Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the left active hood hinge actuator.
  2. Ignition ON, test for less than 1 volt between the high control circuit terminal A and ground.
    • If greater than the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the pedestrian impact detection module.
  3. Test for less than 1 volt between the low control circuit terminal B and ground.
    • If greater than the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the pedestrian impact detection module.
  4. Ignition OFF, test for infinite resistance between the high control circuit terminal A and ground.
    • If not the specified value, test the circuit for a short to ground. If the circuit tests normal, replace the pedestrian impact detection module.
  5. Test for infinite resistance between the low control circuit terminal B and ground.
    • If not the specified value, test the circuit for a short to ground. If the circuit tests normal, replace the pedestrian impact detection module.
  6. Test for less then 1 ohm between the high control circuit terminal A and ground.
    • If not within the specified range, test the circuit for an open/high resistance.
  7. Test for less then 1 ohm between the low control circuit terminal B and ground.
    • If not within the specified range, test the circuit for an open/high resistance.
  8. If all circuits test normal, replace the left active hood hinge actuator.
