HKA codes A/C

[X5chemist]

It's hot! The A/C stopped working while on errands on Thursday.
I left early in the morning and it was ice cold. Halfway through my errands, it would not turn on. Luckily, it was not too hot yet. Yesterday, I checked for codes. Even used the Foxwell 520 Pro to activate the compressor. No go. I checked all the fuses. Even the big 50 amp one.

Does the circuit go through the pressure switch? I need to pull out the Bentley manual to check wiring diagrams. The compressor spins freely. It's not locked up. The previous owner listed A/C work. The compressor does look replaced. Its clean compared to the block. It had an oil pan leak on that corner until a gasket replacement stopped it. I've wanted to swap out the pressure sensor since a new aux fan was installed. It sucks that the entire system has to be evacuated. I'll try to reach the compressor connector to ohm it.

Codes:
1B HKA: Magnetic coupling A/C compressor
15 HKA: Pressure switch
