There are 2 blinking patterns for the air bag warning lamp. One is a 3-second blink followed by a 0.5- sec-
ond blink repeated. The other is two 1.5-second blinks followed by a 0.5-second blink repeated.

An Example of a 3-second Blink Followed by a 0.5-second Blink Repeated

a through b are repeated.

DIAGNOSIS SYSTEM (AIRBAG)

An Example of Two 1.5-second Blinks Followed by a 0.5-second Blink Repeated

a through b are repeated.
b: Six 0.5-second blinks indicate that the LH side curtain air bag module circuit is malfunctioning.

Number of 0.5-second blinks after Two 1.5-second blinks indicates malfunctioning items

HOW TO ERASE SELF-DIAGNOSTIC RESULTS

After a malfunction is repaired, turn the ignition switch OFF for at least one second, then turn ignition switch
ON. Diagnosis mode returns to the user mode. At that time the self-diagnosis result is cleared.
