Heated Seats

Heated seats system consists of the following components:

• Heated seat switch.
• Driver's heated seat relay module.
• Passenger's heated seat relay module.
• Driver's heated seat thermistor.
• Passenger's heated seat thermistor.
• Driver's back cushion heater element.
• Driver's seat cushion heater element.
• Passenger's back cushion heater element.
• Passenger's seat cushion heater element.
• HVAC/DIC/DRL/HEATED SEAT (10-amp) fuse.
• PWR/HEATED SEAT PSD (30-amp) circuit breaker.

Heated seats are controlled by heated seat switches and heated seat relay modules. Ignition voltage is supplied to heated seat switches. When a heated seat switch is turned on, voltage is supplied through heated seat switch signal circuits to heated seat relay module terminals "B" and "C". Battery voltage is supplied to heated seat relay modules. When heated seat switch is turned on, and resistance through heated seat thermistor is within acceptable limits, relay module closes battery supply circuit to seat heater element supply circuit. A temperature sensor, located in seat cushion, senses temperature of seat cushion and sends a signal to heated seat module to increase or decrease amount of current to seat cushion and seatback heating elements.
