MS2 wont flash
 

So i got my new MS2 built and i used my old MS2 daughter board. I went over the whole build before i even powered it up. Everything looked good, so i powered it up and everything seamed good. The lights flash once when i turn the key on. So i take it everything is good, so i try and flash the ms2 but no matter witch way i try to flash it i cant get the MS2 to communicate.

Any one know why my ms2 is not communicating?

Boot jumper in?

yes boot jumper in.

The three led only flash when i turn the key from off to run. They only flash once very quickly.

Could my daughter board be bad?

You need to do the serial loopback test that are called out in the build manual to try to rule in/out what could be wrong, but with the way I understand that you had grounded your MS2 through the EDIS module, I wouldn't be surprised if the processor is fried.

I tried that test before i posted so im guessing my daughter board is no good.

Here is a screen shot of what i get every time i try to flash MS2.

Okay i got a new daughter board and check everything over and over more time then you could shack a stick at, and still no flash. WTF What could be wrong matt went over my wiring and i fixed a few small things, the ecu looks fine no burning or any of that but still cant get it to flash. I tried 2 laptops and 1 desktop still nothing.

lars would get that same reaction on a mac. used my pc and it flashed instantly.

Braineack, Anyway i could send you my MS2 and have you flash it for me so this way i know it works???

What data cable are you using what os?

prolific usb to serial with a serial from diy and XP.

Okay anyone know what could be wrong??? I went over the board with a multimeter and everything reads good power, grounds, resistors, diodes, and capacitors. Could i have a faulty bored? I have tried other laptops and desktops just using the serial cable.


Matt anyway i could mail you my MS2 and have you guys look at it? Its the last part i need for my car i have everything done besides this MS.

Okay if i power up the MS2 and i check for power i have no power at the daughter board on the square pin.

That's pin 1 (Vsyn). Should be easy to trace back:

The link you have posted wont doesn't load.

Now the image works.

Just went over the board again and found i dont get any readings from r23 no voltage or resistances.

Also seams to only have 0.19volts on the daughter board.

Could this resistor be the problem?

R23 is in the clock circuit which the MS-II doesn't use, as it has it's own crystal on the underside of the board.

Were should i be looking???????????
