• The SRS warning light goes off, and then
comes on again. This blinking pattern
indicates a source voltage drop. The SRS
warning light goes off 10 seconds after the
source voltage returns to normal.
(c) Review
(1) When the airbag system is normal:
The SRS warning light comes on only during the
primary check period (for approximately 6
seconds after the ignition switch is turned ON).
(2) When the airbag system malfunctions:
• The SRS warning light blinks after the
primary check period has elapsed.
• The SRS warning light goes off after the
primary check, but comes on again during the
constant check.
• The SRS warning light remains off even after
the ignition switch is turned from LOCK to
ON. However, if malfunctions such as an
open circuit have occurred in the wire
harness between the meter and ECU, the
warning light comes on 10 seconds after the
ignition switch is turned ON.
HINT:
The center airbag sensor keeps the SRS
warning light on if any malfunctions have been
detected in the airbag system.
