B009B 02

The pedestrian impact detection module deployment loop resistance leakage is less than 3.5 k ohms for 2.5 seconds.

B009B 04

The pedestrian impact detection module deployment loop resistance is greater than 7.2 ohms for 2.5 seconds.

B009B 0D

The pedestrian impact detection module deployment loop resistance is greater than 3.1 ohms for 2.5 seconds.

B009B 0E

The pedestrian impact detection module deployment loop resistance is less than 1.6 ohms for 2.5 seconds.

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 right 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.
