How toaccess MS CAN bus using FORScanV2 andmodifiedELM327
I bought this a few days ago and modified it so I could use the MS-CAN connection.

Images with the modification I made to use the MS-CAN connection, following the
instructions as follows.
Many Ford and Mazda models (approximately since 2003-2004) are equipped with MS CAN bus,
in addition to the regular HS CAN bus. In contrast to HS CAN bus, MS CAN bus is not supported by
the stock ELM327, because MS CAN is a manufacturer-specific solution and located on non-OBD2
pins. However, ELM327 is very flexible tool, and small modification allows to implement the MS
CAN support.
Note for Mondeo Mk3 owners: only models after restyling in July 2003 have MS-CAN modules.
And this bus only keeps few modules like ACM and EATC. You do NOT need the MS-CAN
modification to access engine, ICU and all other modules except ACM and EATC.
This article contains of 2 parts: modify ELM327 to add the HS/MS CAN switch, and some notes
about MS CAN support in FORScan v2.
Note: If FORScan doesn't ask you about HS/MS CAN switch (see chapter 2 below), it means it
doesn't suspect MS CAN modules on the board and will not check for them, even if you modify
the ELM.
1. Modify ELM327 to add the HS/MS CAN switch
ELM327 supports HS CAN from the stock, because Ford HS CAN completely matches to the OBD2
standards. It occupies pins 6 and 14. MS CAN bus occupies pins 3 and 11. The picture below
illustrates the thing (ATTENION: the OBD2 jack on the picture means vehicle one, "female". The
adapter's one is "male", so it is "mirrored". Pins are often mixed up because of this. Always note
pins' numbering of the adapter's jack!):

2. The simplest way to implement the MS CAN support is to add a switch that will shift between
MS/HS CAN. The scheme below explains the modification (ATTENION: the OBD2 jack on the
picture means vehicle one, "female". The adapter's one is "male", so it is "mirrored". Pins are
often mixed up because of this. Always note pins' numbering of the adapter's jack!):
Roadmap:
Purchase a 6 pin mini-switch of ON-ON type (for example, MTS-202-A2) in any shop that sells
electronic components, also prepare a wire

3. Disassemble ELM327 (for majority of china clones - carefully remove the label that hides 4 screws,
unscrew them)
Find a place for the mini-switch (most complex part of the whole operation for some devices that
are extremely compact)
Unsolder wires from pins 6 and 14 of the OBD2 jack and solder them to the 2 middle pins of the
mini-switch
Solder 2 new wires from 2 outer mini-switch pins to pins 6 and 14 of the OBD2 jack
Solder 2 other new wires from 2 other outer mini-switch pins to pins 3 and 11 of the OBD2 jack
Check the work (it is very important to do not mix CAN-L and CAN-H wires up!) and assembly the
ELM327, mark the MS and HS can position on the device box to avoid confusion

2. FORScan v2 MSCAN support

4. FORScan v2 has support of MS CAN bus and optimized for using the HS/MS CAN switch. There is
no necessity to adjust any ELM327 parameters for MS CAN, FORScan makes all the necessary
changes in an automated mode. When FORScan establishes a vehicle connection, it analyses the
vehicle configuration. If MS CAN modules are expected, FORScan will ask user about HS/MS CAN
switch:
If no question is asked, it means FORScan doesn't expect a presence of MS CAN and is not going
to look for it. If user confirms the MS/HS switch presence, FORScan will ask user to shift the bus,
for example:

5. FORScan v2 is optimized for using the HS/MS CAN switch (minimize number of necessary shifts).
For example, reading DTCs in all of 5 HS CAN modules and 2 MS CAN modules will always require
only 1 shift.
