SUPPLEMENTAL RESTRAINT SYSTEM (SRS)PFP:28556
SRS ConfigurationEHS000CH
The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in the “ON” or “START”
position.
The collision modes for which supplemental restraint systems are activated are different among the SRS sys-
tems. For example, the driver air bag module and front passenger air bag module are activated in a frontal col-
lision but not in a side collision.
SRS configurations which are activated for some collision modes are as follows;
Front Seat Belt Pre-tensioner with Load LimiterEHS000CI
The seat belt pre-tensioner system with load limiter is installed to
both the driver's seat and the front passenger's seat. It operates
simultaneously with the SRS air bag system in the event of a frontal
collision with an impact exceeding a specified level.
When the frontal collision with an impact exceeding a specified level
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the pre-tensioner. Vehicle passengers are
securely restrained.
When passengers in a vehicle are thrown forward in a collision and
the restraining force of the seat belt exceeds a specified level, the
load limiter permits the specified extension of the seat belt by the
twisting of the ELR shaft, and a relaxation of the chest-area seat belt
web tension while maintaining force.

Trouble Diagnosis IntroductionEHS000CL
CAUTION:
●Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harness can be identified by yellow and/or orange harness connector.
●Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
●Keep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows:
NOTE:
Seat belt pre-tensioner malfunction is indicated by “AIR BAG” warning lamp.
HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.

TROUBLE DIAGNOSIS
NOTE:
●Follow the procedures in numerical order when repairing malfunctioning parts. Confirm whether malfunc-
tion is eliminated using air bag warning lamp or CONSULT-II each time repair is finished. If malfunction is
still observed, proceed to the next step. When malfunction is eliminated, further repair work is not
required.
●Follow the procedure in numerical order when repairing malfunctioning parts, then make the system
check.
●The screen contents are the same as the self-diagnosis results, "self-diagnosis results "SELF-DIAG
[CURRENT]" and "SELF-DIAG [PAST]".

Caution for Air Bag Module and Seat Belt Pre-tensioner EHS000DE
●Before disposing of air bag module and seat belt pre-tensioner, or vehicles equipped with such systems,
deploy the systems. If such systems have already been deployed due to an accident, dispose of them as
indicated in SRS-46, "
DISPOSING OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER"
●When deploying the air bag module and seat belt pre-tensioner, always use the Special Service Tool;
Deployment tool (KV99106400).
●When deploying the air bag module and seat belt pre-tensioner, stand at least 5 m (16 ft) away from the
deployment component.
●When deploying air bag module and seat belt pre-tensioner, a fairly loud noise is made, followed by
smoke being released. The smoke is not poisonous, however, be careful not to inhale smoke since it irri-
tates the throat and can cause choking.
●Always activate one air bag module at a time.
●Due to heat, leave air bag module unattended for more than 30 minutes after deployment. Also leave seat
belt pre-tensioner unattended for more than 10 minutes after deployment.
●Be sure to wear gloves when handling a deployed air bag module and seat belt pre-tensioner.
●Never apply water to the deployed air bag module and seat belt pre-tensioner.
●Wash your hands clean after finishing work.
●Place the vehicle outdoors with an open space of at least 6 m (20 ft) on all sides when deploying air bag
module and seat belt pre-tensioner while mounted in vehicle.
●Use a voltmeter to make sure the vehicle battery is fully charged.
●Do not dispose of the air bag module and seat belt pre-tensioner un-deployed.
CHECKING DEPLOYMENT TOOL
Connecting To Battery
CAUTION:
The battery must show voltage of 9.6V or more.
Remove the battery from the vehicle and place it on dry wood blocks
approximately 5 m (16 ft) away from the vehicle.
●Wait 3 minutes after the vehicle battery is disconnected before
proceeding.
●Connect red clip of deployment tool to battery positive terminal
and black clip to negative terminal.
Make sure the polarity is correct. The right side lamp in the tool,
marked “deployment tool power”, should glow with a green
light. If the right side lamp glows red, reverse the connections
to the battery.
Deployment Tool Check
Press the deployment tool switch to the “ON” position. The left side
lamp in the tool, marked “air bag connector voltage” should illumi-
nate. If it does not illuminate, replace the tool.
