Tacoma 4WD V6-3.4L (5VZ-FE) (1995)
Transfer Case Actuator: Testing and Inspection
2-4 Actuator Assembly Connector
1. Inspect resistance.
a. Using an ohmmeter, measure the resistance between terminals 2 and 3.
Standard Resistance: 0.3 - 100 ohms
b. Using an ohmmeter, measure the resistance between terminals 2 or 3 and body ground.
Standard Resistance: More than 0.5 M ohms
If resistance value is not as specified, replace the actuator assembly.
2. Inspect operation.
a. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 3, then check that the actuator fork shaft
moves to 2WD position.
b. Connect the positive (+) lead from the battery to terminal 3 and the negative (-) lead to terminal 2, then check that the actuator fork shaft
moves to 4WD position.
If operation is not as specified, replace the actuator assembly.
3. Inspect limit switch continuity.
a. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 3.
b. Connect the positive (+) lead from the ohmmeter to terminal 5 and the negative (-) lead to terminal 4.
c. Check that there is continuity between terminals 4 and 5.
