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.
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.
CAUTION
Do not power the solenoid with 12 Volts for more than 1
second, or damage may occur to solenoid.
