Change VIN number in EPS module Chevrolet Corvette C7 my14

[Adam Krasuski]

Hi. I need change vin number in EPS module in Chevrolet Corvette C7 my14. I bought DPS file from Troy to change Vin. When I try to used this file I have error Occurred During Programing. When I want  check Read Info from all modules I heve error Occurred During  Request Info , I checked on other car ,and  i can read info in all modules. When I make diagnostic by  GDS2  i have  connetion with all modules. Do you have  any ideas,  why DPS can not check Read Info.  I'm attaching it log files. THX

ProgramLog get controller info 31 eps.Txt ProgramLog eps VIN chenge.Txt

I might be wrong, but this line says 

 

">> !!! Not all expected ECUs responded positively!"

 

Is there any modules that can't commuicate?

I think file is made for Opel/Vauxhall. Never tested as I use differernt tool to change VIN in EPS.

With almost all modules are communicate, except one. Inside mirror module is not communicate, but i think it is not on the HSCan ,so he can not disturb in  communicate.  

I bought this file : https://www.cameraloops.com/files/file/322-eps-vin-change-corvette-2017-5-byte/  so ,  I think is made for Corvette. But why , I can not Read Info from any module? Additionally I used IO Terminal for cheked , and with IO is ok, I can read info about EPS.

The file you’ve downloaded is for 5 Bytes. Since yours is 2014, it’s likely that you’d need 2 bytes

Are you trying to do this with the engine on?  If you are, it'll always fail.  Key on, engine off.  That's normally when I see that error.  For the programming (DPS) part.  The reading will be something different.

He is correct, 2014 Corvette is for sure 2byte security, file you bought is not gonna work for you.

 Guys, look on the picture, this is read info from IP Terminal from EPS module, end the seed is 5 byte, another thing is that this EPS is not from 2014 but from 2019 , that why i bough  this file. Today I checked that i Can make Read Info from Low Speed CAN , but I can not  read info from High Speed CAN ( only by DPS in this car  , GDS2 works with all speeds).

Yes I checked with engine  off.

I think is because DPS receive wrong answer from EPS as been used in newer platform Vehicle.

I don't know when you did this log but you didn't get far enough yet to be anything else.  You wouldn't have been able to program any module on that bus.  I don't know if you didn't cycle the key between tries but you had one computer still unhappy.  I would cycle the key, try it again and see if it gets further than that.  I'm convinced like Lyobmir said, it's probably a mismatch but this log is telling me you didn't even get far enough for SPS to even ask what the current calibrations are.  In fact, you didn't even get far enough for it to even think about programming it.  Basically, I'm just saying that log file doesn't provide enough.  Can you turn the key off, reset everything, try it again and see if you get more detail?  It's like you've tried it twice and it left it in an errored state through that session.  Does that make sense?

I

 

 

I've looked at the log in more detail, I can tell the engine was off otherwise I'd expect the BCM and others to fail too.  If this is what's continually reporting conditions not met, you need to either find out why this module is reporting that, unplug it and try without (if you can) or try it on a bench.

Ugh, and I put the wrong module.  642/242 is actually your EPS.  You put it into a state that made it report conditions not met in the log you gave us.  I'm guessing that wasn't your first attempt.  Power cycle it, then try to program it and upload that log.  Again though, I'm thinking Lyubomir but the log you posted is misleading us.

Due different year think issue is with EPS pinouts and woke up signal. We tested. Someone with access to EPC for Global? Mine is only Opel and cannot search for part numbers. And no have money to pay for Cameraloops access
