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

ZC6001610000

MD998459

Never backprobe a waterproof connector. Backprobing a
connector may cause the terminals to corrode,
deteriorating circuit performance.

If the circuit to be checked is a closed state, use a special tool
like MD998459.

ZC600162

MB991219

0000

Forcing the probe into the terminal may open the terminal,
causing intermittent or poor contact and creating an open
circuit.

If the connector is disconnected for checking and the facing
part is the female pin side, use an appropriate male terminal
for checking the contact pressure of connector pins (like
MB991219).

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.

If the facing part is the male pin side, either carefully touch the
probe to the pin so it does not accidentally contact other pins,
or use an appropriate female terminal.

IMPROPER TERMINAL ENGAGEMENT CHECK

ZC600163AA00

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 terminal and/or 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.

Front holder

Insert a screwdriver [1.4 mm (0.06 inch) width] as shown in
the figure, disengage the front holder, and remove it.

ZC600165AA00

Push the harness wire of the terminal to be repaired deep into
the connector from the harness side and hold it there.

Insert the tip of the screwdriver [1.4 mm (0.06 inch) width] into
the connector as shown in the figure, gently push the housing
lance down with the tip, and pull out the terminal.

ZC6001670000

Needle

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

ZC6001680000

Housing lance

Remove the waterproof cap by using a screwdriver.

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.

ZC600169AA00

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.
