The RCM communicates with other modules on the HS-CAN. When the ignition is first turned ON, the RCM will attempt to initialize itself on the HS-CAN.
If the RCM cannot initialize on the HS-CAN, or if it cannot communicate with any other module, the RCM stores DTC U0001:88 or U1A14:55 in memory and sends a message to the IPC to illuminate the airbag warning indicator.
