Heated Seat Relay
The Heated Seat System supply voltage is controlled through the Heated Seat Relay located in the Power Distribution Center (PDC). The relay coil is controlled by the Body Control Module (BCM) and is energized whenever the ignition key is in the on position. If low battery voltage is sensed by the Powertrain Control Module, a PCI bus message will be sent to the BCM to turn off the Heated Seat Relay.
