NOTE:  If any SRS components are damaged, they 
must be replaced.  If SRS component mounting points 
are damaged, they must be replaced.

• Never use SRS parts from another vehicle.  This 

does not include remanufactured parts purchased 
from an authorized dealer; they may be used for SRS 
repairs.

• Do not attempt to service the SDM, the SRS coil 

assembly, or the air bag assembly.  Service of these 
items is by replacement only.

• Verify the part number of replacement air bag 

assembly.

CAUTION:  Never use the air bag assembly from 
another vehicle.
Use only the air bag assembly for UE models.

CAUTION:  Proper operation of the sensors and 

Supplemental Restraint System (SRS) requires that 
any repairs to the vehicle structure return it to the 
original production configuration.  Deployment 
requires, at a minimum, replacement of the SDM, air 
bag assembly and dimensional inspection of the 
steering column.  Any visible damage to the SDM 
mounting bracket (s) requires replacement, and the 
steering column must be dimensionally inspected, 
whether deployment occurred or not.

Metal Pin) Damage

If any connector or terminal in the SRS wire harness 
(except pigtails) is damaged, it should be replaced.

SRS Wire Pigtail Damage

If the wiring pigtail (a wire or wires attached directly to 
the device, not by a connector) is damaged, the entire 
component (with pigtail) must be replaced.  Examples of 
“pigtail" components are the driver air bag assembly, the 
passenger air bag assembly, and the SRS coil 
assembly.

On–Vehicle Service

Service Precautions

WARNING:  WHEN PERFORMING SERVICE ON OR 
AROUND SRS COMPONENTS OR SRS WIRING, 
FOLLOW THE PROCEDURES LISTED BELOW TO 
TEMPORARILY DISABLE THE SRS.  FAILURE TO 
FOLLOW PROCEDURES COULD RESULT IN 
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL 
INJURY OR OTHERWISE UNNEEDED SRS REPAIRS.
The SDM in Driver—Passenger SRS can maintain 
sufficient voltage to cause a deployment for up to 15 
seconds after the ignition switch is turned “OFF", the 
battery is disconnected, or the fuse powering the SDM 
is removed.
Many of the service procedures require removal of the 
“SRS" fuse, and disconnection of the air bag assembly 
from the deployment loop to avoid an accidental 
deployment.  If the air bag assembly is disconnected 
from the deployment loop as noted in the “Disabling the 
SRS" procedure that follows, service can begin 
immediately without waiting for the 15 second time 
period to expire.

Disabling The SRS

Removal

Turn the ignition switch to “lock" and remove key.

1. Remove SRS fuse “METER” and “SRS”, from left 

dash side lower fuse block or disconnect battery.

2. Disconnect yellow 2–pin connector at the base of 

steering column. 

3. Remove glove box assembly, Refer to “Passenger 

Air Bag Assembly Replacement" in section.

4. Disconnect yellow 2–pin connector behind the glove 

box assembly.

CAUTION:  With the “SRS" fuse removed and 
ignition switch “ON", “AIR BAG" warning lamp will 
be “ON". This is normal operation and does not 
indicate an SRS malfunction.

Enabling The SRS

Installation

CAUTION:  Never use the air bag assembly from 
another vehicle. Use only the air bag assembly for 
UE models.
Turn ignition switch to “LOCK" and remove key.

1. Connect yellow 2–pin connector passenger air bag 

assembly.

2. Install glove box assembly, refer to “Passenger Air 

Bag Assembly Replacement" in section.

3. Connect yellow 2–pin connector at the base of 

steering column.

4. Install “AIR BAG" fuse “METER” and “SRS” to left 

dash side lower fuse block or connect battery.

Turn ignition switch to “ON" and verify that the “AIR 

SECTION

BAG" warning lamp flashes seven times and then turns 
“OFF" If it does not operate as described, perform the 
“Supplemental Restraint System (SRS) Diagnostic 
System Check" in section.

Handling / Installation / Diagnosis

1. Air bag assembly should not be subjected to 

temperatures above 93

°

C (200

°

F

).

2. Air bag assembly, and Sensing and Diagnostic 

Module (SDM) should not be used if they have been 
dropped from a height of 100 centimeters (3.28 
feet).

3. When a SDM is replaced, it must be oriented with 

the arrow on the sensor pointing toward the front of 
the vehicle.  It is very important for the SDM to be 
located flat on the mounting surface, parallel to the 
vehicle datum line.  It is important that the SDM 
mounting surface is free of any dirt or other foreign 
material.

4. Do not apply power to the SRS unless all 

components are connected or a diagnostic chart 
requests it, as this will set a diagnostic trouble code.

5. The “SRS Diagnostic System Check" must be the 

starting point of any SRS diagnostics.  The “SRS 
Diagnostic System Check" will verify proper “AIR 
BAG" warning lamp operation and will lead you to 
the correct chart to diagnose any SRS malfunctions. 
Bypassing these procedures may result in extended 
diagnostic time, incorrect diagnosis, and incorrect 
parts replacement.

Air Bag Assembly Handling / 
Shipping / Scrapping

Live (Undeployed) Air Bag Assembly

Special care is necessary when handling and storing a 
live (undeployed) air bag assembly.   The rapid gas 
generation produced during deployment of the air bag 
could cause the air bag assembly, or an object in front of 
the air bag assembly, to be thrown through the air in the 
unlikely event of an accidental deployment.

