System Description
WARNING: This page is about a different variant/trim than selected.
The ECM sends the engine speed signal to the air conditioning amplifier via CAN communication.
The air conditioning amplifier reads the difference between compressor speed and engine speed. When the difference becomes too large, the air conditioning amplifier determines that the compressor is locked, and turns the magnetic clutch off.
