My 2003 x350 was running fine except for the dreaded gearbox surge although ive already had the fluid and pan changed it still does it, Someone sugested to clear adaptions and reflash the tcm, it got half way through the precedure and then on screen said the reflash was a combined ecm and tcm reflash and did i want to continue so i did, then it said that it was unable to comunicate with the ecm, i aborted and restarted SDD and the vin which is normally found straight away was unable to be found so i put it in manually and managed to go throught the reflash precedure again but had the same result,
the car now wont turn over and has warning messages of
dsc unavailable
parking brake fault
air suspension fault
gearbox fault

The battery is only 3 months old, i am at a loss and unable to move the car,
the car was fine before i tried the reflash, hopefully someone can give me some advice
when sdd shows the modules the ecm has a red x on it which nit never had before

 

Experts will probably chime in and give better advice than myself.
Few questions though:
- did you hook a battery charger when doing the re-flash (a re-flash is consuming a lot of current and going below some voltage thresholds during the reflash may corrupt the process)?
- what kind of device did you use: a genuine VCM or MongoosePro, or a cloned device (cloned Mongooses and even genuine MongoosePro do not always communicate correctly with the modules)? In addition, abortion during the process may corrupt files.
Hope you can get good help here

 

i used a mongoose pro. i had 11.7 volts showing when i did it, i diddnt abort it, a window popped up saying that it could not comunicate with the ecm

 

11.7 V is far too low: the charger to be hooked on the battery when using SDD is there to maintain 13.4 V !
Also was it a genuine Mongoose Pro from Drew Tech or a clone? If a clone, all stakes are on...

 

Surprising SDD would even allow you to reflash any modules without the voltage being at 12.9V or greater. (Battery icon on SDD screen should be green)

You need to put a 30a or higher power supply/charger directly to the battery to keep that voltage literally above 13.0V

When I reflash modules I have a 100a supply with a digital dial that allows me to set desired voltage. I set it to 13.6V

A big +1 to SDD draining the battery during reflashing. Even battery chargers under 30a might not be able to keep up proper voltage during reflashing.

If the battery falls below 12.0V during reflashing it can essentially brick the module(s) being flashed.

Hopefully this is not the case with yours but that red X under ECM is not a good sign at all!

And if your not using a genuine Mongoose/SDD odds are even higher of bricking modules.

Also, keep your laptop powered when reflashing modules and turn off the sleep/stand by function on your screen when power is attached...

 

Is it a clone mongoose pro, or authentic drewtech adapter?
Any clone is almost certain to fail to program the ecm tcu.
I have had exact same problem. Three different adapters, even with full 30A and 13V on battery.
All issues went away once I used the proper adapter. Same with another member, I shared my adapter and he was able to reclaim his car too.
You will have to go thru a ecu reflash.
What version SDD? V125 worked better than later versions for me.

 

I am using a genuine mongoose pro with , I think sdd 131

 

/Where did you buy this "genuine" Mongoose Pro? How much did you pay for it? How is the SDD V131 installed on your laptop? Virtual machine?

+1 on the low voltage, an X350 draws 25A with the ignition on, drains a battery very quickly, you must have a big enough battery charger / power supply connected to keep the voltage up.

 

its in a laptop that has nothing else on except the sdd, ive been using it for 18 months with no problem

 

If you can't answer the questions you won't get any help!

 

The issue is not the laptop itself and you may have been using it without problem as far as you do only codes reading with a correctly installed copy of SDD v131 and a clone Mongoose, Pro or not Pro (the real stuff is sold by Drew Tech ca. 600 USD).
But flashing a module is another story. Plenty of stories, see for example here:

Hope your modules can be recovered by using a genuine system, good luck

 

Thanks il persevere but i fear the worst

 

Going to guess your using a clone. If that's the case your module is toast and may only be resurrected via genuine software/hardware.

Good Luck!

 

Whats the worst? Going to the dealer or paying $600 for an Original adapter?

I doubt the ECM is damaged and it should be able to be flashed with a proper adapter. Have used more than 3 clones and could do most things, except program the ECM VID.
