BDM100 Module on ECUs for Trucks
Connecting to BOSCH EDC7 ECUs
On the EDC7 board the BDM port pads are
located very near the MPC555 processor.
On Picture 3 the orientation of the Pads
arrangement is shown.
Note that at all only 10 pads of the total 14
are used for the EDC7 programming port.
The pads with the numbers 2,3,13 and 14
are not used.
Ensure that the pads are clean and free of
remaining flux agent.
On the EDC7 board the required pads are
also located in the very middle of the whole Pict. 3: This is the characteristic arrangement of
board. Because of this you must not place the Bosch BDM pads.
the BDM143 probe completely into the
guide slot of the positioning frame (as
shown in picture 4)
Now connect the BDM143 probe to the
BDM100 module
Ensure that the switch of the BDM143 probe
is in its ‘OFF’-position.
Carefully put the tips of the spring contact
probes on the pads on the board as shown
in picture 4a.
It is recommended to use an isolation foil, to
avoid that the arm of the positioning frame
produces short-circuits between larger
components on the top side of the board.
The power for the board will applied over

the power jack on the BDM143 adapter.
If you prefer to use the other BDM port on
the side of the ECU where the main
connectors were mounted, a BDM141
adapter is required (Pict. 5).
In that case the power to the EDC7 board is
provided by some pins of the main
connectors:
There are several versions of the EDC7
ECU. All of them are equiped with the
same connectors, but the pins for GND,
battery and ignition are on differnt pins,
depending of the version of the EDC7
ECU!

Connection to MOTOROLA EDC S6 ECUs
The MOTOROLA EDC S6 needs a +24V
power supply.
Connect that to the contacts No. 1,3 and
6 in the upper chamber of the main
connector "B".
The GND connection is etablished by
contact No. 2 in the same chamber of the
same connector "B" (picture 6).
The required BDM-pads are located near
the processor at the boarder of the board.
The position of Pin1 is shown on picture 7
The pin-out of the pad array matches the
Pict. 6: The main connectors "A" and "B" of the
MOTOROLA BDM standard pin-out.

Connection to MOTOROLA / Cummins CM850 ECUs
The MOTOROLA CM850 ECU needs
some modifications and is pretty hard to
do.
On the 4-pin power connector, connect
GND to contact No. 1.and connect
+12Vcc to contact No. 3.
On the 50-pin OEM connector, also
connect +12Vcc to pin No. 39 (Ignition).
Pict. 7a: The location of the BDM-pads on the board.
The contacts for +12Vcc, GND, Ign on
the CM850 ECU.
The required BDM-pads are located near
the boarder of the board (Picture 7a):
The position of Pin1 is shown on picture
7a
The pin-out of the pad array matches the
MOTOROLA BDM standard pin-out.
For making the CM850 ECU readable, a
pin of the QFP-chip shown in picture 7b
must be unsoldered.
Pict. 7b: That pin must not connected to HRES- .
No matter what number that pin has, it is
connected to the HRES- pad of the BDMport (please refer to the chapter Pin Out
BDM Module ).
Use an ohmmeter or a continuity tester to
estiimate that pin.
For erasing and programming the ECU, a
22-ohms resistor must be soldered
between two contacts of the Transistor
shown in picture 7c.
Don't forget to unsolder the resistor
and to solder the pin of the QFP-chip
again after programming.

Connection to TRW EMS2 ECUs
The TRW EMS2 ECU has two main
connectors "A" and "B".
This marking is also present in the material of the mounting plate.
The +24V power supply is applied to the
pins No. 57 and / or No. 60 of connector
"B".
The GND connection is made to the pins
No. 58,59 and / or No. 61.
It is enough to use only one pin for GND
and another one for +24V. So the power
connection can be done with a two-wire
cable.
The position of the required pins should
be obvious regarding picture 8.
For programming purposes, this ECU
does not require an extra wire for an
"ignition-on" signal.
Pict. 8: the main connectors of the TRW EMS2 ECU.
The required pads for programming are
located between an S-RAM component
and the EEPROM in a SO8 package as
shown in picture 9.
The BDM148 probe in conjunction with
the BDM140 positioning frame makes it
possible to program this ECU without
soldering.

