OPERATION CHECK

CHECK WINDSHIELD DEICER SYSTEM

NOTICE:

If the windshield deicer 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 windshield deicer 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.
