Interconnections for Delphi ECUs
Pict. A: The main connector of the Delphi ECU
In case of a Delphi ECU the power
distribution can not provided by special pads
of the BDM port.
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 while plugging the con-
nections!
Now place the BDM142 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.
The tips of the spring contact probes should
reach a spring travel of 2mm minimum for
best contact conditions.
If you then applying power to the main
connector of the ECU the red LED of the
BDM142 probe lights up to indicate that the
logic on the board is supplied with the
required voltage.
