Diagnostic Fault Information
Circuit/System Description
The pedestrian impact detection system senses and discriminates vehicle impacts and deploys the pedestrian hood hinge actuators in a timely manner to protect vulnerable pedestrians. The safing sensor provides vehicle acceleration information to the pedestrian impact detection module. The pedestrian impact detection module uses vehicle acceleration information from the safing sensor and force information from the discrimination sensor to determine those events when the deployment of the hood hinge actuator is expected. The pedestrian impact detection module provides a two wire current loop interface to the safing sensor. The pedestrian impact detection module also provides power and ground to the safing sensor over the same two wire discrete interface. The pedestrian impact detection module monitors the safing sensor for any system malfunction and when a malfunction is detected, a DTC will be stored in non volatile memory.
Conditions for Running the DTC
Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC
B009D 01
The safing sensor voltage is greater than 3.2 V and the safing sensor voltage is not supplied by the pedestrian impact detection module.
B009D 02
The safing sensor voltage is less than 3.5 V and the safing sensor voltage is being supplied by the pedestrian impact detection module.
B009D 08
The safing sensor high and/or low circuit is open. An open circuit indicates no new data received.
B009D 39
The safing sensor sends an error message or invalid data to the pedestrian impact detection module.
B009D 3A
Invalid safing sensor ID data received by the pedestrian impact detection module
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 rear upper beam sensor and the harness connector at the pedestrian impact detection module.
2. Test for infinite resistance between the sensor signal circuit terminal 1 and ground.
• If less than infinite resistance, test the circuit for a short to ground.
3. Ignition ON, test for less than 1 volt between the sensor signal circuit terminal 1 and ground.
• If greater than the specified range, test the circuit for a short to voltage.
4. Test for less than 1 volt between the sensor low reference circuit terminal 2 and ground.
• If greater than the specified range, test the circuit for a short to voltage.
5. Test for less than 1 ohm between the sensor low reference circuit terminal 2 and the pedestrian impact detection module terminal 31.
• If greater than the specified value, test the circuit for an open/high resistance. If the circuit tests normal, replace the rear upper beam sensor.
6. Test for less than 1 ohm between the sensor signal circuit terminal 1 and the pedestrian impact detection module terminal 30.
• If greater than the specified value, test the circuit for an open/high resistance. If the circuit tests normal, replace the rear upper beam sensor.
7. If all circuits test normal, replace the rear upper beam sensor.
8. With a scan tool, clear DTCs.
9. Verify DTC B009D is not set.
• If DTC is set, replace the pedestrian impact detection module.
