16-78 ELECTRICAL SYSTEM
Actuator Control System
•
Turn ON the ignition switch.
•
Shift to the 2WD position.
•
Measure the controller output voltage for the 2WD/4WD
actuator until the actuator stops.
Controller Output Voltage (to 2WD/4WD actuator)
Standard:
5 ∼ 12 V
If the reading is not standard, check the 2WD/4WD shift
switch.
If the 2WD/4WD shift switch is normal, replace the actu-
ator controller unit.
Check 7. Forward/Reverse Detecting Sensor Inspec-
tion
•
Remove the left footboard (see Left Footboard Removal
in the Frame chapter).
•
Disconnect forward/reverse detecting sensor lead con-
nector [A].
•
Measure the forward/reverse detecting sensor resis-
tance.
○
Connect the hand tester between the BK lead and the W
lead.
○
Set the tester to the × kΩ range.
Special Tool - Hand Tester: 57001-1394
Forward/Reverse Detecting Sensor Resistance
Standard: 1.2 ∼ 1.6 kΩ
If the reading is not within the specified range, replace the
forward/reverse detecting sensor.
•
Using the highest resistance, measure the resistance be-
tween forward/reverse detecting sensor leads and chas-
sis ground.
If the tester reading is less than infinity (∞) indicates a
short, replace the forward/reverse detecting sensor.
Check 8. Indicator Light (LCD) Inspection
•
Refer to Check 7: 2WD/4WD Indicator Lights Check in
Multifunction Meter Unit Inspection.
