VEHICLE SPEED SENSOR
Speed Sensor Location
The speed sensor is located in the transmission transfer
case cover, accessed through the rear LH wheel well area.
Speed Sensor Testing
Special Tools Required:
Static Timing Light Harness (PN 2871745)
Hall Sensor Probe Harness (PN 2460761)
1. Disconnect the 3 wire harness from the speed sensor
and remove the sensor from the transmission.
2. Connect the wires from the Static Timing Light
Harness to the sensor 3 pin connector using the Hall
Sensor Probe Harness (PN 2460761).
3. Pass a screwdriver back and forth in front of the
sensor tip.
4. Be sure connections are good and 9V battery is in
good condition. If the light flashes, the sensor is good.
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 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 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.
Do not power the solenoid with 12 Volts for more
than 1 second, or damage may occur to solenoid.
