HOW TO USE THE INSPECTION PROCEDURES
The causes of a high frequency of problems occurring in electronic circuitry are generally the connectors,
components, the ECU and the harnesses between connectors, in that order. These inspection procedures
follow this order, and they first try to discover a problem with a connector or a defective component.

dures.

3. Detailed inspection procedures (methods)
such as component inspection and circuit
inspection are listed on a separate page, and
are given here for reference.
5. Inspect the contact condition at each connector terminal.
(Refer to Connector Inspection Service Points.)
The connector position can be located in the wiring diagram in the
electrical wiring manual by means of this symbol.
Caution
After carrying out connector inspection, always be sure to
reconnect the connector as it was before.
6. Confirm that there are trouble symptoms. If trouble symptoms have
disappeared, the connector may have been inserted incorrectly and the
trouble symptom may have disappeared during inspection.
If it seems that trouble symptoms still remain, proceed to the next page of
instructions.
7. If trouble symptoms still remain up to this stage, there is a possibility that there is an
open or short circuit in the harness between the connectors, so check the harness.
Alternatively, the cause may be a defective ECU, so try replacing the ECU and check
if the trouble symptom disappears.

HARNESS INSPECTION
Check for an open or short circuit in the harness between the terminals which were defective according
to the connector measurements. Carry out this inspection while referring to the electrical wiring manual.
Here, “Check harness between power supply and terminal xx” also includes checking for blown fuses.
For inspection service points when there is a blown fuse, refer to “Inspection Service Points for a Blown
Fuse.”
MEASURES TO TAKE AFTER REPLACING THE ECU
If the trouble symptoms have not disappeared even after replacing the ECU, repeat the inspection procedure
from the beginning.

GENERAL -How to Use Troubleshooting/Inspection Service Points00-11
CONNECTOR MEASUREMENT SERVICE POINTS
Turn the ignition switch to OFF when connecting disconnecting
the connectors, and turn the ignition switch to ON when
measuring if there are no instructions to be contrary.
IF INSPECTING WITH THE CONNECTOR CONNECTED
(WITH CIRCUIT IN A CONDITION OF CONTINUITY)
Waterproof Connectors
Be sure to use the special tool (harness connector). Never
insert a test bar from the harness side, because to do so
will reduce the waterproof performance and result in corrosion.
Ordinary (non-waterproof) Connectors
Check by inserting the test bar from the harness side. Note
that if the connector (control unit, etc.) is too small to permit
insertion of the test bar, it should not be forced; use a special
tool (the extra-thin probe in the harness set for checking
for this purpose.
IF INSPECTING WITH THE CONNECTOR DISCONNECTED
Use the special tool (inspection harness for connector pin
contact pressure in the harness set for inspection).
The inspection harness for connector pin contact pressure
should be used. the test bar should never be forcibly inserted,
as it may cause a defective contact.
Touch the pin directly with the test bar.
Caution
At this time, be careful not to short the connector pins
with the test bars. To do so may damage the circuits
inside the ECU.

GENERAL -Precautions Before Service00-18
PRECAUTIONS BEFORE SERVICE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
1. Items to follow when servicing SRS
(1) Be sure to read GROUP 52B - Supplemental Restraint System (SRS).
For safe operations, please follow the directions and heed all warnings.
(2) Wait at least 60 seconds after disconnecting the battery cable before doing any further work.
The SRS system is designed to retain enough voltage to deploy the air bag even after the battery
has been disconnected. Serious injury may result from unintended air bag deployment if work
is done on the SRS system immediately after the battery cable is disconnected.
(3) Warning labels must be heeded when servicing or handling SRS components. Warning labels
are located in the following locations.
DSun visor
DGlove box
DSRS-ECU
DSteering wheel
DSteering Joint Cover
DAir bag module (driver’s side and front passenger’s side)
DClock spring
DSeat belt with pre-tensioner
(4) Always use the designated special tools and test equipment.
(5) Store components removed from the SRS in a clean and dry place.
The air bag module should be stored on a flat surface and placed so that the pad surface is
facing upward.
Do not place anything on top of it.
(6) Never attempt to disassemble or repair the SRS components (SRS-ECU, air bag module, clock
spring and seat belt with pre-tensioner).
(7) Whenever you finish servicing the SRS, check the SRS warning lamp operation to make sure
that the system functions properly.
(8) Be sure to deploy the air bag before disposing of the air bag module or disposing of a vehicle
equipped with an air bag. (Refer to GROUP 52B - Air Bag Module Disposal Procedures.)
2. Observe the following when carrying out operations on places where SRS components are installed,
including operations not directly related to the SRS air bag.
(1) When removing or installing parts do not allow any impact or shock to the SRS components.
(2) SRS components should not be subjected to heat, so remove the SRS components before drying
or baking the vehicle after painting.
DSRS-ECU, air bag module, clock spring: 93_C or more
DSeat belt with pre-tensioner: 90_C or more
After re-installing them, check the SRS warning lamp operation to make sure that the system
functions properly.
Page 399 of 1449
GENERAL -Supplemental Restraint System (SRS)00-21
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
To improve safety, the SRS and seat belts with
pre-tensioner. These systems enhance collision
safety by restraining the front passengers in case
of an accident. The SRS works with the
pre-tensioner simultaneously when a collision is
detected.
The SRS consists of two air bag modules, SRS
air bag control unit (SRS-ECU), SRS warning lamp
and clock spring. The air bags are located in the
center of the steering wheel, above the glove box.
Each air bag has a folded air bag and an inflator
unit. The SRS-ECU under the floor console monitors
the system and has a safing G-sensor and an
analog G-sensor. The warning lamp on theinstrument panel indicates the operational status
of the SRS. The clock spring is installed in the
steering column. The seat belt pre-tensioner is built
into the front seat belt retractor. Only authorized
service personnel should do work on or around
the SRS components and seat belt with
pre-tensioner. Those service personnel should read
this manual carefully before starting any such work.
Extreme care must be used when servicing the
SRS to avoid injury to the service personnel (by
inadvertent deployment of the air bags or
inadvertent operation of the seat belt with
pre-tensioner) or the driver (by rendering the SRS
or the seat belt with pre-tensioner inoperative).

GENERAL -Supplemental Restraint System (SRS)00-22
SRS SERVICE PRECAUTIONS
1. In order to avoid injury to yourself or others
from accidental deployment of the air bag and
accidental operation of the seat belt with
pre-tensioner during servicing, read and
carefully follow all the precautions and
procedures described in this manual.
2. Do not use any electrical test equipment on
or near SRS components, except those
specified on P.52B-6.
3. Never Attempt to Repair the Following
Components:
DSRS air bag control unit (SRS-ECU)
DClock spring
DDriver’s and front passenger’s air bag
modules
DSeat belt with pre-tensionerNOTE
If any of these components are diagnosed as
faulty, they should only be replaced, in
accordance with the INDIVIDUAL COM-
PONENTS SERVICE procedures in this
manual. (Refer to P.52B-49.)
4. After disconnecting the negative (–) battery cable,
wait 60 seconds at least before any service and
insulate the disconnected cable with tape. The SRS
retain enough voltage to deploy the air bags for a
short time even after the disconnection of the battery.
So, serious injury may result by accidental air bag
deployment if a work is done on the SRS just after
the disconnection of the battery.
5. Do not attempt to repair the wiring harness connectors
of the SRS. If the connector(s) are diagnosed as defective,
replace the wiring harness(es). If the harness(es) are
diagnosed as faulty, replace or repair the wiring
harness(es) according to the table that follows.
