Caution / Notice / Hint

NOTE:
  • If the climate control seat system is operated when the auxiliary battery voltage is low, due to the electrical load limit control that gives voltage supply priority to the power steering system, the climate control seat system may not operate. In this case, check the vehicle control history (RoB) of the power steering system and check that "Battery Voltage Drop: X208F" is not stored before proceeding with troubleshooting.

    Refer to VEHICLE CONTROL HISTORY (RoB) [11/2023 - ]

  • Inspect the fuses for circuits related to this system before performing the following procedure.
