ABS FAILURE WARNING LIGHT ON
The brakes node sends the ABS warning light on message via the C-CAN network to the body computer which, through the gateway, makes it available via the B-CAN network to the instrument panel node.
Warning: If there are faults at the C-CAN, the control unit failure warning lights will light up. The CAN INFORMATION CHECK is designed precisely for this purpose
