Default I/O diagram of the brake control unit
The diagram below shows the default I/O connections on the brake control unit, and describes
the use of the signals/connections. Under normal circumstances, the factory-made wiring
should not be changed.
The wire size accepted by all screw terminals (for both stranded and solid wire) is 0.5 …
2.5 mm
2
(24…12 AWG). The torque is 0.5 N·m (5 lbf·in).
