HARNESS CONNECTOR INSPECTION
M1001003900171
CONNECTOR CONTINUITY AND VOLTAGE TEST
Required Special Tools:
• MB991219: Test Harness Set
• MD998459: Test Harness
Follow the steps below to avoid causing poor connector contact
and/or reduced waterproof performance of connectors when
checking continuity and/or voltage at terminals of waterproof
connectors.
CAUTION
Never backprobe a waterproof connector. Backprobing
this type of a connector may cause the terminals to cor-
rode, deteriorating circuit performance.
1. If the circuit is to be checked in the closed state, use a
special tool such as 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, use an appropriate male terminal
for checking the contact pressure of connector pins (such as
MB991219).
CAUTION
Do not contact more than one terminal with the probe at
the same time. 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, 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
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 connec-
tor terminal used for MFI and INVECS-II A/T control circuits 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 the 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.
