Automatic Temperature Control Module (ATCM)

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The Automatic Temperature Control Module (ATCM) processes inputs from the Touch Screen (TS), the Integrated Control Panel (ICP) and the system sensors. In response to these inputs, the ATCM outputs control signals to the Air Conditioning (A/C) system and the heating and ventilation system.

Three electrical connectors provide the interface between the ATCM and the vehicle wiring. The ATCM uses hardwired inputs from the system sensors, the Local Interconnect Network (LIN) bus to communicate with the recirculation, temperature blend, distribution and center face vent motors, and the medium speed CAN (controller area network) bus to communicate with other control modules on the vehicle.

Three electrical connectors provide the interface between the ATCM and the vehicle wiring. The ATCM uses hardwired inputs from the system sensors and the High Speed (HS) Controller Area Network (CAN) comfort systems bus to communicate with other control modules on the vehicle.

The ATCM uses Local Interconnect Network (LIN) bus connection to communicate with the following:

Recirculation motor
Temperature blend motor
Air distribution motor
Center face vent motor.

In addition to controlling the A/C system and the heating and ventilation system, the ATCM also controls the following:
