INSTALLATION POINTS.
SRS-ECU INSTALLATION
Caution
The SRS may not activate SRS-ECU ‘is not
properly, which result in the SRS system not
ing properly in a collision.
POST-INSTALLATION INSPECTION
Reconnect the negative battery terminal. Turn the i gnition
key to the “ON” position. Does the warning light illumi-
nate for about 7 seconds, turn OFF and then remain OFF?
If yes, SRS system is functioning properly. If no, consult page

Check the SRS-ECU case and brackets for dents, crac ks
or deformation.
Check connector for damage, and terminals for defor ma-
tion.
Caution
If a dent, cracks, deformation or rust is discovered,
replace the SRS-ECU with a new one.

column covers and the air bag
check
wheel for noise, binds or difficult operation.
(2) Reconnect the negative battery terminal. Turn t he ignition
key to the “ON” position. Does “SRS” warning light
illuminate for about 7 seconds, turn OFF and then r emain

AIR BAG MODULE CHECK
If any improper part is found during the following inspection,
replace the air bag module with a
Dispose of the old one according to the specified p rocedure.
(Refer to
Caution
Never attempt to measure the circuit resistance of the
air bag module (squib) even if you are using the specified
tester. If the circuit resistance is measured with
accidental air bag deployment will result in seriou s per-
sonal injury.
(1) Check pad cover for dents, cracks or deformation.
(2)Check the air bag module for dents, cracks or defor mation.
(3) Check hooks and connectors for damage, terminal s for
deformation, and harness for binds.
(4) Check air bag inflator case for dents, cracks o r deforma-
tion.
Air bag module
Protective tube
(5) Install the air bag module on the steering whee l to check
alignment with the wheel.
CLOCK SPRING CHECK
If, as result of the following checks, even one abn ormal point
is discovered, replace the clock spring with a new one.
(1) Check connectors and protective tube for. damag e, and
terminals for deformation.
(2) Visually check the case for damage”
