BCM (BODY CONTROL MODULE)
Fail-safe
INFOID:0000000006627749
FAIL-SAFE CONTROL BY DTC
BCM performs fail-safe control when any DTC are detected.
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 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.
REAR WIPER MOTOR PROTECTION
BCM detects the rear wiper stopping position according to the rear wiper auto stop signal.
When the rear wiper auto stop signal does not change more than 5 seconds while driving the rear wiper, BCM
stops power supply to protect the rear wiper motor.
Condition of cancellation
1.
Pass more than 1 minute 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
INFOID:0000000006627750
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
