Heated Seat Operation

Ignition voltage is supplied the heated seat switches. When a heated seat switch is turned on, voltage is supplied through the heated seat switch signal circuits to the heated seat relay module terminals B and C. Battery positive voltage is supplied the heated seat relay modules. When the heated seat switch is turned on and the resistance through the heated seat thermistor is within acceptable limits, the relay module closes the battery positive supply circuit to the seat heater element supply circuit.
