Hello everyone, I have a problem with a mercedes vito w639 EZS, the key is recognized, ELV works the key turns on EZS but the dashboard does not light up and the engine starts then stalls and the centralization does not work

With these symptoms you have more than you need to start diagnosing the vehicle, do it and we can move forward.

thank you for your answer, I don't have the car, I only have EZS, ELV, engine ecu and dash
I asked on the forum if there is someone who can give a connection diagram .... but no one shows up

If you have a chassis number for these components, send me a diagram of how you are connecting them.

This is mostly the key. Try your spare key !

EZS and KI you have to connect them through both CAN (C and B) and the UCE to CAN C, after connecting them you must check that the resistor without power on both buses is 60 Ohm, otherwise add a 120 Ohm resistor in parallel to achieve the nominal 60 Ohm.
In connector B of the EZS you have the two CAN, pins 5 and 6 (Low and High respectively) is the engine CAN-C and 7 and 8 (L and H) cabin CAN-B.
Regarding the IC, you have CAN-C (motor) on pins 1 and 2 (H and L) of connector 1 and CAN-B on pins 3 and 4 (H and L)

Hereby a schematic that explains the interconnection of EZS and ELV and schematics of the Instrument Cluster.

W634 can use ELV emulator and it is plug&play and it is cheap,
no programming and activation is needed.
this kind of emulator also for Sprinter Vito Volkswagen Crafter W169 W245 W202 W203 W208 W209 W210 W211 W639 W906...

Hello everyone, I come with news, I have all checked it was the corrupt dump, I injected another dump and redid a key, the centralization works, the engine starts, only the dash remains which does not light up
