< ECU DIAGNOSIS INFORMATION >

BCM

• *5: Without automatic back door system

Fail-safe

INFOID:0000000009651711

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.

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

INFOID:0000000009651712

If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
