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.
