DESCRIPTION
This circuit consists of the air conditioning control assembly and the A/C amplifier. When the air conditioning control assembly is operated, signals are transmitted to the A/C amplifier through the LIN communication system.
If the LIN communication system malfunctions, the A/C amplifier does not operate even if the air conditioning control assembly is operated.
