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 will store DTC U3003:16 in memory. If the RCM  detects input voltage above 20 volts, it will store DTC U3003:17 in memory. If the RCM  sets DTC U3003:16 or U3003:17, it will send a message to the Instrument Cluster (IC) module to illuminate the air bag warning indicator.
