r
“Continuous Monitoring”. This test checks for the
correct SRS control unit configuration for the vehicle,
shorts to “Ignition 1” in the deployment loops, high

information from on–board computers via the data link
connector.
SRS control unit
SRS control unit which provides reserve energy to the
deployment loops, deploys the air bags when required
and performs diagnostic monitoring of all SRS
components.
Serial Data
Information representing the status of the SRS.

An assembly of two current–carrying coils in the drive
r
deployment loop that allows the rotation of the steering

driver deployment loop to the driver air bag assembly.
SRS Wiring Harness
The wires and connectors that electrically connect the
components in the SRS.
“Turn–ON”
Test which the SRS control unit performs on the SRS
once during each ignition cycle immediately afte
r
“Ignition 1” voltage is applied to the SRS control unit
and before “Continuous Monitoring”.

9A-20 SUPPLEMENTAL RESTRAINT SYSTEM
Repairs And Inspections Required
After An Accident
If any SRS components are damaged, they must be
replaced. If SRS component mounting points are
damaged, they must be replaced.
• Never use SRS parts from another vehicle. This does not include remanufactured parts purchased
from an authorized dealer; they may be used fo
r
SRS repairs.
• Do not attempt to service the SRS control unit, the SRS coil assembly, or the air bag assembly.
Service of these items is by replacement only.
• Verify the part number of the replacement air bag assembly.

CAUTION: Never use the air bag assembly from
another vehicle or different model year air bag
assembly.
Use only a new air bag assembly matched to the
TFR/S which is being repaired.
CAUTION: Proper operation of the sensors and
supplemental restraint system (SRS) requires that
any repairs to the vehicle structure return it to the
original production configuration. Deployment
requires, at a minimum, replacement of the SRS
control unit, air bag assembly and dimensional
inspection of the steering column. Any visible
damage to the SRS control unit mounting bracket
(s) requires replacement, and the steering column
must be dimensionally inspected, whethe
r
deployment occurred or not.
Accident With Deployment – Component
Replacement And Inspections
Certain SRS components must be replaced or
inspected for damage after a frontal crash involving air
bag deployment. Those components are:
• Air bag assembly
• SRS control unit

CAUTION: Refer to “SRS control unit Replacement
Guidelines” below for important information on
SRS control unit replacement in both deployment
and non-deployment crashes.
• SRS coil assembly — Inspect wiring and connecto
r
for any signs of scorching, melting, or damage due
to excessive heat. Replace if damaged. Refer to
section “SRS Coil Assembly” in this manual.

Accident With or Without Deployment –
Component Inspection
Certain SRS system components and rotation parts
must be inspected after any crash, whether the air bag
has been deployed or not. Those components are:
• Steering column — Refer to Inspection Required “After an Accident” in this manual.
• Knee bolsters and mounting points — Inspect fo
r
any distortion, bending, cracking, or other damage.
• I/P steering column reinforcement plate — Inspect for any distortion, bending, cracking, or othe
r
damage.
• I/P braces — Inspect for any distortion, bending, cracking, or other damage.
• Seat belts and mounting points — Refer to “Seat Belts” in Section “Seat Belt” of this workshop
manual.

SRS Control Unit Replacement Guidelines
SRS control unit replacement policy requires
replacement of the SRS control unit after a crash
involving air bag deployment when the “SRS W arning
Lamp” turned “ON”, the “SRS Diagnosis” should be
done according to Section “Restraint Control System.”

Wiring Damage
If any SRS wire harness is damaged, it should be
replaced. Don't repair the SRS harness. It is
replacement only.

SRS Connector (Plastic Body And
Terminal Metal Pin) Damage
If any connector or terminal in the SRS wire harness
(except pigtails) is damaged, it should be replaced.

SRS Wire Pigtail Damage
If the wiring pigtail (a wire or wires attached directly to
the device, not by a connector) is damaged, the entire
component (with pigtail) must be replaced. Examples
of “pigtail” components are the driver air bag
assembly, the passenger air bag assembly, and the
SRS coil assembly.
