SRS – Post-collision Diagnosis52B-20
REPAIR PROCEDURE
WHEN AIR BAG DEPLOYS IN A COLLISION.
1. Replace the following parts with new ones.

SRS-ECU (Refer to P.52B-24.)

Air bag module (Refer to P.52B-25.)
2. Check the following parts and replace if there are any
malfunctions.

Clock spring (Refer to P.52B-25.)

Steering wheel, steering column and intermediate
joint
(1) Check wiring harness (built into steering wheel)
and connectors for damage, and terminals for
deformation.
(2) Install air bag module to check fit or alignment
with steering wheel.
(3) Check steering wheel for noise, binds or difficult
operation and excessive free play.
3. Check harnesses for binding, connectors for damage,
poor connections, and terminals for deformation.
(Refer to P.52B-18.)
WHEN AIR BAG DOES NOT DEPLOY IN LOW-SPEED
COLLISION.
Check the SRS components. If the SRS components are
showing any visible damage such as dents, cracks, or
deformation, replace them with new ones. Concerning parts
removed for inspection, replacement with new parts and
cautionary points for working, refer to appropriate INDIVIDUAL
COMPONENT SERVICE, P.52B-22.

SRS – Post-collision Diagnosis / Individual Component Service52B-22
Steering wheel, steering column and intermediate joint
1. Check wiring harness (built into steering wheel) and
connectors for damage, and terminals for deformation.
2. Install air bag module to check fit or alignment with steering
wheel.
3. Check steering wheel for noise, binds or difficult operation
and excessive free play.
Harness connector (body wiring harness)
Check harnesses for binding, connectors for damage, poor
connection, and terminals for deformation. (Refer to P.52B-18.)
INDIVIDUAL COMPONENT SERVICE
If the SRS components are to be removed or replaced as a result of maintenance, troubleshooting,
etc., follow each procedure (P.52B-24 – P.52B-31)
Caution
1. SRS components should not be subjected to hear over 93C, so remove the SRS-ECU, air
bag module and clock spring before drying or baking the vehicle after painting.
Recheck SRS system operability after re-installing them.
2. If the SRS components are removed for the purpose of check, sheet metal repair, painting,
etc., they should be stored in a clean, dry place until they are reinstalled.

SRS – Air Bag Module Disposal Procedures52B-33
3. Peform the following procedure to deploy each air bag
module.
<Air bag module (driver’s side)>
(1) Remove the steering column cover lower.
(2) Remove the connection between the clock spring
2-pin connector (red) and the body wiring harness
connector.
NOTE
If the clock spring connector is disconnected from
the body wiring harness, both electrodes of the clock
spring connector will be automatically shorted to
prevent unintended deployment of the air bag due
to static electricity, etc.
(3) Connect two wires, each six meters or longer, to the
two leads of SRS air bag adapter harness A and
cover the connections with insulation tape. The other
ends of the two wires should be connected to each
other (short-circuited), to prevent sudden unexpected
deployment of the air bag.
(4) Connect the clock spring or air bag module (front
passenger’s side) 2-pin connector (red) to SRS air
bag adapter harness A and pass the deployment
wires out of the vehicle.
(5) Shut all the doors with their window glasses closed
and cover the vehicle with a body cover to suppress
explosion noise leaks as much as possible.
Caution
Be sure to wrap the vehicle entirely in a body cover,
otherwise damaged glass panes could break into
fragments, bringing about a very dangerous situation.
(6) At a location as far away from the vehicle as possible,
disconnect the two connected wires from each other,
and connect them to the two terminals of the battery
(which has been removed from the vehicle) to deploy
the air bag.

SRS – Air Bag Module Disposal Procedures52B-35
<Air bag module (front passenger’s side)>
(1) Remove the glove box. (Refer to P.52B-27.)
(2) Remove the connection between the air bag module
(front passenger’s side) connector (red 2-pin) and
the body wiring harness connector.
(3) Connect two wires, each six meters or longer, to the
two leads of SRS air bag adapter harness A and
cover the connections with insulation tape. The other
ends of the two wires should be connected to each
other (short-circuited), to prevent sudden unexpected
deployment of the air bag.
(4) Connect the clock spring or air bag module (front

FULL-AUTOMATIC AIR CONDITIONER – Troubleshooting55-50
Inspection procedure 13
Condenser fan does not operate.
Probable cause
If the condenser fan does not turn when the A/C is ON, the cause is probably
a malfunction of the condenser fan motor activation circuit. In this case, reduced
cooling performance will be caused if the vehicle is not running.