827RX037

WARNING:  WHEN CARRYING A LIVE AIR BAG 
ASSEMBLY, MAKE SURE THE BAG OPENING IS 
POINTED AWAY FROM YOU.   IN CASE OF AN 
ACCIDENTAL DEPLOYMENT, THE BAG WILL THEN 
DEPLOY WITH MINIMAL CHANCE OF INJURY.   
NEVER CARRY THE AIR BAG ASSEMBLY BY THE 
WIRES OR CONNECTOR ON THE UNDERSIDE OF 
THE MODULE.

Air Bag Assembly Shipping Procedure For 
Live (Undeployed) Air Bag Assemblies

Service personnel should refer to the latest Service 
Bulletins for proper Supplemental Restraint System 
(SRS) air bag assembly shipping procedures.

Deployed Air Bag Assembly

“You should wear gloves and glasses. After the air bag 
assembly has been deployed, the surface of the air bag 
may contain solid particulate. This solid particulate 
consists primarily of by products of the chemical 
reaction, Potassium Chloride and copper metal dust. 
Compounds of Potassium Borate, Strontium Chloride, 
Copper Chloride, and Ammounium Chloride may be 
found in amounts of about 1% (each) of the total 
particulate.”

Air Bag Assembly Scrapping Procedure

During the course of a vehicle's useful life, certain 
situations may arise which will necessitate the disposal 
of a live (undeployed) air bag assembly.  This 
information covers proper procedures for disposing of a 
live air bag assembly.
Before a live air bag assembly can be disposed of, it 
must be deployed.  Alive air bag assembly must not be 
disposed of through normal refuse channels.

WARNING:  FAILURE TO FOLLOW PROPER SRS 
AIR BAG ASSEMBLY DISPOSAL PROCEDURES 
CAN RESULT IN AIR BAG DEPLOYMENT WHICH 
MAY CAUSE PERSONAL INJURY.  AN UNDPLOYED 
AIR BAG ASSEMBLY MUST NOT BE DISPOSED OF 
THROUGH NORMAL REFUSE CHANNELS.  THE 
UNDEPLOYED AIR BAG ASSEMBLY CONTAINS 
SUBSTANCES THAT CAN CAUSE SEVERE ILLNESS 
OR PERSONAL INJURY IF THE SEALED 
CONTAINER IS DAMAGED DURING DISPOSAL.  
DISPOSAL IN ANY MANNER INCONSISTENT WITH 
PROPER PROCEDURES MAY BE A VIOLATION OF 
FEDERAL, STATE, AND / OR LOCAL LAW.
In situations which require deployment of a live air bag 
assembly module, deployment may be accomplished 
inside or outside the vehicle.   The method employed 
depends upon the final disposition of the particular 
vehicle, as noted in “Deployment Outside Vehicle" and 
“Deployment Inside Vehicle" in this section.

Cautions About Air Bag Deployment And 
Disposal

Failure to follow proper procedures could result in 
erroneous air bag deployment which may cause 
personal injury be sure to follow proper procedures.

1. Turn off (Lock) the ignition switch and disconnect the 

minus terminal of the battery, then start the work 15 
or more sec later. (Air bag is designed to work by 
the back-up power source even if the battery power 
source is cut off at vehicle collision).

2. Be sure not to disassemble the air bag.

3. Do not give an impact to the air bag and bring the air 

bag close to magnet. (The air bag could deploy 
unexpectedly).

4. Place the air bag with its trim cover up.

5. Do not let the air bag deploy directly on the floor. 

(The air bag may be blown off 20

 ∼ 

30 cm

 (

6.5 or 10 

feet)).

6. Be sure to install the air bag firmly to a deployment 

tool (fixing tool).

7. Set a battery 10 m (33 feet) or more away from the 

air bag.

8. Before disconnecting air bag harness, ground the 

worker by touching the vehicle outer panel with bare 
hand.

9. When connecting or disconnecting the harness, do 

not work just in front of the air bag.

10. As deployment gives rise to big sound, warn the 

people around against it. Further, try to reduce the 
sound by covering the steering wheel or tires, and 
shut the vehicle windows in case of deployment 
inside the vehicle.

11. As deployment generates smoke, select a well 

ventilated place. (In case of deployment indoors, 
avoid deployment just under a fire alarm, smoke 
sensor, and fluorescent lamps).

12. Be careful not to inhale the smoke after deployment.

13. If part of the vehicle glass is damaged, cover the 

vehicle with a car cover to prevent the glass from 
braking at the time of deployment.

14. Do not touch the air bag immediately after 

deployment, since it remains hot for 30 minutes.

15. Do not water the air bag immediately after 

deployment.

16. Wear safety glasses and gloves throughout the work 

and wash the glasses and gloves after the work.

17. Do not reuse the removed air bag for another 

vehicle. (Deployment characteristic is different with 
vehicle types).

Deployment Outside Vehicle (Driver Air 
Bag Assembly)

Deployment outside the vehicle is proper when the 
vehicle is to be returned to service.  This includes, for 
example, situations in which the vehicle will be returned 
to useful service after a functionally or cosmetically 
deficient air bag assembly is replaced.  Deployment and 
disposal of a malfunctioning air bag assembly is, of 
course, subject to any required retention period.
For deployment of a live (undeployed) air bag assembly 
outside the vehicle, the deployment procedure must be 
followed exactly.  Always wear safety glasses during this 
deployment procedure until a deployed air bag 
assembly is scrapped or until an undeployed air bag 
assembly is shipped.  Before performing the procedures 
you should be familiar with servicing the SRS and with 
proper handling of the air bag assembly.  Procedures
