PRE–CHECK
1.
SRS WARNING LIGHT CHECK
(a)
Turn the ignition switch to ACC or ON and check that the
SRS warning light lights up.
(b)
Check that the SRS warning light goes out after approx.
6 seconds.
HINT:
When the ignition switch is at ACC or ON and the SRS
warning light remains on or flashes, the airbag sensor as-
sembly has detected a malfunction code.
If, after approx. 6 seconds have elapsed, the SRS warn-
ing light sometimes lights up or the SRS warning light
lights up even when the ignition switch is OFF, a short in
the SRS warning light circuit can be considered likely.
Proceed to ”SRS warning light circuit malfunction” on
page
.

done using DLC2.
