Attach questions and answers with more details that might help you.

 

You make it on the bench or obd?

bench

 

What’s better, leads on bench or vvdi prog and ezs adaptor set ?
What is better coverage and faster for all key lost

better on bench read pass 18 minutes only with fast adapter safe and secure

 

I see you use vvdi mb and leads to connect on bench
There is also vvdi prog with the ezs adaptor 10pc kit. No soldering involved too.
So was wondering which way is quicker or more efficient 

some of vvdi prog ezs adapters not same pin outs also why would i open eis while I can make it with one. Cable and read pass unless I dont wanna lose a token !!!

 

Does it use just 1 token on bench with cable in total ?
You will need 2 tokens on AKL on bench , Adapter 0 tokens

 

Ezs is easy to open once removed to put into the adaptors ?
I think I will buy that 10pcs vvdi prog adaptor set. Save expensive token price

Correct

(Schema) VVDI-Prog read 4J74Y on W639

This is schema for reading 4J74Y on EIS W639 Mercedes with VVDI Prog.

 

use wiring as 1L02M + OSC to 59pin = right and enough….but for read choice from MCU –> MC68HC(9)08 –> HC908AZ60 EEP (4J74Y) and success….i read through this way more 4J74Y in W639 EZS  all successfully read

wiring diagram for this MCU in W639 EZS coming soon in some next VVDI Prog SW update i think…

 

i make some pictures of this type W639 EZS with this MCU and with other one as 3K85K too
