Actuator: Testing and Inspection
DIFFERENTIAL: AUTOMATIC DISCONNECTING DIFFERENTIAL ACTUATOR:
INSPECTION
1. INSPECT AUTOMATIC DISCONNECTING DIFFERENTIAL ACTUATOR
NOTE: When inspecting the actuator, make sure to operate it with the lines connected via a relay. If the lines are not connected via a relay and
battery voltage is directly applied to the actuator, the actuator will be damaged.
HINT: When inspecting the operation described above, use the fuel pump control relay.
(a) Check Free to Lock switch.
(1) Connect lines via a relay as shown in the illustration, then check that the actuator fork moves from the Free to Lock position.
(2) After the Free to Lock switch is complete, inspect the A.D.D. detection switch and limit switch
Standard resistance:
If there is malfunction, replace the A.D.D. actuator. If the A.D.D. actuator is normal, replace the 4WD control ECU.
(b) Check Lock to Free switch.
(1) Connect lines via a relay as shown in the illustration, then check that the actuator fork moves from the Lock to Free position.
(2) After the Lock to Free switch is complete, inspect the A.D.D. detection switch and limit switch.
Standard resistance:
If there is malfunction, replace the A.D.D. actuator. If the A.D.D. actuator is normal, replace the 4WD control ECU.
