XPROG-M is the cheapest & best tool for read and write. For 100%

 

Here you go.

Part 2: Xprog r/w EWS3

 

In detail…

 

Part 1: Xprog reads and writes EWS 4.4: success!

 

EWS 4 can be done with no problems.

 

Test:

BMW X3 E83 2006 with immo EWS 4.4, assembled on a Motorola MC9S12D64 microcontroller , with a 2L86D mask .

Important note:

Before reading EWS4 (4.3 & 4.4) you must check label on relay , if you see Made in JAPAN you don’t have problem for reading(R260 clone – R270Xprog HQ clone or original) but if you see Made in China you %50 have problem , if you try for reading eeprom %50 possible lost eeprom or mcu

if relay Made in china only via xprog HQ clone or original with +12v power external and lift extal pin.

 

 

Part 2: Xprog-m reads and writes EWS3: success!

 

EWS3 can read/write in circuit with xprog.
but you need lift pin TXD

 

Wiring:

On EWS:
Pin 9 is GND,
Pin 10 is 12V,
Pin 13 is K-Line

 

Test:

-EWS3 with 0D46J type HW03 SW08 can be read and written by K-Line.
-EWS3 with 0D46J, 2D47J type HW02/HW03 with SW01, SW02, SW03, SW04, SW05 could not be read and written by K-Line. Should be removed from the board and read in adopter.
2D47J If you read in adopter and read as 2D47j Secure.

Important note:

Desolder it ,and read with a ETL programming tool– is the best and safer way
through k-line is lottery

 

To be sure lift both pins,but why not than read on board

because usually has like a red glue all over the board that its not very easy to burn with hot air. This glue is also under the mcu…
