Hello, after replacing the battery (car was few times started with jump starter) I have several problems:
black CIC screen, CIC controller not working, buttons on steering wheel not working, pdc no sound (green light shows on button), no warning sounds of belt or open doors.
The radio plays, I can adjust volume or change station by buttons on head unit. After turn off the car and taking out the key the radio still plays, I have to turn it off manually by pressing volume.
What could be the problems? CIC head unit has fried?

Questions:
1) What are Last-7 Characters of your VIN?
2) Are there any other faults read ("S-codes", etc.)?
3) If you are using ISTA, please attach a ScreenPrint of the Control Unit Tree (or Control Unit List). That will show what
Modules are NOT communicating with the OBD II Socket. You appear to have a bus issue.
4) Where did you attach Jumper Cables? To Jumpstart Terminals under hood? To Battery Terminals?
5) Do you have Auto Engine Start-Stop?

If CID is dark/ NOT functioning, then likely EITHER:
1) NO Power Supply (via Fuse F76), or
2) NO communication via K-CAN bus (Orange/Green & Green wires).

ISTA ScreenPrints of F76 circuit/Location, & CID circuit/X13822 Connector View, are attached.

Thank You very much for Your time

1) What are Last-7 Characters of your VIN?

VJ96048. My BMW has retrofitted CIC high (was small screen, now big) and mulf2high.

2) Are there any other faults read ("S-codes", etc.)?

Each time I clear faults and read them again, I am getting different amount of faults. Same is with control unit tree. A few minutes ago I red the faults, made ScreensPrints, cleared the faults and once again red the faults and made ScreensPrints. I will post it in the end.

3) If you are using ISTA, please attach a ScreenPrint of the Control Unit Tree (or Control Unit List). That will show what
Modules are NOT communicating with the OBD II Socket. You appear to have a bus issue.

Same as faults, I will attach two freshly made ScreenPrints. One before clearing faults and one after.

4) Where did you attach Jumper Cables? To Jumpstart Terminals under hood? To Battery Terminals?

Under the hood.

5) Do you have Auto Engine Start-Stop?

Yes, there is button "A with ring arrow" near the pdc button. But its ussualy turned off.

So here are the ScreenPrints made before deleting fault memory few moments ago:










And here are the ScreenPrints made just after deleting fault memory

When you changed the battery, did they knock the wiring just above it? There is a CAN bus junction point for the PDC module right there. Look for twisted green and orange/green wires.

Most likely one of your modules is bad and taking down the CAN bus network. You can disconnect modules or remove their fuses one by one to identify the offending module. Start with the ones in red in your pics above.

You might have 2 different problems here. Seems very strange you have different modules not responding at different times.

The most common cause of this is the COM port settings being changed by a windows update. Go to your COM port settings and check that the latency timer is set to 1.

This will not fix your CIC problem but will hopefully fix the issues with ISTA communicating with the other control units.

Thanks everyone for your advices.

My bad was not setting the latency timer to 1.

So now I have only 5 faults related to my problem.

In addition to suggestions & ISTA ScreenPrints attached to Post #2, I would suggest:

1) Check fuse F76;
2) Check Ground (Brown wire) at X13822/3 (CID);
3) Check Connections at:
a) X14272/1 (Red/Yellow wire supplying voltage);
b) X14272/27 (Brown Chassis Ground);
c) X14272/11 (Orange/Green K-CAN bus High;
d) X14272/30 (Green K-CAN bus Low).

As previously stated, LACK of modules to appear in "Tree" is usually related to NO Voltage Supply or ground, OR lack of
Bus Connection between Module & JBE (Hub).

Remove the floor of the trunk and disconnect the ULF and TCU one at a time to see if the CIC behavior changes. This may give you more clues. The CIC is the gateway to all the red modules you have above so there may be an issue with the CIC. The 0375 code is causing the other codes as the MOST gateway is in the headhunt.

The CIC is damaged
it should be available for diag with or without TCU/MULF connected via MOST

anyone find a solution, currently going through this, my cic sounds like it wants to boot up but no response radio works tho
