Seat Belt with Pretensioner (If so
equipped)
The seat belt comprises a seat belt and a cylinder (a
cylinder filled with powder and an ignition device). In
cases of frontal collision which cause a shock
exceeding a specified level, the controller lets current
flow to the inflation circuit. The current ignites the
cylinder of the seat belt, producing gas. The gas helps
tighten the seat belt to restrain firmly the driver’s uppe
r
half in his seat.
RTW 49JSH000201
Steering Column
The steering column absorbs energy and is designed
to compress in a frontal crash to decrease the chance
of injury to the driver.
060R300038
Knee Bolster
The knee bolsters are used to absorb energy to
protect knees and control the forward movement o
f
the vehicle's front seat occupants during a frontal
crash, by limiting leg movement.
Definitions
Air Bag
An inflatable cloth cushion designed to deploy in
certain frontal crashes. It supplements the protection
offered by the seat belts by distributing the impact load
more evenly over the vehicle occupant's head and
torso.

maintain sufficient voltage to cause a deployment fo
r
up to 15 seconds after the ignition switch is turned
“OFF,” the battery is disconnected, or the fuse
powering the SRS control unit is removed.
Many of the service procedures require removal of the
“SRS” fuse, and disconnection of the air bag assembl
y
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.

°C (150°F).
2. The air bag assembly, and SRS control unit, should not be used if they have been dropped from
a height of 100 centimeters (3.28 feet) or more.
3. W hen the SRS control unit 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 SRS control unit to be located flat on the
mounting surface, parallel to the vehicle datum
line. It is important that the SRS control unit
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 “SRS”
warning lamp operation and will lead you to the
correct chart to diagnose any SRS malfunctions.

Diagnostic Information and Procedures
Diagnostic Starting Point - Immobilizer
Controls
Begin the system diagnosis with Diagnostic System
Check - Immobilizer Controls. The Diagnostic System
Check - Immobilizer Controls will provide the following
information:
• The identification of the control modules which command the system.
• The ability of the control modules to communicate through the serial data circuit.
• The identification of any stored diagnostic trouble codes (DTCs) and the their statuses.
The use of the Diagnostic System Check - Immobilizer
Controls will identify the correct procedure for
diagnosing the system and where the procedure is
located.
Diagnostic System Check - Immobilizer
Controls
Description
The Diagnostic System Check - Immobilizer Controls is
an organized approach to identifying a condition that is
created by a malfunction in the electronic immobilizer
control system. The Diagnostic System Check must be
the starting point for any immobilizer system concern.
The Diagnostic System Check directs the service
technician to the next logical step in order to diagnose
the concern. Understanding and correctly using the
diagnostic table reduces diagnostic time, and prevents
the replacement of good parts. Test Description
The numbers below refer to the step numbers on the
diagnostic table.
2. Lack of communication may be because of a partial
or a total malfunction of the serial data circuit.
6. The presence of DTCs which begin with U, indicate
that some other module is not communicating.
9. If there are other modules with DTCs set, refer to the
DTC list. The DTC list directs you to the appropriate
diagnostic procedure.
Important: • DO NOT perform this diagnostic if there is not an immobilizer system concern, unless another
procedure directs you to this diagnostic.
• Before you proceed with diagnosis, search for applicable service bulletins.
• Unless a diagnostic procedure instructs you, DO NOT clear the DTCs.
• Ensure the battery has a full charge.
• Ensure the battery cables (+) (-) are clean and tight.
• Ensure the ICU ground is clean, tight, and in the correct location.
• Ensure the ICU harness connector is clean and correctly connected.
• Ensure the ICU terminals are clean and correctly mating.
• Ensure the immobilizer security information is correctly programmed into the ICU, ECM and PIM.
• Ensure the ICU is correctly installed to the steering lock.
• Ensure objects does not block transponder key in the steering lock.
• Ensure another transponder key is not attached to the key ring.
