AWD / Turf Switch Test
Differential Solenoid Test
Test Procedure
Using a known good 12V power source, connect directly to the Differential Solenoid at the harness
connection located near the left hand frame rail. Connect battery positive to the solenoid side of the
harness on the Orange/Red and Battery negative on the Blue wire. Audible operation of the solenoid
should be noted. Caution: DO NOT POWER THE SOLENOID WITH 12V FOR MORE THAN 1
SECOND OR DAMAGE TO THE SOLENOID MAY OCCUR.
What does passing
this test indicate?
Passing this test indicates the solenoid is operating correctly.
What does failing
this test indicate?
If there is no audible operation coming from the differential solenoid inspect wire harness leading up to
solenoid. If all connections are good, replace the solenoid.
AWD OUT Test
Test Procedure
With the ignition and AWD switches in the "on" position. Disconnect the connector going to the AWD
hub coil. Use a Digital Multimeter to check for power on the harness side of the connector on the Gray
wire. Your reading should be at or near battery voltage.
What does passing
this test indicate?
Passing this test indicates the PDM and AWD switch are operating correctly.
What does failing
this test indicate?
Failing this test indicates there may be a problem with the AWD switch, wire harness or PDM.
AWD / Turf Switch Test
Test Procedure
The following tests must be performed with the Ignition switch in the ON position.
1. Verify switch is properly lighting. There will be one small light at the bottom of the switch illuminated
at all times. A larger light will illuminate when the switch is placed in AWD.
2. Place the switch is in the lowest or "Turf" mode position. Using a Digital Multimeter, verify the white/
green wire leaving the switch is at or near battery voltage. With the switch in the top or AWD position,
verify the gray wire leaving the switch is at or near battery voltage.
What does passing
this test indicate?
1. Passing this test indicates there is a power source to the AWD/Turf Switch.
2. Passing both of these tests indicates the switch is functioning normally.
What does failing
this test indicate?
1. Failing this test indicates they may be a problem with the power source to the switch; verify the wire
harness. If there is power at the switch and no illumination replace the switch.
2. Failing either of these tests indicates the switch is not operating normally. If test 1 has been completed
and passed, replace the switch.
