Have collected common ways to read and write BMW CAS 4 data, including new (
Yanhua ACDP) and old methods:
Method 1: cut down cables
Method 2: remove components
Method 3: lift pins
Method 4: done by ICP
In detail....
Method 1: cut down cables You should disable 2 connections in the PCB; that is, 2 cables need to be cut
Then need finish connection as before, after data is read and written
It’s risky and may lead to damage to the module
