VITO W639 CHECK DUMP PLEASE

**GolfmkI** · 16th May, 2016, 05:45 PM

Hello!!!

I am checking this Ezs rigth now.

Keys are ok itself.
Coils ( Ezs and Key ones are ok also)

Both keys are good way, almost new...

But they stopped working suddenly ....

Ive resolder and no luck.
I need to check my flash dump to check CORRUPTION

IVE upload also Eeprom, perhaps Keys are hashed ( I dont think so)

If finally my data are OK, they are all readen with R270 Blue Rosfar.
Take it as there are no one with this Ref in Forum in Rosfar format.
Perhaps could help someone in the future.

Flash will not corrupt by itself (or maybe a bad battery). Eeprom looks good (no error, 2 keys active).
Did you check ESL? Common problems on Vito/Sprinter.

you can try emulate esl and see if ezs working

Of course I am emulating Esl

Because I am working in Bench

In fact the first thing ive checked is Esl, very common on Vito and Sprinter.

As I said I test tipycal coil key failure and also check coil inside Ezs.

IN fact last month Ive repair one of them with 1 coil circuit Open.

But now I dont KNow what is happening.

At least at this moment I can Know (thanks to you) that keys are not disabled and eeprom seems correct.

I am checking again whole Ezs.

I need to find where is the problem.

Any help will be appreciated, thanks beforehand.

I had a similar problem on a w639 but with 2x908. It was a fault on the pcb itself and i never found it.. swapped mcus to another eis and all was fine.

Problem was no 15R and no start, key opened esl and everything else was fine.

So try to find same eis and clone eeprom
