Normal Operation - Restraints Control Module (RCM)
WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The Restraints Control Module (RCM) continuously monitors the input voltage for correct operation. If the RCM detects input voltage below 9.5 volts, it stores DTC U3003:16 in memory. If the RCM detects input voltage above 16 volts, it stores DTC U3003:17 in memory. If the RCM sets DTC U3003:16 or U3003:17, it sends a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
