BRAKE PEDAL SWITCH INSPECTION

The Brake Pedal Switch is mounted near the Brake
Pedal Assembly. When the brake pedal is depressed this
switch will turn from active to inactive. This can be
monitored using Digital Wrench ®. If the status does not
switch when depressed, proceed with further testing.
1. Disconnect electrical connector from sensor.
2. Inspect sensor and connector for moisture or
corrosion. If moisture or corrosion is found, clean first
and re check.
3. With connector disconnected, check resistance
across pins on the sensor. When switch is closed
(brake pedal not depressed) resistance should be
less than 0.5 ohms. With switch open (brake pedal
depressed) resistance should show an open (OL).
4. If the sensor test fails, resistance is not within
specification; the sensor should be replaced.
5. If the sensor test passes, resistance is within
specification, inspect the circuit for correct operation.
If there is a concern found with the circuit repair and
recheck operation.
6. If the concern is still present, it is possible that there
may be a concern with the ECU.

AWD / 2WD / TURF SWITCH

1. Disconnect the AWD / 2WD / TURF switch harness
by depressing the connector locks and pulling on the
connector. Do not pull on the wiring.
2. Test between the 3 sets of outputs (AWD / 2WD /
TURF). If any of the tests fail, replace the switch
assembly.
• Move the switch to AWD. There should be continuity
between switch pins 2 and 4; 6 and 8.
• Move the switch to 2WD. There should be no
continuity between any pins.
• Move the switch to TURF. There should be continuity
between switch pins 1 and 2; 5 and 6.

NOTICE
Pins 2 and 9 provide power and ground to light the
switch lamp.

OPERATION OVERVIEW

• With the key on and the AWD switch "ON", 12 VDC
power is present at the hub coil.
• When the AWD switch is "ON", and if the criteria is
met, the Engine Controller provides a ground path
(brown/white wire). When this occurs the AWD icon
should display in the instrument cluster.
• The AWD system must be grounded to operate.

DIAGNOSING SYSTEM FAILURES

1. Verify AWD switch is functional and that a minimum
of 11 volts is present at the hub coil.
