Follow the steps below to avoid causing poor connector contact
and/or reduced waterproof performance of connectors when
checking continuity and/or voltage at connectors of waterproof
connectors.

CAUTION

Never backprobing a waterproof connector. Backprobing a
connector may cause the terminals to corrode,
deteriorating circuit performance.
1. If checking is performed with the circuit in the state of

continuity, to use special tool MD998459.

CAUTION

Forcing the probe into the terminal may open the terminal,
causing intermittent or poor contact and creating an open
circuit.
2. If the connector is disconnected for checking and the facing

part is the female pin side, the harness for checking the
contact pressure of connector pins (MB991219) should be
used.

CAUTION

Do not simultaneously contact more than one terminal
with the probe. Contacting two or more terminals at the
same time may damage a circuit, possibly to the point of
starting an electrical fire.
3. If the facing part is the male pin side, contact the test probe

directly at the pins.

IMPROPER TERMINAL ENGAGEMENT CHECK

Terminals inside a connector may not engage properly even if
the connectors engage. Make sure that each terminal does not
come out of the connector when gently pulling each harness
wire. If it does, repair or replace the connector.

CONNECTOR TERMINAL ENGAGEMENT AND
DISENGAGEMENT

Loosely engaged terminals can be repaired by removing the
female terminal from the connector housing and raising its
lance to establish better engagement. Removal of the
connector terminal used for MFI and INVECS-II A/T control
circuit can be done in the following manner.
COMPUTER CONNECTOR
1. Insert a screwdriver [1.4 mm (0.06 inch) width] as shown in

the figure, disengage front holder, and remove it.

2. Push the harness wire of the terminal to be repaired deep

into the connector from the harness side and hold it there.

3. Insert the tip of the screwdriver [1.4 mm (0.06 inch) width]

into the connector as shown in the figure, raise the housing
lance slightly with the tip, and pull out the terminal.

4. Insert a needle through the hole provided on the terminal

and raise the contact point. Lightly squeeze the outer edge
so the flats are parallel with the bottom.

ROUND WATERPROOF CONNECTOR
1. Remove the waterproof cap by using a screwdriver.

2. Insert the tip of the screwdriver [1.4 mm (0.06 inch) or 2.0

mm (0.08 inch) width] into the connector as shown in the
figure, raise the housing lance slightly with the tip, and pull
out the terminal.

3. Insert a screwdriver through the hole provided on the

terminal and raise the contact point. Lightly squeeze the
outer edge so the flats are parallel with the bottom.

RECTANGULAR WATERPROOF CONNECTOR
1. Disengage the front holder with a screwdriver and remove it.

2. Insert the tip of a screwdriver [0.8 mm (0.03 inch) width] into

the connector as shown in the figure, push it lightly to raise
the housing lance, and pull out the terminal.

3. Press the contact point of the male terminal down by holding

a screwdriver [1.4 mm (0.06 inch) width] as shown in the
figure. Lightly squeeze the outer edge so the flats are
parallel with the bottom.
