1. INSPECT DIFFERENTIAL VACUUM ACTUATOR ASSEMBLY


F043678E04

  1. Measure the resistance between terminals 1 and 2.

    Standard resistance:
    0.1 to 100 Ω

  1. Measure the resistance between terminal 1 or 2 and body ground.

    Standard:
    5 MΩ or more

    1. If the result is not as specified, replace the differential vacuum actuator.

  1. Check the actuator using one of the following methods.

    1. Measure the resistance of the actuator.

      Standard resistance:

      Tester Connection
      		Measurement Condition
      		Specified Condition
      3 to 4
      		Battery positive (+) → Terminal 1
      Battery negative (-) → Terminal 2
      		Below 1 Ω
      3 to 4
      		Battery positive (+) → Terminal 2
      Battery negative (-) → Terminal 1
      		10 kΩ or more
      4 to 5
      		Battery positive (+) → Terminal 1
      Battery negative (-) → Terminal 2
      		Below 1 Ω
      4 to 5
      		Battery positive (+) → Terminal 2
      Battery negative (-) → Terminal 1
      		10 kΩ or more
      4 to 6
      		Battery positive (+) → Terminal 1
      Battery negative (-) → Terminal 2
      		Below 1 Ω
      4 to 6
      		Battery positive (+) → Terminal 2
      Battery negative (-) → Terminal 1
      		10 kΩ or more

      1. If the result is not as specified, replace the actuator.

    2. Check the actuator status.

      Actuator operation:
      Measurement Condition
      		Specified Condition
      Battery positive (+) → Terminal 1
      Battery negative (-) → Terminal 2
      		2WD → 4WD
      Battery positive (+) → Terminal 2
      Battery negative (-) → Terminal 1
      		4WD → 2WD

      1. If the result is not as specified, replace the actuator.
