DTC Descriptor
B0099 00
- Deployment Commanded Circuit




Circuit/System Description

The pedestrian impact detection system (PIDS) senses and discriminates vehicle impacts and deploys the pedestrian hood hinge actuators in a timely manner to protect vulnerable pedestrians. The discrimination sensor provides discrete force information to the pedestrian impact detection system (PIDS) module. The PIDS 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 hood actuators deploy only when a valid signal whose energy is capable of triggering deployment of the hood is present. During a frontal pedestrian impact of sufficient force, the PIDS module will allow current to flow through the deployment loop in order to deploy the hood hinge actuator. The PIDS module provides a minimum of 1.2 amps and a maximum of 1.95 amps of current for a minimum of 2 ms when an actuator deployment is commanded. The PIDS module performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity. The PIDS module sets this DTC in the current ignition cycle when a hood hinge actuator deployment has been commanded. After a deployment, the hood hinge actuators and the PIDS module need to be replaced.


Conditions for Running the DTC

Ignition voltage is between 9-16 volts.


Conditions for Setting the DTC

* The PIDS module detects a frontal impact to warrant deployment of the hood hinge actuators.
* The PIDS module provides a minimum of 1.2 amps and a maximum of 1.95 amps of current for a minimum of 2 ms to command deployment of the hood hinge actuators



Action Taken When the DTC Sets

* The PIDS module commands the DIC to display the message 'Reset Hood See Owners Manual' for the following two ignition cycles.
* The PIDS module commands the DIC to display the message 'Service Pedestrian Protection System' at the third ignition cycle after the hood hinge actuators have been deployed until service is performed .



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

Ignition ON, verify DTC B0099 is not set.

If DTC is set, replace the PIDS module and the hood hinge actuators.
