CONNECTOR INSPECTION SERVICE
POINTS

VISUAL INSPECTION
•
AC300896AB
Connector disconnected or
improperly connected
Stretched or broken wires
Low contact
pressure
Harness wire breakage
at terminal section
Good
Bad
Connector is disconnected or improperly connected
• Connector pins are pulled out
• Due to harness tension at terminal section
• Low contact pressure between male and female
terminals
• Low connection pressure due to rusted terminals
or foreign matter lodged in terminals
CONNECTOR PIN INSPECTION
AC300898
If the connector pin stopper is damaged, the terminal
connections (male and female pins) will not be per-
fect even if the connector body is connected, and the
pins may pull out of the reverse side of the connec-
tor. Therefore, gently pull the harnesses one by one
to make sure that no pins pull out of the connector.
CONNECTOR ENGAGEMENT INSPECTION
AC300899AB
MB991219
Use special tool inspection harness (MB991219)
(connector pin connection pressure inspection har-
ness of the inspection harness set) to inspect the
engagement of the male pins and female pins. (Pin
drawing force: 1 N or more)

occurrence
section
Remove the blown fuse and measure the resistance
between the load side of the blown fuse and the
earth. 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 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.)
HOW TO COPE WITH INTERMITTENT
MALFUNCTIONS
M1001013900406
AC300901
Intermittent malfunctions often occur under certain
conditions, and if these conditions can be ascer-
tained, determining the cause becomes simple. In
order to ascertain the conditions under which an
intermittent malfunction occurs, first ask the cus-
tomer for details about the driving conditions,
weather conditions, frequency of occurrence and
trouble symptoms, and then try to recreate the trou-
ble symptoms. Next, ascertain whether the reason
why the trouble symptom occurred under these con-
ditions 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 gen-
erates diagnosis codes or trouble symptoms).

• Gently shake the connector up, down and to the
left and right.
• Gently shake the wiring harness up, down and to
the left and right.
• Gently rock each sensor and relay, etc. by hand.
• Gently shake the wiring harness at suspensions
and other moving parts.
NOTE: If determining the cause is difficult, the drive
recorder function of the M.U.T.-III can also be used.
(For details on how to use the M.U.T.-III, refer to the
"M.U.T.-III operation manual).
HOW TO TREAT PAST TROUBLE
M1001014100403
Since the trouble may still be present even the status
is "Stored", set the vehicle to the diagnosis 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 diagnosis code, and then check
that no diagnostic code is reset. If no diagnosis
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
