  1. Normal Operation and Fault Conditions 

    See Seatbelt Warning RTT Indicator. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .

    If the driver seatbelt buckle status or passenger seatbelt buckle status message is missing for less than 5 seconds, the IPC defaults the seatbelt warning RTT indicator to its last indication state (on or off), based upon the last message received.

    If the driver seatbelt buckle status or passenger seatbelt buckle status message is missing for 5 seconds or longer, the IPC defaults the seatbelt warning RTT indicator off.
