16. Reconnect all connectors.
17. Turn the ignition switch to ON (II).
18. Clear the DTC with the HDS.
19. Start the engine with the shift lever in P, and wait
for at least 1 second. Test-drive the vehicle in D,
and let the transmission shift through 1st to 3rd
gears, then drive the vehicle in 3rd gear for at least
1 second.
20. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals between shift solenoid valve B and the
PCM, then go to step 1.
Go to step 21.
21. Monitor the OBD STATUS for P0977 in the DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 20,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor
connections or loose terminals between shift
solenoidvalveBandthePCM,thengotostep1.If
the HDS indicates NOT COMPLETED, go to step 19. 22. Reconnect all connectors.
23. 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).
24. Start the engine with the shift lever in P, and wait for at least 1 second. Test-drive the vehicle in D,
and let the transmission shift through 1st to 3rd
gears, then drive the vehicle in 3rd gear for at least
1 second.
25. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals between shift solenoid valve B and the
PCM. If the PCM was updated, substitute a known-
good PCM (see page 11-7), then go to step 24. If the
PCM was substituted, go to step 1.
Go to step 26.
26. Monitor the OBD STATUS for P0977 in the DTCs MENU with the HDS.
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 in step 25,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor
connections or loose terminals between shift
solenoid valve B and the PCM. If the PCM was
updated, substitute a known-good PCM (see page

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. Test-drive the vehicle in 1st gear with the shift lever in D 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 C in the Miscellaneous Test Menu, and test shift solenoid valve C with the
HDS.
Go to step 6.
Go to step 8.
6. Test-drive the vehicle in 1st gear with the shift lever in D for at least 1 second.
7. Monitor the OBD STATUS for P0979 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 C 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).
