JBE: Junction Box Electronics
The junction box electronics (JBE) deliver the signal as to whether the luggage compartment lid is closed (bus signal).
The power distribution box in the junction box supplies the soft top module (CVM) with electrical power (terminal 30g). In addition, the CVM is supplied by terminal 15 from the Car Access System (CAS). If, for example, the power supply from the junction box is interrupted, adequate communication with the BMW diagnosis system is still possible.
