Precautions
General Precautions
Please read the following precautions carefully before performing the airbag system service. Observe the instructions
described in this manual, or the airbags could accidentally deploy and cause damage or injuries. a. Except when performing electrical inspections, always turn the ignition switch OFF and disconnect the negative
cable from the battery, and wait at least three minutes before beginning work.
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.
b. 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.
c. 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.
d.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.
a. Store the removed airbag with the pad surface up.
b. Keep free from any oil, grease, detergent, or water to prevent damage to the airbag assembly.
Page 792 of 1575

c.Store the removed airbag on secure, flat surface away from any high heat source (exceeding 85°C/185°F).
d. Never perform electrical inspections to the airbags, such as measuring resistance.
e. Do not position yourself in front of the airbag assembly during removal, inspection, or replacement.
f. Refer to the scrapping procedures for disposal of the damaged airbag.
g. 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.
h. 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.
i. 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, replace the side airbag, the front impact sensor and side impact sensor on
the side where the side airbag deployed 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, replace the SRS unit, the front impact sensor and/or the side impact sensors.
j. Do not disassemble the SRS unit, the front impact sensor or the side impact sensors
k. 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.
l. Be sure the SRS unit, the front impact sensor and side impact sensors are installed securely with the mounting
bolts.
m. 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.
n. 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 covering (except the SRS circuits under the front seats).
Observe the instructions described in this section.
a. Never attempt to modify, splice, or repair SRS wiring.
If there is an open or damage in SRS wiring, replace the harness.

WARNING LAMP ACTIVATION
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 initialization 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. 1. Active fault or historical fault counter is greater or equal to 10
2.Normal or historical fault counter is less than 10
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 continuously 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 system.
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.
PASSENGER RESTRAINTS ACTIVATION WITH PAD SWITCH
The PAD switch affects the activation of the front passenger airbag only and the switch is controlled manually. The
PAD switch will be functioned as follows:
PAD Switch status PAD LampPAB
Phase- up ON → OFF Enable
Enabled position OFFEnable
Disabled position ONDisable
Fault Based on PABEnable
