Using ista for a year or so now resolving different issues, i have noticed that my car throws different codes for “no communication possible” with different modules. Next time I scan (after clearing) there may be different modules. I’m talking about codes like:

S 0105
S 0119
S 0159
S 0180

Some of these are mundane but other times I see these codes for DME/DSC/other critical electronics.

My current issue is the ABS/DSC/4x4! which I think is a wheel speed sensor in my case, but I have heard about battery issues causing inexplicable symptoms and wonder if that could be what I’m seeing. Generally no symptoms associated with these codes, all modules normally fully functional .

Anyone experienced the same?

Are any modules on the Control Unit Tree RED? AFAIK, there is NO source for looking up "S" codes. Can you provide ScreenPrints of:
1) Control Unit Tree?
2) Fault Memory List, showing definitions of your "S" Codes, as well as any Hex-codes?
3) Diagnosis Scan Tab of any DSC/DXC Fault that causes ABS/DSC/4x4 warning light on Instrument Cluster?

See attached pdf: "Fault Memory & Test Plan", for specific steps to view/ Save/ Post those screenprints.

Hopefully these images work.

Below are all my codes AFTER replacing the front right wheel speed sensor, clearing codes, and test driving. The old one was lightly scuffed but probably functioning fine.

Not sure about next steps. Checked all my fuses today and found no issues there.

For reference:
55C3
55C6
5DEC
5E4C
5E4E
A8E8

Unfortunately didnt grab a shot of the control unit tree but I’ll add that tomorrow.

See pdf attached to post #2 for HOW to Save & Attach ScreenPrints of your ISTA Screens, so we can ACTUALLY READ THEM.

Ok, thanks George, back with fresh screenshots. The laptop i use for ISTA is not network connected so took some planning.

Consistent codes that come back after clearing are 55C3 and 55C6.
