REAR DIFF SOLENOID (INT’L)
Differential Solenoid Overview
The differential solenoid is located on the rear gear case. The
solenoid actuates an engagement dog, which locks and unlocks
the rear differential. Refer to Chapter 7 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 seat.
When the switch is pushed to activate “TURF”, a ground signal
is provided to the ECU from the AWD / 2WD / TURF Switch.
Depending on engine speed and gear position criteria, the ECU
energizes the Rear Diff Solenoid Relay allowing it to enable the
differential solenoid.
If the rear differential fails to switch from operational modes:
• Check the solenoid and relay connectors. Look for
loose wires or bad connections.
• Check for power from the relay connector, to ensure the
solenoid has power to be activated.
• Check the AWD / 2WD / TURF Switch wires for loose
connections.
• Remove solenoid from rear differential and ensure the
solenoid plunger is actuating.
CAUTION
Do not power the solenoid with 12 Volts for more
than 1 second, or damage may occur to solenoid.
