With me it is Chassis Control, which is supposed to be not present according to Durametric... that I could not read out yesterday, I wanted to check the wheel sensors.
I do have an early 957, which is a bitch to read out anyway.
Unfortunately my laptop was empty, so I couldn't investigate that deeper. I can imagine, however, that possibly in the first models control units of the 955 were installed. Therefore I will select another vehicle at Durametric.
