REAR FOGLAMPS OPERATIONAL DESCRIPTION

Operational Description

The command to switch on the rear fog lamps 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.

Having received the command, the body computer node M001 energizes the relay coil thereby providing a supply via the line protected by fuse F1 (pin 4 connector H) to switch on the lamps located in the left F030 and right F031 light clusters.

The warning light is switched on by the milometer warning lights node M140 which communicates with the instrument panel E050 and the body computer node M001 via the CAN.

The instrument panel E050 and the milometer warning lights node M140 receive a supply via the CAN (pin 13 of E50 and pin 4 of M140) through the line protected by fuse F24 of the body computer M001.
