Multiplexer Error Code

Hi, I have a EP3 with a built K24 engine with a Comptech supercharger.
I have this annoying problem with my Kpro intermittently throwing a 39-1 P0600 Multiplexer not present problem.
Can anyone please point me in the right direction as to what I can do to rectify the problem? I have to disable the
Multiplexer and with that, no aircon!
I have checked grounding, replaced the Multiplexer and still throws the same occasional Multiplexer error code.

HAve you followed the factory service manual (Helms) troubleshooting for this error?

Ok will consult the service manual, but no other suggestions on what the issue might be?
