2005 Mustang No Start

[Blacker]

In the middle of the reflash, the write failed and now the car will not start. I have tuned the car on the dyno and had no issues. Any ideas?

I would guess the cars battery went to low to finish the flash. Check the battery volts and if they are low place a charger on the battery and try Re-flashing.

[Blacker]

I will check that and hopefully do not need a new PCM.

[Blacker]

I connected the battery charger and the battery was good. It was at 85% and still cannot flash the PCM. The scanner will not connect either. Is there any way to reset the comm bus? The dash shows DTE ODO Data Error.

[Blacker]

Checked PCM fuses and diodes as well. Nothing stands out and still troublshooting. I also made sure the OBDII port had power.

try an older one that worked and see if it will recover the flash. if not email support as they have a newer one out now that may fix it.

[Blacker]

Still will not find the VCM. Also, the dash beeps a lot more and has faults for the Traction Control, ODO, Fuel Level, etc.

seems similar to my 2009 issue I had a few days ago. In my case no power failure, not even writing, but PATS got activated. Bill send me a beta version and it could recover PCM. The latest and greastest could not either.

contact support

I would email support.

I email them and being Saturday, not expecting any timely feedback. I am having it towed to a Ford Dealership and I will go from there.

I just had the same problem tonight tuning a 2005 any ideas on how to fix this problem?

I had the same problem... used an older beta version and it worked great, got the vcm recovery up and working with no problems

[Blacker]

That is good to hear and the Mustang is at the dealership. I called the service advisor and left him a message that I want another shot at recovering it. They haven't started working on it yet and do not want another PCM. Those things are $750 and they still need to flash it for more $$$.

[Blacker]

Well, I used an older version and it worked. The VCM recovery worked as normal and the Mustang started right up. Thanks guys and if I could by a round of beers, I would.

[Bill@HPTuners]

Newest beta also should be able to recover as well.
