CONNECTOR ENGAGEMENT INSPECTION
Required Special Tool:
• MB991219: Inspection Harness (contained in MB991223
Test Harness)
Use special tool, MB991219, to inspect the engagement of the
male pins and female pins. [Pin drawing force: 1 N (0.2 pound)
or more]
HOW TO COPE WITH INTERMITTENT
MALFUNCTIONS
Most intermittent malfunctions occur under certain
conditions. If those conditions can be identified, the
cause will be easier to find.
.
TO COPE WITH INTERMITTENT MALFUNCTION;
1. Ask the customer about the malfunction
• Ask what it feels like, what it sounds like, etc.
Then ask about driving conditions, weather, fre-
quency of occurrence, and so on.
2. Determine the conditions from the customer's
responses
• Typically, almost all intermittent malfunctions
occur from conditions like vibration, temperature
and/or moisture change, poor connections. From
the customer's responses, it should be reasoned
which condition is influenced.
3. Use simulation test
• In the cases of vibration or poor connections, use
the simulation tests below to attempt to duplicate
the customer's complaint. Determine the most
likely circuit(s) and perform the simulation tests
on the connectors and parts of that circuit(s). Be
sure to use the inspection procedures provided
for diagnostic trouble codes and trouble symp-
toms.
• For temperature and/or moisture conditions
related intermittent malfunctions try to change the
conditions of the suspected circuit components,
then use the simulation tests below.
4. Verify the intermittent malfunction is elimi-
nated
• Repair the malfunctioning part and try to dupli-
cate the condition(s) again to verify the intermit-
tent 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 scan tool 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
.
• Vibrate the part or sensor.

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 ground. Set the
switches of all circuits which are connected to this fuse to a
condition of continuity. If the resistance is almost 0
Ω at this
time, there is a short somewhere between these switches and
the load. If the resistance is not 0
Ω, 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.)

VEHICLE IDENTIFICATION CODE CHART PLATE
All vehicle identification numbers contain 17 digits. The vehicle
number is a code which tells country, make, vehicle type, etc.
NOTE: *: Check digit means a single number or letter X used to
verify the accuracy of transcription of vehicle identification num-
ber.
