Hey there,
i have kind of the same issue with my CVX 1170
FMGR 252 / 253
ECCU2 none shown, like can't read it
AUX 1 / 2 / 3 / 4 - FC 011
also Fuse F50 25A blows out sometimes
By startup it shows FMGR, ECCU, AUX.... in the dash.
I checked power and ground of the ECCU2 seems okay, all wiring about 0.7 Ohm, no short to + / - at the moment.
PCB no viewable burnout, checked the connectors and pin's
ECCU2 looks good, had it open also no burns, marks or water
AUX 1 - 4 disconnected nothing changes
checked the 120 Ohm connector Plug next to the spools, also fine
Wiring to AUX 1-4 checked, from connector X6/83 to X4/90 ..... 93, all wiring 0,6 Ohm
CAN between FMGR and ECCU2 checked the wiring 0.7 Ohm CH / CL no short
CAN BUS 60 Ohm
It "feels" like a damaged wire at some point. It's not always present. Anyone another idea to this? What do i miss at this point.
Dealer told me could be a wire, not a big help....
I have another TVT 170 with no issues, i already changed the ECCU, armrest CAN-Modul and the FMGR, but nothing changes.

SOLUTION
I was able to solve my problem. The wiring harness under the cabin, on the right-hand side, was ground / broken at the transition to the center console. There was a massive problem here in the corrugated pipe, open, broken, sanded, oxidized cables, there was probably also a short circuit here from time to time, in total I replaced about 20 cables, some of them as a precaution.
You have to expose the wiring harness for this, only then can you see the problem, this is caused by the sand and dust that falls into the corrugated pipe and cannot be seen from the outside.
Very unfortunate place, you had to remove the floor of the cabin and the firewall from the engine in part, then you can work quite well. The fuse diagram is also not quite correct, in my case there was a small 5A fuse for terminal 30 of the ECCU, as well as a relay. Cables to the EEM were also affected, which I also checked and repaired in the process.
All in all it cost about 60€, I'd rather not count the time...
Maybe it will help someone else with a similar problem.
