Bottom motor and bottom ignition box
The bus system is equipped with a 6-pol Mini-Fit plug system.
In the bus system the individual components have individual addresses. Each address only exists once in a unit.
On units 201 and 202 the bottom fan motor and the bottom ignition box are identied by a jumper. This jumper
is part of the control harness.
The main pcb sends the action command via the bus cable. Additionally the pcb receives information from the
individual components via the same bus ( e.g. rpm).
In case the component does not respond to the bus signal an error Service 34.x will be shown.
The two bus connections on the motor and ignition box are equal and can be chosen freely.
Error 34.x: failure of BUS communication between PCB and other BUS components. Check the power sup-
ply, the LED and the BUS cable on the components. When the error number changes aer changing
the bus cable sequence, one of the bus cables is defective.
A combination of errors is possible: e.g. 34.10 No bus communication with bottom motor and bottom
ignition box. Please refer to fault tree!
Please apply contact grease 9003.0219 to bus cable plugs
Keep the bus cable away from hot surfaces. In case of an internal bus short circuit pcb, motor or ignition box
can be damaged!
Note: SCC Index E-G has an additional I/O pcb (address 1) connected to the bus system. In that unit the top
motor has BUS number 2, the bottom motor number 4 etc.
