Control Module Inputs

Technical Description
The main purpose of the ACC control module is to control the air conditioning system so that a comfortable cabin temperature is achieved as soon as possible after starting and then maintained throughout the journey.

The ACC control module consists of a display panel with pushbuttons and an integral control module. Cars equipped with ACC differ from cars equipped with A/C in that a number of sensors and actuator motors are added to the air conditioning system.
