Air Body Control U042386

[moufassa]

I have a problem with AIR BODY CONTROL. After several full car trouble code readings and clearing them with Xentry, I still have the error code U042386: "Implausible data was received by the instrument cluster. There is an incorrect signal."
I reset the SPC213 and SPCH213 ECUs and also the IC222 (instrument cluster) but the result remained the same.
Software update or physical defect?
Note: AIR BODY works great.

The first thing I would look for is a software mismatch between the ECUs. It is possible that the SPC213 or SPCH213 (Air Body Control ECU) or IC222 (instrument cluster) are using different software versions, causing them to send or receive data that is inconsistent or "implausible". The second possibility is loose, damaged or corroded wiring, which can cause intermittent signals, resulting in an "implausible data" error.

Thanks for the reply handygraphy. Regarding software versions, I have not performed any software updates or reflashes. Instead, I will check the integrity of the wiring.

I visually checked the connectors but didn't find anything unusual, possibly software incompatibility.
I have a question. To update the instrument cluster, which software from the list should be updated or should I update everything?

You requested a backup copy of some ECUs in my topic.

Ok. I am sharing my PTCM222. But could you please share your IC222 and SPC213-SPCH213? I'm...

As I said, I don't have AIR BODY CONTROL, so I'll share my backup copy of the IC213 analog cluster saved with DTS Monaco 8.
