PRECAUTIONS
E915C2A3
GENERAL PRECAUTIONS
Please read the following precautions carefully before per-
forming the airbag system service. Observe the instruc-
tions described in this manual, or the airbags could acci-
dentally deploy and cause damage or injuries.
• Except when performing electrical inspections, al-
ways turn the ignition switch OFF and disconnect
the negative cable from the battery, and wait at least
three minutes before beginning work.
NOTE
The contents in the memory are not erased even if the
ignition switch is turned OFF or the battery cables are
disconnected from the battery.
• Use the replacement parts which are manufactured to
the same standards as the original parts and quality.
Do not install used SRS parts from another vehicle.
Use only new parts when making SRS repairs.
• Carefully inspect any SRS part before you install it.
Do not install any part that shows signs of being
dropped or improperly handled, such as dents,
cracks or deformation.
ERKD002V
• Before removing any of the SRS parts (including the
disconnection of the connectors), always disconnect
the SRS connector.
AIRBAG HANDLING AND STORAGE
Do not disassemble the airbags; it has no serviceable
parts. Once an airbag has been deployed, it cannot be
repaired or reused.
For temporary storage of the air bag during service, please
observe the following precautions.
• Store the removed airbag with the pad surface up.
• Keep free from any oil, grease, detergent, or water to
prevent damage to the airbag assembly.
ERKD002Z
• Store the removed airbag on secure, flat surface away
from any high heat source (exceeding 85 C/185 F).
• Never perform electrical inspections to the airbags,
such as measuring resistance.
• Do not position yourself in front of the airbag assembly
during removal, inspection, or replacement.
• Refer to the scrapping procedures for disposal of the
damaged airbag.
• Be careful not to bump or impact the SRS unit or the
side impact sensors whenever the ignition switch is
ON, wait at least three minutes after the ignition switch
is turned OFF before begin work.
• During installation or replacement, be careful not to
bump (by impact wrench, hammer, etc.)
the area
around the SRS unit and the side impact sensor. The
airbags could accidentally deploy and cause damage
or injury.
• After a collision in which the airbags were deployed,
replace the front airbags and the SRS unit. After a
collision in which the side airbag was deployed, re-
place the side airbag, the front impact sensor and side
impact sensor on the side where the side airbag de-
ployed and the SRS unit. After a collision in which the
airbags or the side air bags did not deploy, inspect for
any damage or any deformation on the SRS unit and

the side impact sensors. If there is any damage, re-
place the SRS unit, the front impact sensor and/or the
side impact sensors.
• Do not disassemble the SRS unit, the front impact
sensor or the side impact sensors
• Turn the ignition switch OFF, disconnect the battery
negative cable and wait at least three minutes before
beginning installation or replacement of the SRS unit.
• Be sure the SRS unit, the front impact sensor and
side impact sensors are installed securely with the
mounting bolts.
• Do not spill water or oil on the SRS unit,or the front
impact sensor or the side impact sensors and keep
them away from dust.
• Store the SRS unit, the front impact sensor and the
side impact sensors in a cool (less than 40 C/104 F)
and dry (less than 80% relative humidity, no moisture)
area.
WIRING PRECAUTIONS
SRS wiring can be identified by special yellow outer cov-
ering (except the SRS circuits under the front seats).
Observe the instructions described in this section.
• Never attempt to modify, splice, or repair SRS wiring.
If there is an open or damage in SRS wiring, replace
the harness.
ERKD002Y
• Be sure to install the harness wires so that they are
not pinched, or interfere with other parts.
ERKD002X
• Make sure all SRS ground locations are clean, and
grounds are securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent
problems that are difficult to diagnose.
PRECAUTIONS FOR ELECTRICAL INSPECTIONS
• When using electrical test equipment, insert the probe
of the tester into the wire side of the connector.
Do not insert the probe of the tester into the terminal
side of the connector, and do not tamper with the con-
nector.
ERKD002W
• Use a u-shaped probe.
Do not insert the probe
forcibly.
• Use specificed service connectors for troubleshoot-
ing.

RESTRAINTS
Using improper tools could cause an error in inspec-
tion due to poor metal contact.
AIRBAG CONNECTOR
DISCONNECTING
To release the lock, pull the spring-loaded sleeve (A) and
the slider (B), while holding the opposite half of the con-
nector. Pull the connector halves apart. Be sure to pull on
the sleeve and not on the connector half.

WARNING LAMP ACTIVATION
E2B5F9DA
WARNING LAMP BEHAVIOR AFTER IGNITION ON
As soon as the operating voltage is applied to the SRSCM
ignition input, the SRSCM activates the warning lamp for
a bulb check.
The lamp shall turn on for 6 seconds during the initializa-
tion phase and be turned off afterward. However, in order
to indicate the driver, the warning lamp shall turn on for 6
seconds and off for one second then on continuously after
the operating voltage is applied if any active fault exists.

SRSCM INDEPENDENT WARNING LAMP
ACTIVATION
There are certain fault conditions in which the SRSCM
cannot function and thus cannot control the operation of
the standard warning lamp. In these cases, the standard
warning lamp is directly activated by appropriate circuitry
that operates independently of the SRSCM. These cases
are:
1.
Loss of battery supply to the SRSCM : warning lamp
turned on continuously.
2.
Loss of internal operating voltage : warning lamp
turned on continuously.
3.
Loss of Microprocessor operation : warning lamp
turned on continuously.
4.
SRSCM not connected : warning lamp turned on con-
tinuously through the shorting bar.

PASSENGER AIRBAG DEACTIVATION (PAD) LAMP
OPERATION
The SRSCM is designed with circuitry and software to
drive a PAD lamp, which is used for depowered airbag sys-
tem. For the PAD indicator circuitry to function properly,
both the SRSCM and PAD indicator are sourced from the
same ignition line. After ignition on, the PAD indicator will
be turned on for 4 seconds and off for 3 seconds during
the initialization phase. Thereafter the lamp will be turned
on as long as the PAD switch is in the disabled position.
