BDM100 Module 

 

Interconnections for Marelli ECUs 

 

Pict. A: The main connector of the Marelli ECU 

 
In case of a Marelli 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, it is already connected to the 
battery! 

Please, ensure that the ignition is 
switched off at beginning! 

 
 
Before you can start to read out or program 
a Marelli ECU, you must solder out the zero-
ohm resistor witch is next pin19 of the 
component with SO28 package in the  cor-
ner of the ECU board (Pict. B). 
 
There is also another Type of the Marelli 
MJD- ECU which has another PCB-layout 
and some other components. There the 
zero-ohm resistor is placed near the flash-
EPROM (Pict. C). 
 
Don’t forget to solder the zero-ohm resistor 
on its place again when the work with the 
BDM equipment is done. 

 

 

Pict. B: The location of the zero-ohm resistor witch 
will be out-soldered. 

Pict. C: On this Marelli MJD-ECU (with another 
PCB-design) the resistor is already out-soldered.
