WCS BCM (BODY CONTROL MODULE) WCS-67 < ECU DIAGNOSIS INFORMATION > C D E F G H I J K L M B A O P HIGH FLASHER OPERATION BCM detects the turn signal lamp circuit status by the current value. 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 sen- sor 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: ⇒ ON and front wiper switch is INT/ AUTO position, BCM operates a fail-safe control. REAR WIPER MOTOR PROTECTION BCM detects the rear wiper stopping position according to the rear wiper stop position signal. Condition of cancellation 1. More than 1 minute is passed after the rear wiper stop. 2. Turn rear wiper switch OFF. 3. Operate the rear wiper switch or rear washer switch.
