CHECK WINDOW DEFOGGER SYSTEM
Turn the power switch on (IG).
Check that the rear window defogger wire becomes warm by operating the rear window defogger switch of the radio receiver assembly.
When the vehicle is stopped, confirm that the rear window defogger system operation stops after approximately 15 minutes.
If the auxiliary battery voltage becomes low, rear window defogger system operation is canceled to prioritize supplying power to the power steering system (Click here).
