Passenger Airbag Module
Caution: Tampering with passenger airbag module
creates the risk of an injury from unexpected
deployment. Therefore, the passenger airbag
module should never be disassembled.
The passenger airbag module is on the passenger of
the instrument panel. The passenger airbag module
contains an igniter charge and a gas generator to inflate
the folded airbag.
The airbag contains a shorting bar, which short-circuit
the passenger high circuit to passenger low circuit when
the connector is disconnected. The shorting bar pre-
vents current from traveling through the passenger air-
bag module during servicing. The shorting bar is
disengaged when the connector is connected.
FRONT SEAT BELT PRETENSIONERS
Caution: Tampering with seat belt pretensioner
creates the risk of an injury from unexpected
deployment. Therefore, the seat belt pretensioner
should never be disassembled.
The seat belt pretensioners are assembled with each
front seat belt retractor to retract the seat belt webbing
when accounted a frontal collision. The seat belt preten-
tioners are controlled by sensing and diagnostic
Module (SDM).
The seat belt pretensioner contains an igniter charge
and a gas generator to pull the seat belt webbing. The
seat belt pretensioner must be replaced after an acci-
dent that causes its activation.
The seat belt pretensioner also contains a shorting bar
to prevent current from traveling through the seat belt
pretensioner during servicing. The shorting bar is
disengaged when the connector is connected.
SENSING AND DIAGNOSTIC
MODULE (SDM)
Caution: During the service procedures, be careful
when handling the SDM. Never shake or jar the
SDM. Never apply power to SRS when the SDM is
not rigidly attached to the vehicle. All SDM
mounting nuts and grounding nut must be fully
tightened. Failures to follow these precautions could
cause deployment and results in personal injury.
The SDM located on floor beneath the instrument panel.
The SDM performs the following functions:
Monitors the supplemental restraint system (SRS)
electrical components and sets a diagnostic trouble
code (DTC) when malfunction is detected.
Displays SRS diagnostic trouble codes and system
status information when connected to a scan tool.
Illuminates the airbag indicator to alert the driver to
any fault.
Provides a reserve power source to deploy the air-
bags and pretensioners if an accident has disabled
the normal power source.
Monitors vehicle velocity changes to detect frontal
impacts, which are severe enough to warrant deployment.
Causes current to flow through the airbag modules
and pretensioner to cause deployment if a frontal
impact of sufficient force is detected.
The SDM contains no user-serviceable parts.

SRS Diagnostic System Check
Caution: the sensing and diagnosis module (SDM)
can maintain sufficient voltage to deploy the airbags
and pretensioners for 0.15 seconds after the ignition
is OFF and the fuse has been removed. If the airbags
or pretensioners are not disconnected, do not begin
service until one minute has passed after
disconnecting power to the SDM. Otherwise, injury
could result.Caution: During service procedure, be very careful
when handling the SDM. Never strike or jar the SDM.
Never power the supplemental restraints system
(SRS) when the SDM is not rigidly attached to the
vehicle. Also SDM mounting nuts must be carefully
tightened to ensure proper operation of the SRS.
The SDM could be activated if it is powered when it
is not rigidly attached to the vehicle, resulting in
unexpected deployment and possible injury.

when the SRS Diagnostic System Check was previously
performed?
SENSING AND DIAGNOSTIC MODULE (SDM) INTEGRITY CHECK
The following diagnostic chart must be used when all
circuitry outside the sensing and diagnostic module
(SDM) has been found to operate properly, as indicated
by following the appropriate diagnostic trouble code
(DTC) chart. The chart verifies the need for SDM
replacement.
Circuit Description
When the SDM recognizes ignition voltage greater then
9 volts at terminal 5 of the SDM, the airbag indicator is
turns on for 4.5 seconds to verify operation. At this
time the SDM performs start-up tests followed by
resistance measurement tests and continues
monitoring tests. When malfunction is detected, the
SDM sets a current DTC and illuminates or blinks the
airbag indicator. When the malfunction is no longer
detected and/or the ignition switch is cycled, the SDM
will clear current DTCs and move them to a history file,
except for the DTCs 18, 24, 51, 53 and sometimes 71.
DTCs 18, 24, 51 and 53 will not clear using a scan tool
because these codes require replacement of SDM. The
SDM must be replaced only after the malfunction that
set the DTC has been repaired.Diagnostic Aids
The order in which DTCs are diagnosed is very
important. Failure to diagnose the DTCs in the order
specified may result in extended diagnostic time,
incorrect diagnosis, and incorrect parts replacement.
Test Description
The numbers below refer to steps on the diagnostic
table.
1. This test confirms a current malfunction. If no current
malefaction is occurring, refer to “Diagnostic Aids”
for the appropriate DTC. The SDM should not be
replaced for a historic DTC except when directed.
2. This test checks for a malfunction introduced into
the supplemental restraints system (SRS) during
the diagnostic procedure. It is extremely unlikely
that a malfunctioning SDM would cause a new
malfunction to occur during the diagnostic process.
4. See the caution below.

9T2-2 IMMOBILIZER SYSTEM
DESCRIPTION AND OPERATION
Immobilizer is a device disabling vehicle ignition unless
a speific key is used and designed to help prevent
vehicle theft.
Immobilizer is comprised of two devices, a key with
encoded transponder and engine control unit (ECU)
with the same encoding of the transponder. When a
key is inserted into the key hole to start vehicle and
turned to ‘ON’, the ECU reads and decodes the
transponder code and, if the same, starts the engine,
it is called immobilizer. It means immobilizer system
disables starting by stopping fuel supply if the code
in the transponder does not match the code stored in
ECU each other.
Notice:
If vehicle is equipped with immobilizer system and
the engine cranks normally but not start, check
immobilizer system first rather than ignition and
other electrical systems because it can be
disabled fuel supply of injectors by ECU due to
defective immobilizer system.
Programming of the immobilizer system will be
performed by authorized personnel only. If
following defective codes for immobilizer system
appear during diagnosis of vehicle with SCANNER,
ask immobilizer programming to authorized
personnel and actual programming should be
performed by authorized per-sonnel only.
Display of defectives relevant to immobilizer
system : SCANNER
1. No communication with transponder
2. No immobilizer programming
The transponder in the key can be damaged by
shocks of dropping or hitting other objectives, so
handle it with care.
Each supplied key has programming of code on
its own. Accordingly if ECU needs to be replaced,
replace the transponder in the key.
The vehicle equipped with immobilizer system will
never be started with remote ignition device, so
do not attempt to install it.
The immobilizer system will never be removed from
the vehicle. So never attempt to remove it to install
a remote ignition device or others.
If engine does not start during service, use every
key to start the engine and then check immobilizer
sys-tem finally.
Cases that requires immobilizer
programming
1. Replacement ECU
In this case, replace the every transponder of the
key at once.
2. Replacement of the transponder
3. Additional key for lost 1 or 2 keys
1) Clear all codes for current keys from the ECU
2) When using current key : clear code of the trans-
ponder and re-program it
3) Additional (purchased) key : perform programming
4. When lost all keys
1) Clear all memorized key codes from the ECU
2) Replace the key and key set
3) Immobilizer programming
