CAScontrol-2 with EGS 6HP / DSG support

What’s new and major differences:


Highlights:


Connection:

Some common situations:




Some things to know:


  1. status_ews_egs_lesen - egs status monitoring;
  2. steuern_ews_egs - resets EGS to virgin state.



Overall:


Main software:

EWS2 functions:


Everything is as simple as possible -


In case of EWS2 ISN is always 12 bits long. That's why first digit is always replaced with 0.


When sending something to line be sure that EWS / CAS is disconnected (or at least inactive).



EWS3 - logger:



In case of EWS3 ISN is 16 bit (2 bytes) long, rolling codes are 32-bit values.

EWS3 - emulator:


  1. must set EWS / CAS or emulator for alignment, fixed ISN code is sent to ECU now,
  2. must send command to ECU to accept this value. Use INPA, DIS, Tool32 or any other suitable diagnostic tool.

Note that INPA script tries to communicate with CAS or EWS first. Ignore any errors and continue.


EWS EGS 6HP / DSG:

or:


Then you can use any diagnostic tool to check EGS status and unlock it (reset ISN) if necessary.

Connection to EGS 6HP (GS19D) –


It is a good idea to make some wiring harness:



CAScontrol2 line must be connected directly to PA_BUS. Diagnostic tool you can attach directly to PTCAN.


Terminate CAN bus with 120 ohm terminator.
