Network Message Chart - Indicators and Reconfigurable Telltales (RTTs)
The telltales and Reconfigurable Telltales (RTTs) are illuminated or displayed in the IPC when the IPC receives messaged inputs from other modules on the CAN, due to system faults detected, system status changes or for driver information. The IPC communicates on the HS-CAN3. If the originating module communicates on a network other than the HS-CAN3, the messaged signals are sent to the GWM first, then to the IPC.
