Normal Operation
Upon receiving a signal from the electronic automatic temperature control (EATC) module, the heated seat module will decrease one setting (the sequence is HI, LO, OFF, HI, etc.). When the passenger heated seat is set to HI, both LED indicators above the passenger heated seat control button will illuminate. When the passenger heated seat is set to LO, only the left LED on the passenger heated seat indicator will illuminate. When the passenger heated seat is set to OFF, neither passenger heated seat LED will illuminate.

Possible Causes
An inoperative heated seat indicator can be caused by:
- wiring, terminals or connectors.
- a faulty heated seat module.
- a faulty EATC module.
