Hello, I've recently installed a tow bar to a T6.1 4 motion - we've installed a few of the same kits but this is the first on a 4 motion.

The kits we buy come with comprehensive coding instructions, they've always worked first time with no issues, but this one has left an error in the ABS module saying "0602 - Function Restriction due to Faults in Other Modules" - we didnt take a scan before carrying out the work unfortunately.

I've gone back to the steps and checked that each change is still saved in each module, all the ones we changed are. There is a step called "Trailer hitch control module -> installed" under Encoding 09 Cen Elec Module which we haven't found previously or on this one either - that was my first thought as a potential issue.

Just looking at the installed modules, There is a step in the instructions if applicable to change in 74 Chassis Control - we have 22 AWD, I wonder if there is a setting in there that isn't listed in our instructions.

There is also a telematics fault which can be seen in the auto scan below, we see this fault quite regularly but never actually found out what it means?

Could someone point me in the right direction to start looking please?

@C_V: Hi.

hmm....... for your hex09 question - does your BCM have an adaptation channel similar to:
  • ENG122979-ENG141968-Networking-Anhaengeranschlussgeraet (meaning=Networking - Trailer connection device)
If so, try setting the value to "installed"

T6.1 has a similar one: "ENG122979-MAS01374-Networking-Trailer"

Hmmm... no such thing in T6.1 hex03 adaptations... although I had catched the below in a T6.1 with OEM trailer electronics (factory installed).

Is that "[Dst_EpsTorqReqRejected]" not referring to the power steering, take a look at the coding or adaptation in hex44.
