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 ==> ON and front wiper switch is INT/AUTO position, BCM operates a fail-safe control.
