Fail-safe

FAIL-SAFE CONTROL BY DTC

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



REAR WIPER MOTOR PROTECTION


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 BY LIGHT AND RAIN SENSOR MALFUNCTION

BCM detects the light and rain sensor serial link error and the light and rain sensor malfunction.

BCM controls the following fail-safe when light and rain sensor has a malfunction.

Fail-safe Control
• Auto light control: Headlamp low beam, parking lamp, license plate lamp and tail lamp are turned ON.

• Front wiper control
- Front wiper switch AUTO and sensing rain drop: The condition just before the activation of fail-safe is maintained 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
