Code 233 directs you to code 430: Missmatch between the str-cmd inputs.
Go to analyzer menu A4.22. Record the voltsge for full left, full right, and neutral. Go to A4.23 record the record the RPM for the same positions. If the readings don't match then there is a most likely an issue with the wiring for that circuit. If they do match then your access 4 is bad.
With the fact that code 352 does not exist I'm leaning more toward a bad access module.

if you have multiple error codes your mast cables are probably faulty
