REAR DIFF SOLENOID (INT’L)
Differential Solenoid Overview
The differential solenoid is located on the rear portion of
the transmission case. The solenoid actuates a shift fork
with an engagement dog, which locks and unlocks the rear
differential. Refer to Chapter 8 for more information.
Differential Solenoid Circuit Operation
The Rear Diff Solenoid Relay is attached to the lower
airbox bracket and can be accessed through the right rear
wheel well.
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 diff 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.
Do not power the solenoid with 12 Volts for more
than 1 second, or damage may occur to solenoid.
