Where is the ACCM on an electronic A/C equipped hybrid?
A) It is part of the PCM
B) It is part of the TCM
C) On the evaporator behind the instrument panel
D) It is part of the air conditioning compressor
Answer (2)
The Ambient Control Module (ACCM) in an electronic A/C equipped hybrid vehicle is located on the evaporator behind the instrument panel, making option C correct. It plays a crucial role in managing the HVAC system by collecting data and optimizing performance. This module works in coordination with other vehicle control systems to provide efficient climate control.

The question is asking about the location of the ACCM in an electronic air conditioning system equipped in hybrid vehicles.
What is the ACCM?
The ACCM, or Air Conditioning Control Module, is a component used in hybrid vehicles to manage the air conditioning system. It is responsible for controlling various functions such as regulating temperature, controlling fan speed, and making adjustments based on sensor data to ensure efficient operation of the air conditioning system.
Location of ACCM:
In most electronic air conditioning systems in hybrid vehicles, the ACCM is integrated with other components that manage vehicle functions:
Option C: On the evaporator behind the instrument panel
The evaporator is a part of the air conditioning system where the refrigerant absorbs heat from the indoor air, cooling it down. The air conditioning control module is usually located near or on the evaporator because it needs to closely monitor the temperature and humidity and make real-time adjustments.
Explanation of Incorrect Options:
A) It is part of the PCM: The PCM (Powertrain Control Module) mainly deals with engine and transmission management and does not usually control the air conditioning system.
B) It is part of the TCM: The TCM (Transmission Control Module) controls the vehicle's transmission. It's not involved in managing the air conditioning system either.
D) It is part of the air conditioning compressor: The compressor is a mechanical component of the AC system that sorts refrigerant and builds pressure. The ACCM is not mechanically a part of the compressor but is electronically linked to it for control purposes.
