Fire Suppression Module (FSM)

WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

The FSM (if equipped) is connected to the CAN and the international standards organization (ISO) 9141 communications network. The fire suppression system is designed to help reduce the risk of fire in high speed rear impacts. The fire suppression system deploys chemicals designed to suppress the spread of fire or potentially extinguish a fire, thereby providing more time for occupants to escape from a crashed vehicle.

Check the CAN and ISO 9141 communications network circuits between the FSM C3281a and the DLC C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the CAN or ISO 9141 communications network, damage to the DLC C251, damage to the FSM C3281a, or a problem in the in-line connector.
