HORNS OPERATIONAL DESCRIPTION
Operational Description
The command for the horns is supplied by the steering wheel node control unit M093 to the body computer node M001. The signal travels via the CAN which connects the two control units.
The steering wheel node control unit M093 receives a supply (pin 5 connector A) through the line protected by fuse F11, located in the body computer node M001; it receives a supply via the CAN (pin 6 connector A) from the line protected by fuse F16, located in the body computer node M001.
The signal is sent, via the CAN, to the engine compartment junction unit which supplies the horns P005 (pin 7 connector H of B001) via the line protected by fuse F13. The supply line is managed by a specific relay, located in the engine compartment junction unit B001.
