DTC P0970: Problem in A/T Clutch Pressure Control Solenoid Valve C CircuitNOTE:
^ Before you troubleshoot, record all freeze data and any on-board snapshot, 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.
1. Clear the DTC with the HDS.
2. Test-drive the vehicle for several minutes in the D position through all five gears.
3. Check that DTC P0970 recurs.
Is DTC P0970 indicated?
YES - Go to step 7.
NO - Go to step 4.
4. Choose Clutch Pressure Control Solenoid C in Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve C with the HDS.
Is the result NORMAL?
YES - Go to step 5.
NO - Go to step 7.
5. Command A/T clutch pressure control solenoid valve C at 1.0 A in Clutch Pressure Control Solenoid Control menu.
6. Monitor the OBD status for P0970 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
YES - Go to step 7.
NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at A/T clutch pressure control solenoid valve C and the PCM. If the HDS indicates NOT COMPLETED, return to step 4 and recheck.
7. Turn the ignition switch OFF.
8. Disconnect the A/T clutch pressure control solenoid valve C connector.
9. Measure the resistance between A/T clutch pressure control solenoid valve C connector terminals No. 1 and No. 2.
Is there 3 - 10 Ohms?
YES - Go to step 10.
NO - Replace A/T clutch pressure control solenoid valve C, then go to step 13.
10. Check for continuity between A/T clutch pressure control solenoid valve C connector terminal No. 2 and body ground.
Is there continuity?
YES - Go to step 11.
NO - Repair open in the wire between A/T clutch pressure control solenoid valve C and ground (G101), or repair poor ground (G101), then go to step 13.
11. Turn the ignition switch ON (II).
12. Measure the voltage between A/T clutch pressure control solenoid valve C connector terminals No. 1 and No. 2.
Is there voltage?
YES - Go to step 16.
NO - Repair open or short in the wire between PCM connector terminal C7 and A/T clutch pressure control solenoid valve C, then go to step 13.
13. Clear the DTC with the HDS.
14. Test-drive the vehicle for several minutes in the D position through all five gears.
15. Monitor the OBD status for P0970 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate PASSED?
YES - Troubleshooting is complete.
NO - Check for poor connections or loose terminals at A/T clutch pressure control solenoid valve C and the PCM, then go to step 1.
16. Update the PCM if it does not have latest software, or substitute a known-good PCM.
17. Test-drive the vehicle for several minutes in the D position through all five gears.
18. Monitor the OBD status for P0970 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate PASSED?
YES - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM.
NO - If the PCM was updated and screen indicates FAILED, substitute a known-good PCM, then go to step 17. If the PCM was substituted, check for poor connections or loose terminals at A/T clutch pressure control solenoid valve C and the PCM, then go to step 1 and recheck. If the screen indicates NOT COMPLETED, go to step 17.
