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 Points00-13
INSPECTION SERVICE POINTS FOR A BLOWN
FUSE
Remove the blown fuse and measure the resistance between
the load side of the blown fuse and the earth. Set the switches
of all circuits which are connected to this fuse to a condition
of continuity. If the resistance is almost 0Ωat this time,
there is a short somewhere between these switches and the
load. If the resistance is not 0Ω, there is no short at the
present time, but a momentary short has probably caused
the fuse to blow.
The main causes of a short circuit are the following.
DHarness being clamped by the vehicle body
DDamage to the outer casing of the harness due to wear
or heat
DWater getting into the connector or circuitry
DHuman error (mistakenly shorting a circuit, etc.)
POINTS TO NOTE FOR INTERMITTENT
MALFUNCTIONS
Intermittent malfunctions often occur under certain conditions,
and if these conditions can be ascertained, determining the
cause becomes simple. In order to ascertain the conditions
under which an intermittent malfunction occurs, first ask the
customer for details about the driving conditions, weather
conditions, frequency of occurrence and trouble symptoms,
and then try to recreate the trouble symptoms. Next, ascertain
whether the reason why the trouble symptom occurred under
these conditions is due to vibration, temperature or some
other factor. If vibration is thought to be the cause, carry
out the following checks with the connectors and components
to confirm whether the trouble symptom occurs.
The objects to be checked are connectors and components
which are indicated by inspection procedures or given as
probable causes (which generates diagnosis codes or trouble
symptoms.)
DGently shake the connector up, down and to the left and
right.
DGently shake the wiring harness up, down and to the
left and right. Check the branch point of wiring harness
connector closely.
DGently rock each sensor and relay, etc. by hand.
DGently shake the wiring harness at suspensions and other
moving parts.
NOTE
If determining the cause is difficult, the flight recorder function
of the MUT-IIcan also be used.

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.

6. Inspection of the SRS-ECU harness connector should be carried out by the following procedure.
Insert the special tool (probe, MB991222, in the harness set) into the connector from harness side
(rear side), and connect the tester to this probe. If any tool than specified is used, damage to the
harness and other components will result. Furthermore, measurement should not be carried out by
touching the probe directly against the terminals from the front of the connector. The terminals are
plated to increase their conductivity, so that if they are touched directly by the probe, the plating
may break, which will cause drops in reliability.

7. SRS components and seat belt with pre-tensioner should not be subjected to hart, so remove the
SRS-ECU, driver’s and front passenger’s air bag modules, clock spring, and seat belt with pre-tensioner
before drying or baking the vehicle after painting.

or more
DSeat belt with pre-tensioner : 90Æ
or more
8. Whenever you finish servicing the SRS, check warning lamp operation to make sure that the system
functions properly. (Refer to P.52B-6.)
9. Make certain that the ignition switch is LOCK (OFF) position when the MUT-IIis connected or
disconnected.
10. If you have any questions about the SRS, please contact your local distributor.
