Check the cause
Inspect the transmission wiring harness leading to the Clutch ODD solenoid for rubbed wires, corrosion, or damaged pins that could cause a short.
Repair steps
Circuit Inspection
Inspect the transmission wiring harness leading to the Clutch ODD solenoid for rubbed wires, corrosion, or damaged pins that could cause a short.
Controller Replacement Note
