KTAG KESS KTM BDM adapter Full Set http://www.chinacardiags.com/wholesale/ktag-kess-ktm-dimsport-bdm-probe-adapters-full-set.html is an electronic circuit intended for BDM operation on supported ECU. The adapter provides pogo pin based connectors for inte***cing the ECU BDM connector. Inte***cing 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.)

So, how to use DM adapters with Ktag Kess KTM100 Dimsport?

Steps outlined below describe a safe procedure when connecting and powering up the setup. Always be sure to provide the ECU power (from either tool or external source) after the adapter has been secured in a desired position - touching the ECU BDM pads. This will prevent you from short circuiting the setup.

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

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)

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 *** 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 inte***cing 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 adapteronly
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 ECU

○ 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 inte***cing 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: This is used for reference; in fact, it depends. Try on your own risk.
Reference:

Here is a list of words that are used throughout the manual with corresponding explanation in order to minimize misunderstandings when reading this users manual.

ADAPTER

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

IDC connector for inte***cing the multiplexer board.

BDM

is an acronym for Background Debug Mode, an inte***ce designed by the Motorola company, widely

used in automotive industry, present on modern ECUs. Not all ECUs are capable of inte***cing

through the BDM - see Appendix for the list of ECUs that support the BDM inte***ce.

ECU

is an acronym for Engine Control Unit, a piece of hardware containing electronic circuit used to

control and monitor the vehicle engine operation.

ECU BDM CONNECTOR

is a set of pads found on the ECU, used to interconnect adapter with the ECU in non destructive

way - usually by the means of the pogo pins. Most of the ECU BDM connectors have their pads laid

out according to the standard Motorola BDM pin out. Some ECUs may have proprietary BDM pin

outs or BDM pads scattered all over the ECU PCB.

FRAME

is a mechanical contraption used to fix the adapter for the BDM operation. It usually allows sliding

the adapter up and down to get it into contact with the ECU BDM connector.

MULTIPLEXER

is an electronic circuit board for inte***cing any adapter through the 10-pin IDC connector (MUX)

with one of the supported BDM tools through the designated 10-pin IDC connector (FGTECH,

XPROG, BDM100&KTAG).

TOOL

is a third party piece of equipment used for BDM operation – supported tools include

BDM100, FGTECH, KTAG and XPROG.
