F1: CHECK THE CONTINUITY OF THE TCC SOLENOID CIRCUIT
1. Raise and support the vehicle.
2. Disconnect the transmission vehicle harness connector, GB5.
3. Disconnect the PCM electrical connector GB1.
4. Measure the resistance of the TCC solenoid circuit between the transmission vehicle harness connector GB5 pin 14, (NW) and the PCM electrical connector GB1 pin 5, (NW).
^ Is the resistance less than 0.5 Ohms?
-> Yes
INSTALL a new PCM. CLEAR DTC. TEST the system for normal operation.
-> No
REPAIR the circuit between the transmission vehicle harness connector GB5 pin 14, (NW) and the PCM electrical connector GB1 pin 5, (NW). CLEAR DTC. TEST the system for normal operation.
