Fail-safe

INFOID:0000000010741736

FAIL-SAFE CONTROL BY DTC

BCM performs fail-safe control when any DTC are detected.

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.

Shifting from “OFF status” to “Audio / navigation 
unavailable status”

Any of the following conditions is satisfied.
• Driver door is opened or closed.
• The steering lock operates.

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 BY RAIN SENSOR MALFUNCTION

BCM detects the rain sensor serial link error and the rain sensor malfunction.
BCM controls the following fail-safe when rain sensor has a malfunction.
• Front wiper switch AUTO and sensing rain drop: The condition just before the activation of fail-safe is main-

tained until the front wiper switch is turned OFF.

• Front wiper switch AUTO and not sensing rain drop: Front wiper is LO operation until the front wiper switch is

turned off.

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.
