Caution / Notice / Hint

NOTE:

If the window defogger 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 window defogger 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 - ]
The window defogger system uses the CAN communication system and CXPI communication system. First, confirm that there are no malfunctions in the CAN communication system and CXPI communication system. Refer to How to Proceed with Troubleshooting.
