Fail-safe

INFOID:0000000009757382

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 Index

INFOID:0000000009757384

NOTE:

Details of time display

• CRNT: Displays when there is a malfunction now or after returning to the normal condition until turning igni-

tion switch OFF

→ ON again.

• 1 - 39: Displayed if any previous malfunction is present when current condition is normal. It increases like 1

→ 2 → 3...38 → 39 after returning to the normal condition whenever ignition switch OFF → ON. The counter

remains at 39 even if the number of cycles exceeds it. It is counted from 1 again when turning ignition switch

OFF

→ ON after returning to the normal condition if the malfunction is detected again.
