- Open circuit between TCC control solenoid terminal B and TCM terminal B9
- Open circuit between TCC control solenoid terminal A and TCM terminal B4
- Short to ground in wiring harness between TCC control solenoid terminal B and TCM terminal B9
- Short to ground in wiring harness between TCC control solenoid terminal A and TCM terminal B4
