Interconnections for Siemens SID203 ECUs
Pict.A: The connections for power and ignition for the SID203 ECU are the same as on the
Siemens SID201 ECU.
In case of the Siemens SID203 ECU the
power distribution is provided by the pins of
the main connector marked in picture 16a.
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. If the length of the spring contact
pins is not long enough, pull the spring
contact pins up to the first rast 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 apply 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

of the Siemens SID203 ECU.
Don't forget to close the jumper! For the BDM-
module this is necessary to recognize the ECU.
