1. Immobilizer Control Module
8G-4 IMMOBILIZER CONTROL SYSTEM (IF EQUIPPED)
IMMOBILIZER CONTROL MODULE
Immobilizer Control Module is installed to the underside of the
instrument panel at the driver's seat side.
As main functions, Immobilizer Control Module checks matching
not only between the Transponder Code transmitted from the igni-
tion key and that registered in Immobilizer Control Module (Up to
4 different Transponder codes can be registered.) but also between
the ECM/Immobilizer Control Module code transmitted from
ECM / PCM and that registered in Immobilizer Control Module. In
addition, it has an on-board diagnostic system (self-diagnosis func-
tion) which is described in ªOn-Board Diagnostic System (Self-
Diagnosis Function)º in this section.
ECM / PCM
As main functions, ECM / PCM not only checks matching of ECM/
Immobilizer Control Module code but also has an on-board diag-
nostic system (self-diagnosis function) as described in ªOn-Board
Diagnostic System (Self-Diagnosis Function)º in this section.
For installation position of ECM / PCM, refer to Section 6E1 or 6E2.
ON-BOARD DIAGNOSTIC SYSTEM

BACK DOOR / REAR GATE ASSEMBLY
REMOVAL
1) Remove back door trim, and door / rear gate sealing cover, refer
to steps 1) to 4) of BACK DOOR LOCK ASSEMBLY in this sec-
tion.
2) Remove wire harness connector inside the back door / rear gate.
3) Remove back door / rear gate balancer (first at its door-side and
next at its body-side), as shown.
WARNING:
Handling of Back Door / Rear Gate Balancer (Damper)

Do not disassemble balancer because its cylinder is
filled with gas.

The gas itself is harmless but it may issue out of the
hole together with chips generated by the drill.
Therefore, be sure to wear goggle.

When discarding removed back door / rear gate balanc-
er (damper), use a 2 to 3 mm (0.08 to 0.12 in.) drill to
make a hole as shown.

Handle balancer carefully. Do not scar or scratch ex-
posed surface of its piston rod, and never allow any
paint or oil to stick to its surface.

Do not turn piston rod with balancer fully extended.
5) Remove back door / rear gate hinge bolts and back door / rear
gate.

10B-64 AIR BAG SYSTEM
ACCIDENT WITH OR WITHOUT DEPLOYMENT ± COM-
PONENT INSPECTIONS
Certain air bag and restraint system components must be in-
spected after any crash, whether the air bag deployed or not.
Those components are:

Steering column and shaft joints
± Check for length, damage and bend according to ªChecking
Steering Column for Accident Damageº in SECTION 3C1.

Steering column bracket and capsules
± Check for damage and bent.
If any faulty condition is found in above checks, replace faulty
part.

Steering wheel and driver air bag (inflator) module
± Check for damage or air bag (inflator) module fitness.
± Check trim cover (pad surface) for cracks.
± Check wire harness and connector for damage or tightness.
If any faulty condition is found in above checks, replace faulty
part.

Contact coil and combination switch assembly
± Check wire harness and connectors for damage or tightness.
± Check contact coil case for damage.
If any faulty condition is found in above checks, replace.

Instrument panel member and reinforcement
± Check for any distortion, bending, cracking or other damage.
If any faulty condition is found in above checks, replace.

10B-78 AIR BAG SYSTEM
DEPLOYMENT INSIDE VEHICLE
Use this procedure when scrapping the entire vehicle including the driver and passenger air bag (inflator) modules.
CAUTION:
When vehicle itself will be used again, deploy the air bag outside vehicle according to ªDeployment
Outside Vehicleº, for deploying it inside will cause the instrument panel, glove box and their vicinity
to be deformed.
Failure to observe this CAUTION may require unneeded vehicle inspection and repair.
WARNING:
Following precautions must be observed for this work. Failure to observe any of them may result in
personal injury.

To avoid an accidental deployment, this work should be performed by no more than one person.

The procedure should be followed strictly as described here.

Be sure to read ªService Precautionsº for the air bag (inflator) module beforehand.

