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. 11
• 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.
