Town & Country V6-3.8L (2009)
The heated seat system for this vehicle includes the following major components:
-
Heated Seat Elements - Eight carbon fiber heated seat elements are used per vehicle, two for each heated seat. Two heated seat elements are
integral to each seat, one in the seat back and the other in the seat cushion. CAUTION: On vehicles equipped with heated cloth seats the
heating elements are an integral part of the seat foam and cover. If the heating element is damaged or inoperative the complete seat
cushion/cover or seat back/cover assembly must be replaced. Refer to the appropriate procedures.
-
Heated Seat Module - One heated seat module is used per vehicle. The Heated Seat Module is mounted under the Driver front seat. This module
contains the control logic and software for the front and 2nd row heated seat system. The module communicates on the Local Interconnect
Network (LIN) data bus.
-
Front Heated Seat Switches - Two heated seat switches for the front seats are located in the center stack rear HVAC control unit. These two
switches allow the driver and front seat passenger to select from two different levels of electrical seat heating (HI/LO).
-
Rear Heated Seat Switches - Two heated seat switches for the rear seats are located in the sliding door trim panels (6). The sliding door trim
panel mounted switches control the 2nd row heated seats. These switches allow the 2nd row seat passengers to select from two different levels of
electrical seat heating (HI/LO). The 2nd row heated seat switches are hardwired to the rear door modules.
-
Rear Door Modules - A door module is concealed behind the trim panel of each sliding door. The rear door modules each utilize integrated
circuitry and information carried on the CAN data bus network. In regards to the 2nd row heated seat system, the modules communicate between
the hardwired heated seat switches and the instrument cluster. The cluster then transfers the information to the heated seat module. See: Doors,
Hood and Trunk/Trunk / Liftgate/Power Trunk / Liftgate Control Module/Description and Operation/Power Liftgate Control Module - Description
for additional information.
-
ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) - The instrument cluster utilizes
integrated software and information carried on the LIN and CAN data bus. The instrument cluster serves as the link between the heated seat
switches and the heated seat module.
For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector
repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness
connectors, splices and grounds.
