Engine unit troubleshooting
If the multifunction meter is turned on before the problem is solved, the information display will indicate
the diagnostic code "c" and the "WARNING" indicator light "a" will blink. If the engine is started, the
"WARNING" indicator light "a" and the check engine warning indicator "b" blink and the buzzer sounds
intermittently for 30 seconds.
When the engine is started for the first time after the problem is solved, the "WARNING" indicator light
and the check engine warning indicator blink and the buzzer sounds intermittently for 30 seconds to
indicate that malfunction history exists.
TIP:
Because the multifunction meter cannot display more than 1 diagnostic code even if there are multiple
diagnostic codes, using the YDIS is recommended.
