Fail-safe
INFOID:0000000009268689
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.
DTC Inspection Priority Chart
INFOID:0000000009268690
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
