Principles of Operation

Power Seat (Driver Only)

The 6-way power seat feature moves the seat in 6 possible directions. The base of the seat can be moved forward or rearward and the front or back of the base cushion can be moved up or down independently. The power seat feature operates independent of the position of the key.
The power seat motors are hard-wired to the seat control switch. The seat control switch circuits are normally closed. Each circuit is switched to voltage or ground (depending on which direction is commanded) when an adjustment position is selected.

Heated Seats

The dual automatic temperature control (DATC) module contains the heated seat control buttons and indicators. The heated seat system functions independently from the climate control system.
A heated seat relay is located underside of each heated seat cushion frame. There are 2 voltage supplies to the heated seat relay. Voltage is supplied from the smart junction box (SJB) to each heated seat relay coil when the ignition key is on. Ground is supplied to the opposite side of the driver or passenger relay coil by the respective heated seat relay drive output circuit from the DATC module when a heated seat switch button is pressed to energize the affected relay. This closes the relay contact to supply battery voltage from battery junction box (BJB) to the driver or passenger heater elements. The driver and passenger heater elements are directly connected to ground, completing the electrical circuit to heat the seats. The cushion and backrest heater elements are wired in series.
The heated seat will remain ON until the heated seat switch is pressed again or until ignition voltage is removed from the system.
