< ECU DIAGNOSIS INFORMATION >
[XENON TYPE]
BCM (BODY CONTROL MODULE)
HIGH FLASHER OPERATION
BCM detects the turn signal lamp circuit status by the current value.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.
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:
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.
REAR WIPER MOTOR PROTECTION
BCM detects the rear wiper stopping position according to the rear wiper stop position signal.
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.
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.
