I picked up two used ms42 dme’s to mess with, an obd pigtail from an e46 323i, and the dme electrical connectors from the same vehicle and a 350 watt pc power supply. I the dme up per pazi88’s instructions on his youtube channel and couldnt connect with mss5x flasher, and inpa said module not found and the Battery and Ignition lights were not lit.

I then, with the help of Enabled, hooked it up as follows -
X6001 Pin7 to +12vdc
X6001 Pin4 to Ground
X6001 Pin3 to OBD2-pin7
X6004 Pin32 to OBD2-pin7
X6004 Pin26 to +12vdc
OBD2-pin16 to +12vdc
OBD2-pins4&5 to Ground

Inpa Ignition and Battery lights up now but gives error “Data transmission Interrupted”, and mss5x flasher still says the same as before “no connection or unsupported ecu”

I have confirmed that voltage coming from the power supply remains at +12.27vdc when the dme, obd2 cable, and my tablet are all hooked up.

I am at a loss here, and if anyone has any input I would really appreciate it.

I've never had an issue with using just the x6001.
Also, some OBD2 cables don't have pins 7&8 internally bridged. You may need to do that.

Shoot i forgot to mention that my cables have 7&8 bridged.

If i hook it up off of just x6001, inpa and mss5x say no connection/no module found etc.

If i hook it up using x6001 and pins32&26 on x6004 inpa says data transmission interrupted, mss5x says no connection etc.

I am really quite irritated. I have the case off the dme and have checked to make sure power is atleast making it passed the x6001 & x6004 connectors. I looked for any traces of burnt circuit board, and it all appears good. Thats as far as my electrical circuit board testing knowledge goes.

Connect x6001 like this and it will work:

Thank you Pazi, I will give that a go next time I get a chance to mess with the stuff again.

And make sure to connect bootpin first, than put ignition on, and wait 6 seconds, remove bootpin and hit connect. Otherwise you Will get a connection error if you do it the other way around

Isnt important to put 6 sec there... also depends on speed of bus ...
Also only need for bootpin via e.g. JmGarage ... you can read and write with e.g. MSX Flashertool

Thanks a bunch, again, Pazi. Worked like a charm!
