SRS – Air Bag Module Disposal Procedures52B-32
AIR BAG MODULE DISPOSAL PROCEDURES
Before disposing of an air bag or a vehicle which
is equipped with it, the procedures below are to
be followed to deploy them.
UNDEPLOYED AIR BAG MODULE DISPOSAL
PROCEDURES
Caution
1. If the vehicle is to be scrapped or otherwise disposed
of, deploy the air bags inside the vehicle. If the vehicle
will continue to be used and only the air bag modules
are to be disposed of, deploy the air bags outside
the vehicle.
2. Since a large amount of smoke is produced when
the air bag is deployed, avoid residential areas
whenever possible.
3. Since there is loud noise when the air bags are
deployed, avoid residential areas whenever possible.
If anyone is nearby, give warning of the impending
noise.
4. Suitable ear protection should be worn by personnel
performing these procedures or by people in the
immediate area.
DEPLOYMENT INSIDE THE VEHICLE
(when disposing of a vehicle)
1. Move the vehicle to an isolated spot.
2. Disconnect the negative (–) and positive (+) battery cables
from the battery terminals, and then remove the battery
from the vehicle.
Caution
Wait at least 60 seconds after disconnecting the
battery cables before doing any further work.
(Refer to P.52B-3.)

INSPECTION PROCEDURE FOR TROUBLE SYMPTOMS
Inspection Procedure 1
Key hole illumination lamp remains illuminated.
Probable cause
The cause is probably a harness short or a defective ETACS-ECU or buzzer ECU.
Malfunction of harness wire

Malfunction of ETACS-ECU

Malfunction of buzzer ECU
Disconnect the ignition key cylinder illumination lamp connector
B-84 and measure the continuity:

Between 4 and body earth
OK:ConductingNGCheck the harness wire between the ignition key cylinder illumination
lamp and junction block, and repair if necessary.
OK
Replace the ETACS-ECU or buzzer ECU.
Inspection Procedure 2
Even if driver’s side door is opened, key hole illumination
lamp does not illuminate.
Probable cause
The cause is probably a defective key hole illumination lamp circuit system, or a
defective driver’s side door switch input circuit system if the ignition key reminder
warning buzzer is also faulty.
Malfunction of driver’s side door switch

Malfunction of bulb

Malfunction of connector

Malfunction of harness wire

Inspection Procedure 3
While key hole illumination lamp is illuminated, ignition
key is turned to the ON position but key hole illumination
lamp does not switch off. (However, it switch off after 15
seconds.)
Probable cause
While the key reminder warning buzzer is sounding, the
ignition key is turned to the ON position but the sound
dose not stop. (However, it stops when the driver’s side
door is closed.)
The cause is probably a malfunction of the ignition switch input circuit, ETACS-ECU
or buzzer ECU. Furthermore, if there is a malfunction of a multipurpose fuse, the
cause may also be a short circuit in a harness.
