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

M1001013900451

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, frequency of occurrence, and so
on.

.

2. DETERMINE THE CONDITIONS FROM THE
CUSTOMER'S RESPONSES

Typically, almost all intermittent malfunctions occur from condi-
tions like vibration, temperature and/or moisture change, poor
connections. From the customer's responses, it should be rea-
soned which condition is most likely.

.

3. USE SIMULATION TEST

Use the simulation tests below to attempt to duplicate the cus-
tomer's complaint. Determine the most likely circuit(s) and per-
form 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 symptoms.
For temperature and/or moisture condition related intermittent
malfunctions, try to change the conditions of the suspected cir-
cuit components, then use the simulation tests below.

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 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

P.00E-2

.

• Shake the part or sensor.

HOW TO TREAT PAST TROUBLE

M1001014100384

Since the trouble may still be present even the status
is "Stored", set the vehicle to the diagnostic trouble
code detection condition and check that the status
changes to "Active". If the status does not change
from "Stored", carry out the following procedure.
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. Then check the wiring harness and
connector, and refer to "How to Cope with
Intermittent Malfunction

P.00-15

INSPECTION SERVICE POINTS FOR A BLOWN
FUSE

M1001013800409

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

Ω at this time, there is a short some-

where 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.)
