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.

• Some connectors do not have a notch above each terminal. To

probe each terminal, remove the connector retainer to make con-
tact space for probing.

MALE TERMINAL

• Carefully probe the contact surface of each terminal using a “T”

pin.

CAUTION:

Never bend terminal.

How to Check Enlarged Contact Spring of Terminal

• An enlarged contact spring of a terminal may create intermittent signals in the circuit.
• If the intermittent open circuit occurs, follow the procedure below to inspect for open wires and enlarged con-

tact spring of female terminal.

1.

Assemble a male terminal and approx. 10 cm (3.9 in) of wire.
NOTE:
Use a male terminal which matches the female terminal.

2.

Disconnect the suspected faulty connector and hold it terminal
side up.

3.

While holding the wire of the male terminal, try to insert the male
terminal into the female terminal.

CAUTION:

Never force the male terminal into the female terminal with
your hands.

4.

While moving the connector, check whether the male terminal
can 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 a

waterproof 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 Incident

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-
