Interconnections for Siemens SIM266 ECUs
Pict. A: The main connector of the SIM266 ECUs.
On the Siemens SIM266 ECU the power
distribution is provided by the pins of the
main connector as shown in picture A.
Use separate wires to connect GND and
+12Vcc to the pins of the main connector
shown in picture.A
Although the BDM pads don’t appear in a
well known arrangement on the Siemens
SIM266 ECU board, the BDM145 probe
provides a solution to contact the required
BDM pads which are scattered all over the
top side of the ECU board.
After removing the back plate of the ECU
you will look for the PCP area the required
pads are located in (as shown in Pict. B).
Use a support padding with 10mm thickness
and 100mm x 150mm in size under the ECU
to get a horizontally alignment of the ECU
board with the positioning frame base plate.
Now place the BDM145 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.
Use the representation in Pict. 26 for orien-
tation and make sure that the spring con-
tact probe hits centrically the correct pads
before you switch on the power.
Pict
. B: This are the pads which are required for
the BDM interface.
Pict. C: The tips of the spring contact probes
should reach a spring travel of 2mm minimum for
best contact conditions
