REAR DIFF SOLENOID SERVICE
DIFFERENTIAL SOLENOID OVERVIEW
The differential solenoid
q
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.
DIFFERENTIAL SOLENOID CIRCUIT
OPERATION
The Rear Diff Solenoid Relay is attached to the rear
portion of the main frame and can be accessed by tilting
the rear cargo box.
When the switch is pushed to activate “TURF”, a ground
signal is provided to the ECU from the AWD 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 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.
