Restraint Control Module (RCM)
WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The RCM is on the international standards organization (ISO) 9141 communication network. The RCM controls the deployment of the air bags based on sensor input. The ISO 9141 communication network does not function if the wire is shorted to ground or battery voltage. Check the network circuit between the RCM C2041a and the DLC C251. Total resistance value must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the ISO 9141 communication network, damage to the DLC C251, damage to the RCM C2041a, or a problem in the in-line connector.
