Normal Operation
There are 2 power supplies to the heated seat relay. One power supply energizes the relay and heated switch LED when the key is in the run position and the heated seat switch is activated. This closes the relay and power is provided to the heated seat elements through the other power circuit. If the heated seat switch is ON when the ignition is turned OFF, the heated seat switch will be ON when the ignition is turned back ON.

Possible Causes
An inoperative heated seat can be caused by:
- wiring, terminals or connectors.
- a faulty heated seat switch (EMTC module).
- a faulty heated seat relay.
- a faulty heated seat element.
