ELECTRICAL Differential Solenoid (INT'L Models)
The differential solenoid is located on the rear gear caseThe solenoid actuates an engagement dog, which locks and unlocks the rear differentialRefer to Chapter for more information on the rear differential mechanical operation
Differential Solenoid Circuit Operation The Rear Diff Solenoid Relay is attached to the rear plastic LH panel divider behind the driver's seatWhen the switch is pushed to activate "TURF" mode, ground signal is provided to the ECU from the AWD2WDTURF SwitchDepending on engine speed and gear position criteria, the ECU energizes the Rear Diff Solenoid Relay allowing it to enable the differential solenoidIf the rear differential fails to switch from operational modes: Check the solenoid and relay connectorsLook for loose wires or bad connections Check for power from the relay connector, to ensure the solenoid has power to be activated Check the AWD2WDTURF Switch wires for loose connections Remove solenoid from rear differential and ensure the solenoid plunger is actuating
