4. VERIFY THE INTERMITTENT MALFUNCTION IS
ELIMINATED
Repair the malfunctioning part and try to duplicate the condi-
tion(s) again to verify the intermittent malfunction has been
eliminated.
.
SIMULATION TESTS
NOTE: In case of difficulty in finding the cause of the intermit-
tent malfunction, the data recorder function in the
DIAGNOSTIC TOOL (MUT-III) is effective.
For these simulation tests, shake, then gently bend, pull, and
twist the wiring of each of these examples to duplicate the inter-
mittent malfunction.
Shake the connector up-and-down, and right-and-left.
Shake the wiring harness up-and-down, and right-and-left.
Especially, check the splice points of wiring harnesses care-
fully. Refer to GROUP 00E, Harness Connector Inspection
P.00E-2.

INSPECTION SERVICE POINTS FOR A BLOWN
FUSE
M1001013800067
Remove the blown fuse and measure the resistance between
the load side of the blown fuse and the ground. Close the
switches of all circuits which are connected to this fuse. If the
resistance is almost 0
at this time, there is a short some-
where between these switches and the load. If the resistance is
not 0
, 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.
Harness being clamped by the vehicle body
Damage to the outer casing of the harness due to wear or
heat
Water getting into the connector or circuitry
Human error (mistakenly shorting a circuit, etc).
HOW TO TREAT CURRENT TROUBLEM1001014000020
1. Make a note of the diagnostic trouble code, and erase it.
2. Check the trouble symptom again.
3. Check for diagnostic trouble codes again.
4. If a diagnostic trouble code is set, follow the applicable
Diagnostic Trouble Code Chart.
5. If no diagnostic trouble code is set, refer to "How to Cope
with Intermittent Malfunction P.00-14."
HOW TO TREAT PAST TROUBLEM1001014100050
1. Establish from the customer whether a fuse or connector
has been replaced or disconnected.
2. If yes, erase the diagnostic trouble code, and then check
that no diagnostic code is reset. If no diagnostic trouble
code is reset, the diagnosis is complete.
3. If no, follow the applicable Diagnostic Trouble Code Chart.

PRECAUTIONS BEFORE SERVICE
GENERAL00-24
SERVICING ELECTRICAL SYSTEMM1001011900057
Battery posts, terminals and related accessories con-
tain lead and lead compounds. WASH HANDS AFTER
HANDLING.
1. Note the following before proceeding with working on the
electrical system.
Never perform unauthorized modifications to any electrical
device or wiring. Such modifications might lead to a vehicle
malfunction, over-capacity or short-circuit that could result in
a fire in the vehicle.
Before connecting or disconnecting the negative bat-
tery cable, be sure to turn the ignition switch to the
"LOCK" (OFF) position and turn off the lights (If this is
not done, there is the possibility of semiconductor
parts being damaged).
After completion of the work (and the negative battery
terminals is connected), warm up the engine and allow
it to idle for approximately 10 minutes under the condi-
tions described below in order to stabilize engine con-
trol conditions, and then check to be sure that the idle
is satisfactory.
Engine coolant temperature: 85 to 95C (185 to
203
F)
Lights and all accessories: OFF
Transaxle: "N" or "P" position
Steering wheel: straight-forward position
2. When servicing the electrical system, disconnect the
negative cable terminal from the battery.
VEHICLE WASHINGM1001012000057
If high-pressure car-washing equipment or steam car-washing
equipment is used to wash the vehicle, be sure to maintain the
spray nozzle at a distance of at least approximately 50 cm (20
inches) from any plastic parts and all opening parts (doors, lug-
gage compartment, etc.).

FRONT IMPACT SENSORS
1. Check that the arrows on the sensors face toward the front
of the vehicle.
The SRS may not activate if a front impact sensor
is not installed properly, which could result in seri-
ous injury or death to the vehicle's driver and pas-
senger.
If a dent, crack, deformation or rust is detected,
replace with a new sensor.
2. Check the front side member and front impact sensor for
deformation or rust.
3. Check the front impact sensor wiring harness for binding;
Check the connector for damage; and check the terminals
for deformation.
Replace the sensor and/or wiring harness if they fail the
visual check (Refer to GROUP 52B, SRS Service
Precautions P.52B-16 and GROUP 52B, Front Impact
Sensor P.52B-231).
SIDE IMPACT SENSORS
If the side impact sensor is not installed securely
and correctly, the side-air bag may not operate
normally.
If a dent, crack, deformation or rust is detected,
replace with a new sensor.
1. Check the side impact sensor and bracket for dents, cracks
or deformation. The side impact sensors are located inside
the center pillars (LH/RH).
2. Check the connector for damage, and terminal for
deformation.
3. Check that there is no bending or corrosion in the center
pillars (LH/RH).
Replace the side impact sensor if it fails the visual check
(Refer to GROUP 52B, Side Impact Sensor P.52B-247).
NOTE: The illustration shows the left side impact sensor (RH).
The position of the other side impact sensor (LH) is symmetri-
cal to this.
