Distribution System

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

The distribution system consists of a network of air ducts that supply air from the distribution outlets of the auxiliary climate control assembly to the vents installed in:

The headliner, above each rear door
The left and right C pillar trim panel
The carpet, below the left and right rear seats.

The vents in the headliner are adjustable, those in the side bolsters and the carpet are fixed.

Four duct air temperature sensors are installed in the air ducts. One in each duct to the left and right vents in the headliner. One in the duct to the left vents in the seat side bolsters and carpet. One in the duct to the right vents in the seat side bolsters and carpet. The sensors are Negative Temperature Coefficient (NTC) thermistors, which are connected to the Rear Integrated Control Panel (RICP). The Automatic Temperature Control Module (ATCM) uses the data from the sensors in output temperature calculations for the related ducts.
