17-80 ELECTRICAL SYSTEM
Actuator Control System
•
Support the vehicle on a stand or a jack so that the wheels
are off the ground.
•
Connect:
Controller Connector [A]
Hand Tester [B] (range: DC 25 V)
Tester (+ ) → Connector (W/R) Terminal [15]
Tester (–) → Connector (BK/Y) Terminal [10]
○
Install the needle adapters on the tester leads.
Special Tools - Hand Tester: 57001-1394
Needle Adapter Set: 57001-1457
•
Turn ON the ignition switch.
•
Spin a rear wheel as forward rotation.
•
After the wheels stop and one second elapses, turn O FF
the ignition switch.
•
After two seconds elapses, m easure the controller output
voltage for the engine brake actuator until the actuator
stops.
Controller O utput Voltage (to engine brake actuator)
Standard:
5 ∼ 12 V
If the reading is not standard, check the forward/reverse
detecting sensor.
If the forward/reverse detecting sensor is normal, replace
the actuator controller unit.
•
Support the vehicle on a stand or a jack so that the wheels
are off the ground.
•
Run the engine and shift to the 4WD position.
•
Stop the engine and turn OFF the ignition switch.
•
Connect:
Controller Connector [A]
Hand Tester [B] (range: DC 25 V)
Tester (+ ) → Connector (W/Y) Terminal [13]
Tester (–) → Connector (BK/Y) Terminal [10]
○
Install the needle adapters on the tester leads.
Special Tools - Hand Tester: 57001-1394

•
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 2W D/4WD shift
switch.
If the 2WD/4WD shift switch is normal, replace the actu-
ator controller unit.
