I only have US version codes , but you may want to build this simple tool and see what you get at pins 3, 8, and 14.

E320 16 PIN DTC Charts inc. pin 8, pin 14

Will try that out on Pin 8 coming weekend, this model only has socket for pin 1, 6, 7, 8, 10 and 16.

I am not familiar with the Euro set-up.

The pin 1 and 16 would be ground [1] and 12v+ [16] to power the led, but I have no info on the others or codes for that model.
I would expect HFM to still be 8.........

Which pin did you get the code 10 from?

Yes pin 8 is HFM and I got code 10 from pin 8.

From what I could find out
Pin 6 - AirBag
Pin 7 - A/C
Pin 10 - Not used for my model

I see a TN signal for 10...but , US version.

i would still go into 8/HFM with a led tool and see what comes back as Flash code. Your scanner may be showing the Benz HHT tester format for the 77 b/c there is NO flash code 77, [ only up to 50]... but that could be b/c flash format for 77 is 31 blinks...which list as "Not Used" , but maybe it is used on Euro HFM ???????????????????????

{ Benz HHT numbers are digital and not the same as analog Flash format]

You are right, this software has both Analog and Digital Test, i ran the digital test on Pin 8 and got the code 77. I will try Analog and see, that should code equivalent to LED tool?

Thank you

31 blinks............
