Module, Heated Seat
WARNING: This page is about a different car, the 2007 Jeep Patriot and 2007 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
The heated seat module (2) is located under the left front seat. It has a single electrical connector (1) and a push pin style retainer that secures it to the seat pan. The module can be accessed from under the front left seat with the seat in the full back position.
The heated seat module is a microprocessor designed to use the Local Interface Network (LIN) data bus messages from the instrument cluster also known as the Cabin Compartment Node (CCN). The CCN receives inputs from the heated seat switches and in turn signals the heated seat module to operate the heated seat elements for both front seats.
