Help, i just ****ed up

[Benltr]

Well...

i went to put stock tcm tune back-on and i accidently clicked on the full flash ecm tune instead...

I didnt had time for the full reflash because i had an exam and i disconnected the autocal... (i know this is stupid)

The truck just popped dash message : service trailer brake, service 4x4 and another one...
The light are staying on too and even if i remove the key the electrical stay on (dash)

I cant lock the door with the button on the key...

I tried to full flash again and nothing change...

My truck is sitting in the driveway with rear light open and front "flasher" too.
It wont crank at all... nada

Anyone have idea ? I was going to disconnect battery...

This could very well be bad. If you cut off a full flash, you might have bricked your ECU.

If you connect EFILive, and hit "Check Status" on the flash window, what does it say?
Are you using EFILive v7 or v8?

Hes using a autocal he said not sure if they work the same??

 

[DAVe3283]

Oh, right. I can't read, apparently. Hmm, any error messages on the screen when you try to flash now?

 

[Benltr]

i tried another full flash and it completed 100% without error.

I do have 3 DTC too...

I unplugged the battery all night. I will try this morning to replug them and full flash again and see how it goes...

You might try full flashing with a TechII.

Otherwise, perhaps try the Emergency Relearn? do a search, I think it's a sticky note at the top of the tuning forum.

 

[duratothemax]

emergency relearn is only for VATS Pat...not going to do anything when theres no OS/calibration in the ECM.....

the only thing I can suggest is disconnect the batteries for a while, then reconnect them and try to full-flash the ECM again. If it wont let you full-flash the ECM than its good night alice for your ECM...

If he could "talk" to the ECM, but it doesn't start, perhaps it screwed up the VATS code?

A bricked ECM won't take a flash at all, or even start the flash AFAIK.

Joe at PPE "fixed" a bricked LBZ ECM for me. Not sure how he did it, but a TechII or EFI could not do it. I would give my right leg for that tool he has, but he's not letting it out of his sight.

That kind of dismisses the whole "PPE is a stereo store that copies other people's stuff" argument. Joe made that tool. Nobody else has figured out how, not even General Motors.

Solved!!

After a night without battery, i repluged them and tried to start but it didnt had ennough juice.

I charged them and boom the truck started. I let it idle for a while and i went for a ride... The same truck as before

He's alright now..

The only thing is i still cant figure to put stock tcm tune back on... I was able to put the modded tcm tune but i remember Rob had some problem with my stock tune to be able to modify it... Can i use a stock tcm lmm tune from another truck? It seems mine doesn't work.
