How many ways to read/write CAS4 data? ACDP the best?

Have collected common ways to read and write BMW CAS 4 data, including new 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

Method 2: remove components

You need remove 4 components in the board

And then desolder all after data is read and written

It’s time-consuming and requires desoldering experience

Method 3: lift pins

You should lift chips and put them back after all is done

Some data might be lost because of bad desoldering

It’s risky, difficult and time-consuming, easy to damage pins on the chip

Method 4: done by ICP

 

ACDP is the best, compared with all methods before.

Easy:

Board with ports is used instead of desoldering

No need cut down cables, lift pins, remove components and desolder anything
