This two options in E-sys should be enabled only when I want to write VIN to module ?

What charger is good for flashing to avoid interruption during process ?

No, these have nothing to do with writing VIN to module. VIN is written to module during flash, either taken from FA or manually specified on the TAL screen.

Use any charger good for 50 amp minimum.

VIN is also taken from FA during vo or fdl-coding, usually no need to flash for matching vin.

But Update VCM and MSM I don't think have to be checked. This is for other purpose.

True, they are not needed when changing vin during a flash, I misunderstood your reply. Still they are required when coding a replaced module (after installing it), otherwise svt in vcm will not be corrected.

Yes, good point about SVT.

So I don't need to flash FEM to write my VIN ?
How to check VIN number in FEM?

How much time takes flashing module ? Is it time measured in seconds/minutes ?

 

[ap90500]

I have never replaced FEM but on other modules VIN changes according to FA when you just code the module. You can check the VIN by reading coding data from a module, it is shown in SVT-tree after reading.

how much time takes flashing module process ?

 

[shawnsheridan]

It depends on the module. I have no idea on FEM. My guess will be around 20 - 30 minutes.

 

[ap90500]

I would say that FEM takes maybe ten minutes, but I have not flashed it separately. NBT takes 25 minutes, and it has much more data (though it has ethernet, but so does FEM).

 

[shawnsheridan]

Iv'e seen CIC take 45 minutes, which is why I guessed 30 minutes for FEM given its size. Time depends too on how old the current firmware is relative to the new firmware, and how many firmware files actually need updating.

 

[__mkw]

during flashing car engine should be running ?

 

[ap90500]

No, it should not be running. You need power supply with 13-15 volts and 50 amps. Other option is to use another car with engine running and jump start cables.

 

[__mkw]

what if during flashing proces ignition will switch off ?
what damages to the car this may do?

 

[ap90500]

It won't turn off after the flashing has started.

I was trying update FEM, but ended with this error:
TAL execution started.
VCM Update: VCM-Update is deactivated. VCM will not be updated. [C197]
[Exception - UNKNOWN] FA must not be null when trying to execute a TAL containing coding transactions
Fatal error while executing tal!
Asynchrone programming failed! [C049]
FA must not be null when trying to execute a TAL containing coding transactions [1358]

In E-sys settings I have unchecked this "Update VCM after TAL execution".

 

[shawnsheridan]

At top of TAL Processing screen, did you hit the Read FA button before executing TAL?

 

[__mkw]

Yes. I hit "Read FA"
In the near field shows up filename: FA_aus_VCM.xml.

In the ECU list there are two ECU with text FEM (FEM_BODY, FEM_GW).
What the difference between them ?

That is normal. FEM_GW is the part that is Central Gateway module, and FEM_BODY is the rest of FEM (FRM, CAS and JBE).

VCM is located in FEM, so you must first go to VCM-module in esys expert mode, and copy VCM backup from backup to master.
