Heated Seats - Description






DESCRIPTION

WARNING: The front passenger seat assembly contains critical components that affect the front passenger airbag deployment. Correctly functioning front passenger seat components are critical for the Occupant Classification System (OCS) to properly classify the front passenger and calculate the proper airbag deployment. Unapproved modifications or service procedures to the front passenger seat assembly, its related components, or trim cover may inadvertently change the airbag deployment in case of a frontal crash. This could result in death or serious injury to the front seat passenger if the vehicle is involved in an accident. The following requirements must be strictly adhered to:
- Do not modify the front passenger seat assembly or components in any way.
- Do not modify the front seat center console or center position seat in any way.
- Do not use prior or future model year seat trim covers not designated for the specific model being repaired. Always use the correct seat trim cover specified for the vehicle.
- Do not replace the seat trim cover with an aftermarket trim cover.
- Do not add a secondary trim cover other than those approved by Chrysler/Mopar.
- At no time should any Supplemental Restraint System (SRS) component or SRS related component or fastener be modified or replaced with any part except those which are approved by Chrysler/Mopar.





Vehicles with the heated seat option can be visually identified by the heated seat switches. Two heated seat switches (3) for the front seats are located in the center stack (4) rear HVAC control unit (2). These two switches allow the driver and front seat passenger to select from two different levels of electrical seat heating (HI/LO). The front heated seat switches are an integral part of the HVAC control unit. If the switches are inoperative or damaged in any way the complete HVAC control assembly must be replaced, Front.





Vehicles with the rear heated seat option can be visually identified by the two heated seat switches (3) 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 available individually for service. If the switches are inoperative or damaged in any way they should be replaced, Second Row.

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. 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.
