SERVICE INFORMATION FOR ELECTRICAL INCIDENT
HOW TO PROBE CONNECTORS
 Connector damage and an intermittent connection can result from improperly probing of the connector dur-
ing circuit checks.
 The probe of a digital multimeter (DMM) may not corre ctly fit the connector cavity. To correctly probe the
connector, follow the procedures below using a “T” pin. For the best contact grasp the “T” pin using an alliga-
tor clip.
Probing from Harness Side
Standard type (not waterproof type) connector should be probed
from harness side with “T” pin.
 If the connector has a rear cover such as a ECM connector,
remove the rear cover before probing the terminal.
 Do not probe waterproof connector from harness side. Damage to the seal between wire and connector may result.
Probing from Terminal Side
FEMALE TERMINAL
 There is a small notch above each female terminal. Probe each
terminal with the “T” pin through the notch.
Do not insert any object other than the same type male terminal
into female terminal.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
4. While moving the connector, check whether the male terminalcan be easily inserted or not.
 If the male terminal can be easily inserted into the female ter-minal, replace the female terminal.
Waterproof Connector Inspection
If water enters the connector, it can short interior circuits. This may lead to intermittent problems.
Check the following items to maintain the original waterproof characteristics.
RUBBER SEAL INSPECTION Most waterproof connectors are provided with a rubber seal between the male and female connectors. If the seal is missing,
the waterproof performance may not meet specifications.
 The rubber seal may come off when connectors are disconnected.
Whenever connectors are reconnected, check the rubber seal is
properly installed on either side of male or female connector.
WIRE SEAL INSPECTION The wire seal must be installed on the wire insertion area of awaterproof connector. Be sure that the seal is installed properly.
Terminal Lock Inspection
Check for unlocked terminals by pulling wire at the end of connector.
An unlocked terminal may create intermittent signals in the circuit.
Intermittent IncidentINFOID:0000000006280854
DESCRIPTION
Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the
conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The fol-

< SYMPTOM DIAGNOSIS >
SQUEAK AND RATTLE TROUBLE DIAGNOSES
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulatingthe item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area c an often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knockingnoise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicatingthe conditions can isolate most of these
incidents. Repairs usually consistof insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the pos ition the seatis in and the load placed on the seat when
the noise is present. These conditionsshould be duplic ated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspectedcomponents while duplicating the condi-
tions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
orapplying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or onthe engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the \
vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.
