198001842 - K068 ESP WARNING LIGHT ON

The Brake Node sends the ABS warning light on message via the C-CAN to the Body Computer which makes it available via the gateway to the Instrument Panel Node through the B-CAN.
If there are problems in the C-CAN, the control unit warning lights for this network will light up. The "CAN INFORMATION" check is designed for this eventuality
