P0980

DTC P0980: Open in Shift Solenoid Valve Circuit

NOTE:
^ Record all freeze data and review General Troubleshooting Information 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 D5 position.
3. Check that DTC P0980 recurs.
Is DTC P0980 indicated?
YES - Go to step 7.
NO - Go to step 4.
4. Select SHIFT SOL TEST in MISC. TEST MENU, then carry out A/T SHIFT SOL C test in SHIFT SOL TEST MENU with the HDS.
5. Start the engine, and shift to the P position.
6. Check the OBD STATUS in DTCs MENU for a pass/fail test for code P0980.
Did the result indicate a fail?
YES - Go to step 7.
NO - Intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETE, return to step 4 and recheck.
7. Turn the ignition switch OFF.
8. Jump the SCS line with the HDS.
9. Disconnect PCM connector A (73P).





10. Measure the resistance between PCM connector terminals A13 and A39 or A40.
Is there 12 - 25 ohms ?
YES - Check for loose or poor connections at PCM connector terminal A13. If the connections are OK, update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
NO - Go to step 11.
11. Inspect shift solenoid valve C.
Is shift solenoid valve C OK?
YES - Go to step 12.
NO - Replace shift solenoid valve C, then go to step 14.
12. Remove the solenoid harness.





13. Check for continuity between solenoid harness connector terminal No. 2 and shift solenoid valve C connector.
Is there continuity ?
YES - Repair open in the wire between PCM connector terminal A13 and shift solenoid valve C, then go to step 14.
NO - Replace solenoid harness, then go to step 14.
14. Clear the DTC with the HDS.
15. Start the engine in the P position.
16. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0980.
Did the result indicate a pass?
YES - The problem has been corrected.
NO - Return to step 1 and recheck.