Connection to John Deere L14 ECUs
Pict. 10: The main connector of the John Deere L14 ECU.
On the John Deere L14 ECU the
connections are made to the middle
chamber of the main connector.
The pins in that chamber are arranged in
four row rows (1-4) and the rows are
numbered alphabeticaly from "A" to "M".
Where to connect power to the main
connector, you please infer from pict. 10.
The BDM pads shown in Picture 11 have
a Motorola standard pin out.
At this case a BDM142 probe is used to
contact the BDM pads.
Pict. 11: The BDM pads on the L14 board.
Please note, that the BDM142 probe must
inserted 180° turned into the arm of the
positioning frame as shown in picture 12 !
That may be pretty hard to justify but
currently the only way to program the L14
ECU without soldering.
Pict. 12: To connect the BDM pads, currently a
BDM142 probe is used.

Connection to Delphi /DAF ECUs
On the Delphi / DAF ECU there are three
main connectors named in the following
sequence: "A;C;B" like shown in Pict. 13.
For applying power to the ECU, the
connector "C" contains all required
contacts.
A +24VDC power supply connected to
the pins C41 and C62 powers the ECU.
GND is connected to pin C57.
The position of the pins are also shown in
picture 13.
Pict. 13: The main connectors on the Delphi /DAF
ECU.
Picture 14 shows the 10-pin header on
the board of the Delphi / DAF ECU.
If you don't like to solder a 10-pin header,
you also can use a BDM149 probe for
programming this ECU.
Pict. 14: There the 10-pin header for the BDM-Port is
located.

Connection to Delphi / ISUZU ECUs
On the Delphi ECU for ISUZU there are
two Connectors named J1 and J2.
The large contact pin of J1 (J1,73) is
used for the GND connection
The connection for Ubat power supply
and the IGN signal are made to the
contact pins J2,73 and J2,72 of the J2
connector as shown in pict. 15.
Pict. 15: The main connectors on the Delphi / ISUZU
ECU are named J1 (grey) and J2 (black).
When the rear plate of the ECU is
removed, you should recognize a 10- pad
array located at the edge of the board.
This is the BDM-port. On pict. 16 is also
marked the location of pin 1.
You best use a BDM149 probe to contact
this pad array.

The Alignment of the BDM-Port Pads
On the most ECU Boards the location of
pin 1 of the BDM-port pads are not
marked in any way. This application
note will demonstrate how you can
estimate the location of Pin1 of the
BDM-port pads in the very most cases.
The figure on the right shows the
Motorola (TM) standard pin out of the
BDM-port:

Fig. 1: This is the standard BDM-port pin out.
Regarding the pin out of the standard
BDM-port it is obvious that two of them
are grounded. These are the pins 3 and
5. So the pin 1 is above them.
Which of the pads are grounded you can
find out simply using an ohmmeter or a
diode-tester.
Finally let us demonstrate this again in
the next three steps using a SMD
footprint of the BDM-port pads:
1st. step:

Pin Out BDM100 Module
Picture 37 shows the pinout of the 10way
pin header located on the back of the
BDM100 Module.
This pinout appropriates the standard
BDM port pinout.
On ECUs equiped with a 10way BDMport the interconnection can made by
using a simple 10way flat- wire cable. In
this case the location of pin 1 of the BDMport on the ECU board should be known.
Pict. 40: The pinout of the 10way pin header
Pin Out BOSCH System Programming Pads
The pad arrangement of the BOSCH
ECUs differs from the MOTOROLA
standard.
The 12Vcc clamp voltage from the battery
and also the !2Vcc from the Ignition or
wake up circuit are present in that pad
array.
Picture 38 shows which signals and
voltages were assigned to the pads.
Please consider that in early EDC16
ECUs the 3.3V pad is driven by a 5V
circuit.
