my comand screen stopped working recently i got the car hooked up to a scanner
its a 2016 MB CLS 220 D
ALL OTHER FUNCTIONS ARE WORKING---RADIO,BLUETOOTH,CD,SOUND.............. it's just the screen is not functioning
this is what shows up

can anyone give me info on this or might have had the problem previously

thank you in advance

bobby.

 

I haven't it looks like the can bus is being interrupted with some sort of piece not communicating or a broken wire or connector. I would look at the MOST fiber optic loop as well, I'm not 100% it would throw this code, but often of one piece fails on a MOST loop the entire loop drops. There are MOST loop defeaters if necessary. Often on L322 range rovers a piece would get "wet" in the trunk, like bluetooth, or CD changer, for example, the fiber optic loop would be interrupted and the screen would not work. Using a MOST defeater is incredibly easy now, they sell them on the bay for like $10, which is much easier than making your own (which you had to do before the defeaters were available).

 

where would i start looking for this ?

 

On jlr, and fairly sure here too. Take each fiber optic out one at a time. There should be one piece where it is receiving but not transmitting. Or one piece with no lights the piece earlier in the loop is out.

 

thank you for this information
but being a bit of a dinosaur where will I start looking for these fiber optic cables

thank you

 

Display is on but malfunctioning - MBUSA wiring but should be same since COMAND (a40/3) unit is working properly start by checking f11 (7.5A) @ front SAM (n10/1) if fine pull for 10 minutes or so in an attempt to reset display. No difference, check connection to display (a40/8) fine, disconnect & reconnect in an attempt to reset.

 

thank you sir
