ESP WARNING LIGHT IN CONTROL PANEL ON

The Brake Node sends a FAULT/INTERVENTION message via the C-CAN network to the Body Computer that makes it available through the Gateway, via the B-CAN network, to the Instrument Panel Node. The latter turns on the warning light and displays a FAULT/INTERVENTION message on the active matrix.
