    Standard:
    0.1 to 100 Ω

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

    Standard:
    5 MΩ or more
    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 according to the value(s) in the table below.

      Standard Resistance:
      Tester Connection
      		Measurement Condition
      		Specified Condition
      3 - 4
      		Battery positive (+) → Terminal 1
      Battery negative (-) → Terminal 2
      		Below 1 Ω
      3 - 4
      		Battery positive (+) → Terminal 2
      Battery negative (-) → Terminal 1
      		10 kΩ or higher
      4 - 5
      		Battery positive (+) → Terminal 1
      Battery negative (-) → Terminal 2
      		Below 1 Ω
      4 - 5
      		Battery positive (+) → Terminal 2
      Battery negative (-) → Terminal 1
      		10 kΩ or higher
      4 - 6
      		Battery positive (+) → Terminal 1
      Battery negative (-) → Terminal 2
      		Below 1 Ω
      4 - 6
      		Battery positive (+) → Terminal 2
      Battery negative (-) → Terminal 1
      		10 kΩ or higher
      If the result is not as specified, replace the actuator.

    2. Check the actuator status.

      OK:
      Measurement Condition
      		Specified Condition
      Battery positive (+) → Terminal 1
      Battery negative (-) → Terminal 2
      		2WD → 4WD
      Battery positive (+) → Terminal 2
      Battery negative (-) → Terminal 1
      		4WD → 2WD
      If the result is not as specified, replace the actuator.
