The Automatic HVAC system has the option of being configured with either a manual or automatic auxiliary system. The number of auxiliary HVAC controls is dependent upon whether or not the vehicle is equipped with a sunroof (CF5). An automatic auxiliary HVAC system is only available with an automatic primary HVAC system without a sunroof. A manual auxiliary HVAC system is only available with an automatic auxiliary primary HVAC system with a sunroof.
The automatic primary and auxiliary HVAC systems communicate using keyboard data display (KDD) protocol. The automatic primary system communicates with the rear auxiliary HVAC control module. The manual auxiliary system is independent of the automatic primary HVAC system.
