Restraint Control Module (RCM)
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The RCM uses the high speed CAN for communication with the diagnostic tool and other modules on the high speed CAN. The RCM controls the deployment of the air bags based on sensor input.
Check the high speed CAN circuits between the RCM C310b 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 high speed CAN, damage to the DLC C251, damage to the RCM C310b, or a problem in the in-line connector.
