Action Taken When the DTC Sets

* The pedestrian impact detection module commands the DIC to display Service Pedestrian Protection System.

* The pedestrian impact detection module stores DTC in memory.

Conditions for Clearing the DTC

* The condition responsible for setting the DTC no longer exists.

* A history DTC will clear once 40 malfunction-free ignition cycles have occurred.

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.

瀚慖f 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.

瀚慖f 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.

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 left active hood hinge actuator.
