Fail-safe
Fail-safe control by dtc
Bcm performs fail-safe control when any dtc are detected.

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.
