What is BDM?

BDM is an acronym for Background Debug Mode, an interface designed by the Motorola company, widely used in automotive industry, present on modern ECUs. Not all ECUs are capable of interfacing through the BDM – see Appendix for the list of ECUs that support the BDM interface.

What is Adapter?

ADAPTER is an electronic circuit board designed for a certain ECU (manufacturer), with pogo pins and a 10-pin

IDC connector for interfacing the multiplexer board.

What is a BDM Adapter?

BDM adapter is an electronic circuit intended for BDM operation on supported ECU. The adapter provides pogo pin based connectors for interfacing the ECU BDM connector. Interfacing the supported tool is made by the use of intermediate circuit board (multiplexer) that connects to the adapter over the MUX connector and to the tool over the desired tool connector (FGTECH, XPROG, BDM100,Dimsport, KTM100, Kess V2 & KTAG, etc.)

How to use a BDM probe adapter with KTAG/KESS/KTM100/Dimsport?

1.    Open the ECU

at least one part of the casing (top or bottom) needs to be removed
refer to other sources (Internet) to get information on which part needs removing on your ECU

2. Locate the ECU BDM connector

usually a set of 10 – 12 pads in two rows (depending on the ECU)
pads may be 2.54 mm or 1.27 mm apart (depending on the ECU)
rows may be 2.54 mm or 5.08 mm apart (depending on the ECU)
if the ECU BDM connector can not be located, chances are that the BDM pads are scattered

all over the ECU PCB in which case you can not use the adapter directly – nevertheless it is possible to manually route the adapter BDM signals to the ECU BDM pads (only for advanced users)

3.Locate the ECU BDM pin 1 position

pin 1 is usually not clearly marked on the ECU BDM pin out
on an ECU with the standard Motorola BDM pin out pins 3 and 5 are connected to ground –

this can be checked either visually or using a multimeter tool refer to other sources (Internet) to get more information on the pin 1 position for your ECU

Place the desired adapter in the frame saddle

make sure the pogo pins are facing out
lift the saddle so that the ECU can be slided under the frame adapter saddle

    Place the ECU on the frame

inspect the adapter for pogo pin 1 location which is clearly marked
rotate the ECU on the frame so that the adapter pogo pin 1 and ECU BDM pin 1 match
make sure ECU is firmly sitting on the frame
double check the ECU position

    Connect the multiplexer board and adapter

at this point multiplexer board should be connected to the adapter via MUX connector
this will allow LEDs on the adapter to illuminate the area of interest (where the pogo pins need to touch the ECU BDM pads)

do not connect the tool yet

Connect the external power (+12 V) to the multiplexer

multiplexer external power is used to power the LEDs on the adapter allowing easier

positioning of the adapter pogo pins on the ECU BDM pads

red LED on multiplexer board will light up when external power (+12 V) is present
at this point the white LEDs on the adapter should also light up
do not connect the tool yet

    Fine tune the ECU position

lower the frame adapter saddle to almost touch the ECU BDM pads
each adapter pogo pin needs to sit on a separate ECU BDM pad
if pogo pins do not sit on the pads you may be using the wrong adapter – do not use the

adapter in this case!

    Lower the frame adapter saddle

each adapter pogo pin should sit on one ECU BDM pad
minimum down force should be applied when making the interconnection between the adapter and ECU

Double check the adapter pogo pin and ECU BDM pad interconnection

in order not to damage the ECU and/or tool make sure that the steps above have been

performed correctly

    Connect the tool to the multiplexer board

only connect one tool at any given moment to the multiplexer
make sure to use the correct 10-pin IDC connector (FGTECH, XPROG, BDM100&KTAG)

for interfacing the tool used:

○ use provided 10-pin to 10-pin cable with FGTECH or BDM100 tools

○ use provided 10-pin to 16-pin cable with XPROG tool

○ use manufacturer 10-pin to 25-pin cable with KTAG tool

do not connect the tool to the 10-pin IDC connector labeled MUX
do not power up the tool yet

    For Bosch adapter only

Bosch ECUs need to have ECU power supplied on the pogo pins (2 and 9)
some tools provide dedicated ECU power (BDM100, KTAG) while others do not (XPROG, FGTECH)

Bosch adapter can be used in both cases, providing that the jumper is properly placed on the 3-pin header (found on the adapter)

place the jumper on the adapter on the 3-pin header to the correct position:

○ place jumper over left and central pins when using XPROG and FGTECH tools – this will use +12 V power delivered from the multiplexer board (external power) for powering the Car ECU Programmer

○ place jumper over right and central pins when using BDM100 or KTAG tools – this will use

+12 V power delivered by the tool for powering the ECU

    For Siemens, Delphi and Marelli adapters only

Siemens, Delphi and Marelli do not provide ECU power on the pogo pins
in order to power the ECU +12 V and ground signals needs to be connected to the ECU separately (usually over the ECU interfacing connector)
in this case ECU power can be taken from multiplexer board connectors J2 (+12 V) and J3 (ground), otherwise provide the +12 V ECU power from additional source
refer to other sources (Internet) to get more information on the location of the +12 V and ground pin location for your ECU

    Connect the tool to the PC (or power up the tool)

perform software installation as described by the tool manufacturer if not done already
at this point the multiplexer, adapter and the ECU should be properly interconnected with BDM signals and power lines

○ multiplexer red LED should be lit up

○ adapter white LEDs should be lit up

○ ECU power (+12 V) should be present

connect the tool to the PC (usually done over USB or serial connection)

    Perform BDM operation(s)

start up the software package to operate the tool
perform desired BDM operation(s)Note: The user manual is used for reference; in fact, it depends. Try on your own risk.
