[didi_du_93000]

Hello all,


problem: In same time both 2 keys from car stop work. can't open/lock car AND start car.

Both keys are ok (read VVDI MB BGA).

So i have write new key in position 8.

When i put in EIS red light on key blinking to active the key.

After blinking the key is actived in EIS (read by VVDI MB BGA, see picture).

But can't turn ignition, and central locking not working too.

ESL is also not unlocked. I have put emulator and same problem.

EIS part number: 203 545 06 08


Do you think EIS problem or file problem?

Eis on table don't work.

So problem from eis.
Key number 8 not use.
I write a key on number 8.
Put in eis on bench.
Key actived after some second.
But can't turn the key.

My problem is how can I virgin and learn a eis if the data is corrupted?

Upload eis dump, maybe hash fault.

This old EZS have old mcu’s 2J74Y or 1J35D
try warm up with hot air and then read with mb tool, if can’t - read with programmer.

4J74Y have this fault change them with 1j35D.

[didi_du_93000]

Inside its 1j35d.

Problem solved. EIS hardware problem.
Have swaped memory from ori to donor using vvdi prog and all work great.

Thanks for all help.
