Normal Operation - Restraints Control Module (RCM)
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.
