FAIL-SAFE CONTROL BY DTC

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






FAIL-SAFE CONTROL BY RAIN SENSOR MALFUNCTION

- BCM judges the rain sensor serial link error by the rain sensor serial link condition and detects the rain sensor malfunction by rain sensor malfunction signal.
- When BCM detects the rain sensor serial link error or the rain sensor malfunction while front wiper AUTO
operation, BCM operates a fail-safe control.
NOTE:
If rain sensor malfunction is detected when ignition switch is turned OFF (Right Arrow) ON and front wiper switch is INT
position, BCM operates a fail-safe control.

When the rear wiper stop position signal does not change for more than 5 seconds while driving the rear wiper, BCM stops power supply to protect the rear wiper motor.
1.More than 1 minute is passed after the rear wiper stops.
2.Turn rear wiper switch OFF.
