I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Thank you,

The control unit is located at the back of the van on the passenger side either below the light unit or behind the right rear paneling. If the unit detects incorrect resistance of the valve unit or compressor- it will not actuate anything besides the warning light in the cluster.
I suggest to check the resistance of the valve unit and compressor.
Also, the system will activate only after deleting the fault codes in the control unit.
