^ 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. Turn the ignition switch OFF.
2. Disconnect PCM connector A (31P).
3. Check for continuity between PCM connector terminal A23 and body ground, and between terminal A24 and body ground.
Is there continuity?
YES - Go to step 4.
NO - Repair open in the wire between PCM connector terminals A23, A24, and ground (G101), or repair poor ground (G101).
4. Disconnect PCM connector C (22P).
5. Measure the resistance between PCM connector terminals C4 and A23 or A24.
Is there less than 12 Ohms?
YES - Go to step 6.
NO - 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.
6. Disconnect shift solenoid valve B connector.
7. Check for continuity between PCM connector terminals C4 and A23 or A24.
Is there continuity?
YES - Repair short to ground in the wire between PCM connector terminal C4 and shift solenoid valve B.
NO - Replace shift solenoid valve B.
