recheck. If the symptom/
indication goes away with a known-good PCM,
replace the original PCM.

11. Disconnect the shift solenoid harness connector at

the transmission housing.

12. Check for continuity between PCM connector

terminals C2 and A9.

Repair short to ground in the wire between

PCM connector terminal C2 and the shift solenoid
harness connector, then go to step 13.

Check shift solenoid valve C, and check for a

short in the shift solenoid harness in the
transmission (see page 14-258). Replace shift
solenoid valve C and/or shift solenoid harness,
then go to step 13.

13. Clear the DTC with the HDS.

14. Start the engine, and shift to the D position.

15. Monitor the OBD status for P0979 in the DTCs/

Freeze Data in A/T Mode Menu for a pass/fail.

Troubleshooting is completed.

Return to step 7 and recheck.

Wire side of female terminals

Is ther e continuity?

Does the r esult indicate a passed?

NOTE:

• Record all freeze data and review General

Troubleshooting Information (see page 14-8) before
you troubleshoot.

• 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 P0980 recurs.

Go to step 7.

Go to step 4.

4. Choose Shift Solenoid C in Miscellaneous Test

Menu, and test the shift solenoid valve C with the
HDS.

5. Start the engine in the P position.

6. Monitor the OBD status for P0980 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 C and PCM. If the tester
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 A (31P) and C (22P).

10. Measure the resistance between PCM connector

terminals C2 and A9.

Check for loose or poor connections at PCM

connector terminal C2. If the connection is OK,
update the PCM if it does not have the latest
software, or substitute a known-good PCM
(see page 14-11), then recheck. If the symptom/
indication goes away with a known-good PCM,
replace the original PCM.

11. Disconnect the shift solenoid harness connector at

the transmission housing.

12. Measure the resistance between shift solenoid

harness connector terminal No. 1 and body ground.

Repair open in the wire between PCM

connector terminal C2 and the shift solenoid
harness connector, then go to step 13.

Check shift solenoid valve C, and check for an

open in the shift solenoid harness in the
transmission (see page 14-258). Replace shift
solenoid valve C and/or shift solenoid harness,
then go to step 13.

13. Clear the DTC with the HDS.

14. Start the engine in the P position.

15. Monitor the OBD status for P0980 in the DTCs/
