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.
