DTC B2800-00: MM CAN Bus Off Error: General Description

The Head Up Display (HUD) is a safety and convenience device that the driver can see information much faster, without having to take eyes off the road. The HUD ECU receives C-CAN (vehicle speed/Smart Cruise Control (SCC)/ECO/illumination) information and B-CAN (seat belt/high beam/fuel level warning lamp/auto light sensor) information from the vehicle systems. It displays directly the information on the combiner head up displays.
