PROCEDURES INITIAL
FOLLOW THESE STEPS WHEN BEGINNING ANY SRS
SERVICE:
1. Check the SRS fuses (multi-purpose fuses No. 11 and
No. 18).
If either is loose, tighten it; if damaged or blown, replace
it.
2. After performing step 1, turn the ignition key to the “ON”
position. Does
warning light illuminate for about
7 seconds and then turn OFF? If yes, SRS system is
functioning properly.
If no, continue with following steps.
NOTE
1.
From 1993 model, the SRS warning light illuminates
also when the battery voltage drops. In that case,
the SRS warning light goes out if the battery voltage
returns to the normal level.
2.
On 1992 model, if the vehicle has a discharged battery
or battery power supply (multi-purpose fuses No. 11
or No. 18) is disconnected with the ignition key in
the “ON” position, the SRS warning light will continue
to illuminate even after the battery is recharged or
the fuses are replaced in
original positions. In
this case, the SRS warning light can be extinguished
by turning the ignition switch ON and OFF 10 times.