Never connect deployment harness to any power source before connecting deployment harness to
the air bag (inflator) module. Deployment harness shall remain shorted and not be connected to a
power source until the air bag is to be deployed.

The air bag (inflator) module will immediately deploy the air bag when a power source is connected
to it. Wear safety glasses throughout this entire deployment and disposal procedure.

Wear suitable ear protection when deploying air bag. Also, advise those who are in the area close to
deployment site to wear suitable ear protection.

Do not deploy driver and passenger air bag (inflator) modules at the same time.
1) Turn ignition switch to ªLOCKº, remove key and put on safety
glasses.
2) Remove all loose objects from front seats and instrument panel.
3) [For driver air bag (inflator) module]
Disconnect contact coil connector (yellow connector) located
near the base of the steering column.
ii) Release locking of lock lever.
ii) After unlocked, disconnect to connector.
[For passenger air bag (inflator) module]
Remove glove box from instrument panel and disconnect pas-
senger air bag (inflator) module connector (yellow connector).
ii) Release locking of lock lever.
ii) After unlocked, disconnect to connector.

1. Stretch deployment harness to its full length
10 m (33 ft).
2. Drop cloth, blanket or similar item2

8) Route deployment harness out the vehicle.
9) Verify that the inside of the vehicle and the area surrounding
the vehicle are clear of all people and loose or flammable ob-
jects.
10) Stretch the deployment harness to its full length 10 m (33 ft).
11) Place a power source near the shorted end of the deployment
harness. Recommended application: 12 Volts minimum, 2
amps minimum. A vehicle battery is suggested.
12) Completely cover windshield area and front door window
openings with a drop cloth, blanket to similar item. This reduces
the possibility of injury due to possible fragmentation of the ve-
hicle's glass or interior.
13) Notify all people in the immediate area that you intend to deploy
the air bag (inflator) module.
NOTE:

When the air bag deploys, the rapid gas expansion will
create a substantial report. Wear suitable ear protection.
Notify all people in the immediate area that you intend to
deploy the air bag (inflator) module and suitable ear
protection should be worn.

After the air bag (inflator) module has been deployed, the
surface of the air bag may contain a powdery residue.
This powder consists primarily of cornstarch (used to lu-
bricate the bag as it inflates) and byproducts of the
chemical reaction.
WARNING:
Safety precautions must be observed when handling a
deployed air bag (inflator) module.

After deployment, the metal surfaces of the air bag (infla-
tor) module will be very hot. Do not touch the metal areas
of the air bag (inflator) module for about 30 minutes after
deployment.

Do not apply water, oil, etc. to deployed air bag (inflator)
module.

If the deployed air bag (inflator) module must be moved
before it is cool, wear gloves and handle by the air bag or
vinyl trim.
Failure to follow procedures may result in fire or personal
injury.

14) Notify all people in the immediate area that you intend to acti-
vate the seat belt pretensioner.
NOTE:

When the pretensioner activates, the rapid gas expan-
sion will create a substantial report. Wear suitable ear
protection. Notify all people in the immediate area that
you intend to activate the seat belt pretensioner and suit-
able ear protection should be worn.

When the pretensioner activates, the seat belt preten-
sioner may jump about 30 cm (1 ft) vertically. This is a
normal reaction of the seat belt pretensioner to the force
of the rapid gas expansion inside the pretensioner.
WARNING:
Safety precautions must be observed when handling
an activated seat belt pretensioner.

After activation, the metal surfaces of the seat belt
pretensioner will be very hot. Do not touch the metal
areas of the seat belt pretensioner for about 30 min-
utes after activation.

Do not place the activated seat belt pretensioner
near any flammable objects.

Do not apply water, oil, etc. to the activated seat belt
pretensioner.

If the activated seat belt pretensioner must be
moved before it is cool, wear gloves and handle it by
using nonmetal material.
Failure to follow procedures may result in fire or per-
sonal injury.
15) Separate the two banana plugs on the deployment harness.
16) Connect the deployment harness to the power source (12V ve-
hicle battery) to immediately activate the pretensioner.
17) Disconnect the deployment harness from power source (12V
vehicle battery) and short the two deployment harness leads
together by fully seating one banana plug into the other.
