BCM

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.

FAIL-SAFE CONTROL OF COMBINATION SWITCH READING FUNCTION CAUSED BY LOW
POWER SUPPLY VOLTAGE

If voltage of battery power supply lower, BCM maintains combination switch reading to the status when input
voltage is less than approximately 9 V.
NOTE:
When voltage of battery power supply is approximately 9 V or more, combination switch reading function
returns to normal operation.

DTC Inspection Priority Chart
