Module-Heated Seats: Description
WARNING: This page is about a different car, the 2005 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The heated seat module (3) is located under the right front seat (1). It has a single electrical connector (2) and four locking tabs that secure it to the mounting bracket (4). The module can be accessed from under the front right seat with the seat in the full back position. The mounting bracket (4) is bolted to the seat frame assembly (5)
The heated seat module is a microprocessor designed to use Controller Area Network (CAN) 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.
