Hi,

I am trying to talk SSM to an 06 STI sitting on my bench (tested working and answering SSM request in my car). Here's my setup:

- 06 STI ECU
- VagCom cable

ECU wiring:

+12 V

-Control unit power supply B135 - 6
-Control Unit Power Supply B135 - 5
-Ignition Switch B137 - 14

Ground

- GND (controls systems) B137 - 1

VagCom wiring:

+12V Pin 16
Ground pin5 (pin4 & 5 are connected)

VagCom Pinout

Finally, I am using ecu pin SSM/GST communication line B137 - 20 connected to the VagCom cable pin 7 ISO9141-2 K-Line.

That is a working setup.

thanx

B136.16 is subaccelerator sensor power according to your diagram.
B137.20 is probably k-line but signal levels are not seemed correct.

Somehow I was using the wrong diagram. Now works perfectly.
