FAIL-SAFE CONTROL BY DTC

BCM performs fail-safe control when any DTC are detected.

REAR WIPER MOTOR PROTECTION

BCM detects the rear wiper stopping position according to the rear wiper auto stop signal.
When the rear wiper auto stop signal does not change more than 5 seconds while driving the rear wiper, BCM
stops power supply to protect the rear wiper motor.

Condition of cancellation

1.

Pass more than 1 minute after the rear wiper stop.

2.

Turn rear wiper switch OFF.

3.

Operate the rear wiper switch or rear washer switch.
