Switches
Each time the vehicle is used, switches should be
checked for proper operation. Use the following list
for reference.
A. Ignition/start switch — engine will run; starter
will engage.
B. 2WD/4WD selector switch — differential will
engage (4WD)/disengage (2WD).
C. Reverse/neutral/high/low switch — R/N/H/L
will be indicated on the LCD.
D. Headlight switch — high beam, low beam, and
lights off can be selected.
E. Brake switch — brakelight illuminates and
starter can be engaged with vehicle in gear.
Electrical Connections
The electrical connections should be checked periodi-
cally for proper function. In case of an electrical fail-
ure, check fuses, connections (for tightness, corrosion,
damage), and/or bulbs.
Accessory
Receptacle/Connector
NOTE: This test procedure is for either the recep-
tacles or the connectors.
VOLTAGE
1. Turn the ignition switch to the ON position; then
set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the red/white wire or
the positive connector; then connect the black
tester lead to ground.
3. The meter must show battery voltage.
NOTE: If the meter shows no battery voltage,
troubleshoot the battery, fuse, receptacle, connec-
tor, or the main wiring harness.
Brakelight Switch
The switch connector is the two-prong black connector
below the master cylinder.
NOTE: The ignition switch must be in the ON
position.
VOLTAGE
(Wiring Harness Connector)
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the orange wire; then
connect the black tester lead to ground.
PR276A
3. The meter must show battery voltage.
NOTE: If the meter shows no battery voltage,
troubleshoot the battery, fuse, switch, or the main
wiring harness.
NOTE: If the meter shows battery voltage, the
main wiring harness is good; proceed to test the
switch/component, the connector, and the switch
wiring harness for resistance.
RESISTANCE (Switch Connector)
NOTE: The brake pedal must be depressed for
this test.
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to one black wire; then
connect the black tester lead to the other black
wire.
! CAUTION
Always disconnect the battery when performing
resistance tests to avoid damaging the multimeter.
