Interconnections for Siemens MS45 ECUs
+12Vcc (1-7)
GND (1-4)
+12Vcc (4-26)
Pict.A: The main connector of the MS45 ECU.
In case of the Siemens MS45 ECU the
power distribution is provided by the pins of
the main connector marked in picture 19.
Use separate wires to connect GND and
+12Vcc to the pins of the main connector
shown in picture A.
The voltage is provided by a stabilized
power supply or by the main connector of
the ECU at the cable harness of the car.
! Warning ! Please always remind, if the
open ECU is connected to the cable
harness of the car, it is already connected to
the battery!
Please, ensure that the ignition is
switched off at beginning!
Now place the BDM141 probe into the
positioning frame and carefully put the tips
of the spring contact probes on the pads on
the board as shown in picture C.
If the length of the spring contact pins
should be to short, pull the spring contact
pins up to the first rest position from the
receptacles.
The tips of the spring contact probes should
reach a spring travel of 1mm minimum for
best contact conditions.
If you then applying power to the main
connector of the ECU the red LED of the
BDM141 probe lights up to indicate that the
logic on the board is supplied with the
required voltage
The BDM100 module is now operational.
