L1: CHECK THE SSD SOLENOID CIRCUIT VOLTAGE SUPPLY
1. Raise and support the vehicle.
2. Disconnect the transmission vehicle harness connector.
3. Switch the ignition to the RUN position.
4. Measure the voltage between the transmission vehicle harness connector GB5 pin 3, (GB) and GROUND.
^ Is the voltage less than 12 Volts?
-> Yes
Goto [L2]
-> No
Goto [L4]

L2: CHECK THE SSD SOLENOID CIRCUIT VOLTAGE SUPPLY
1. Switch the ignition to the OFF position.
2. Disconnect the shift solenoid power supply electrical connector GB2.
3. Switch the ignition to the RUN position.
4. Measure the voltage between GB2 pin 4, (GB) and GROUND.
^ Is the voltage less than 12 Volts?
-> Yes
Goto [L3]
-> No
REPAIR the circuit between GB2 pin 4, (GB) and the transmission vehicle harness connector GB5 pin 3, (GB). CLEAR DTC. TEST the system for normal operation.

L3: CHECK THE VOLTAGE SUPPLY FROM THE FRONT POWER DISTRIBUTION BOX
1. Measure the voltage supply from fuse 6 at the front distribution box.
^ Is the voltage less than 12 Volts?
-> Yes
INSTALL a new fuse. CLEAR DTC. TEST the system for normal operation. If the fuse fails CHECK the front distribution box.
-> No
REPAIR the circuit between GB2 pin 4, (GB) and the output side of fuse 6 at the front distribution box. CLEAR DTC. TEST the system for normal operation.

L4: CHECK THE CONTINUITY OF THE SSD SOLENOID SIGNAL CIRCUIT
1. Switch the ignition to the OFF position.
2. Disconnect the PCM electrical connector GB1.
3. Measure the resistance between the transmission SSD solenoid GB5 pin 3, (GB) and the PCM electrical connector GB1 pin 04, (BR).
^ Is the resistance 24 Ohms?
-> Yes
INSTALL a new PCM. CLEAR DTC. TEST the system for normal operation.
-> No
Goto [L5]

L5: CHECK THE CONTINUITY OF THE SSD SOLENOID SIGNAL CIRCUIT
1. Measure the resistance between the transmission SSD solenoid GB5 pin 5, (BR) and the PCM electrical connector GB1 pin 04, (BR).
^ Is the resistance less than 0.5 Ohms?
-> Yes
INSTALL a new transmission SSD solenoid. CLEAR DTC. TEST the system for normal operation.
-> No
REPAIR the circuit between the transmission SSD solenoid GB5 pin 5, (BR) and the PCM electrical connector GB1 pin 04, (BR). CLEAR DTC. TEST the system for normal operation.
