2WD/4HI Switch INSPECTION
1. INSPECT 2WD 4HI SHIFT
(a) Turn the ignition switch to the ON position.
(b) Check that the 4HI indicator lights come on when the
2WD/4HI switch is in the ON position.
ON
(c) Check that the 4HI indicator lights go off when the
2WD/4HI switch is in the OFF position.
HINT:
F19330
S If the light does not come on, even though the switch has
been turned ON, the vehicle should be moved back and
forth.
S If switching is not completed after 3 seconds of shift op-
eration, the 4HI indicator light will flash.
2. INSPECT 4HI 4LO SHIFT
(a) Turn the ignition switch to the ON position.
(b) Shift the transmission shift lever in the N position.
(c) Turn the 2WD/4HI switch ON.
(d) Check that the 4LO indicator lights come on and the 4HI
4LO Switch
indicator lights go off when the 4LO switch is in the ON
position.
(e) Check that the 4LO indicator lights go off and the 4HI indi-
ON cator lights come on when pushing the 4LO switch once.
HINT:
S Inspection should be performed with the vehicle stopped,
and transmission shift lever in the N position.
F19331 S If switching is not completed after 3 seconds of shift op-
eration, the 4LO indicator light will flash.

Center Integration Panel Assembly 3. INSPECT 2WD/4HI AND 4LO SWITCH CONTINUITY
(a) Remove the center integration panel assembly
(See page BO-111).
(b) Measure the resistance between the terminals as shown.
2WD/4HI switch
Standard:
Switch position Tester connection Specified condition
OFF 1-5 10 k or higher
ON 1-5 Below 1
4LO switch
Standard:
1
Switch position Tester connection Specified condition
4 OFF 1-4 10 k or higher
5 ON 1-4 Below 1
If the result is not as specified, replace the center integration
panel assembly (See page BO-111).

4. INSPECT ACTUATOR RESISTANCE
Actuator side:
(a) Using an ohmmeter, measure the resistance between ter-
minals 1 and 2.
Standard resistance: 0.3 to 100
(b) Using an ohmmeter, measure the resistance between ter-
minals 1 or 2 and body ground.
Standard resistance: 0.5 M or higher
If the result is not as specified, replace the actuator assembly.

5. INSPECT ACTUATOR OPERATION
(a) 2WD 4HI shift:
Connect lines via a relay as shown in the illustration, then
check that the actuator fork shaft moves from the 2WD to
4HI position.

6. INSPECT LIMIT SWITCH CONTINUITY
Actuator side:
(a) Start the engine and raise the vehicle.
(b) With the actuator connector connected, shift the transfer
shift lever and after checking the operating sound, dis-
connect the connector and measure the resistance be-
tween each terminal.
HINT:
When shifting the actuator fork shaft, connect the connectors.
