瀚慖f 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.

瀚慖f 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.

瀚慖f 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.

瀚慖f not within the specified range, test the circuit for an open/high resistance.

8. If all circuits test normal, replace the right active hood hinge actuator.
