Inputs And Outputs

WARNING: This page is about a different car, the 2006 Land Rover Range Rover Sport. However, it is still accessible from the selected car via links, so may be relevant.

Four electrical connectors provide the interface between the automatic temperature control (ATC) module and the vehicle wiring.

The control system sensors provide hardwired inputs to the automatic temperature control (ATC) module. The automatic temperature control (ATC) module also uses the LIN (local interconnect network) bus to communicate with the door motors in the heater assembly, and the medium speed controller area network (CAN) bus to communicate with other control modules on the vehicle. Refer to Communications Network .
