Operating procedure

Basic conditions:

The transmitter key (A8/1) in the electronic ignition switch of the electronic ignition switch control module (N73) is set to position 2 "circuit 15 ON".
The electronic ignition switch control module (N73) actuates over the CAN interior the rear SAM control module with fuse and relay module (N10/2) with the "circuit 15 ON" signal.
The gearshift lever is set to stage "R".

The automated manual transmission control module (N15/6) actuates the electronic ignition switch control module (N73) over the CAN interior with the "reverse gear ON" signal.
The electronic ignition switch control module (N73) sends the signal over the CAN interior to the rear SAM control module with fuse and relay module (N10/2).
The rear SAM control module with fuse and relay module actuates the backup lamps (E3e3 and E4e3) in the left taillamp (E3) and right taillamp (E4).
For a trailer hitch the "backup lamp ON" signal is also sent over the CAN interior to the trailer recognition control module (N28/1) and voltage applied to the trailer backup lamps to the trailer hitch socket, 13-pin (X58).
