Restraints Control Module (RCM)

The RCM is on the ISO 9141 communication network. The RCM controls the deployment of the air bags based on sensor input. Check the ISO 9141 network circuit between the RCM C2041 and the DLC C251. The 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 C2041, or a problem in the in-line connector.
