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

DTC Index

INFOID:0000000004422043

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.
