CONNECTOR MEASUREMENT SERVICE POINTS
Turn the ignition switch to OFF when connecting disconnecting
the connectors, and turn the ignition switch to ON when
measuring if there are no instructions to be contrary.
IF INSPECTING WITH THE CONNECTOR CONNECTED
(WITH CIRCUIT IN A CONDITION OF CONTINUITY)
Waterproof Connectors
Be sure to use the special tool (harness connector). Never
insert a test bar from the harness side, because to do so
will reduce t h e waterproof performance and result in corrosion.
Ordinary (non-waterproof) Connectors
Check by inserting th e test bar from the harness side. Note
that if the connector (control unit, etc.) is too small to permit
insertion of the test bar, it should not be forced; use a special
tool (the extra-thin probe in the harness set for checking
for this purpose.
IF INSPECTING WITH THE CONNECTOR DISCONNECTED
<When Inspecting a Female Pin>
Use the special tool (inspection harness for connector pin
contact pressure in the harness set for inspection).
The inspection harness for connector pin contact pressure
should be used. the test bar should never be forcibly inserted,
as it may cause a defective contact.
<When Inspecting a Male Pin>
Touch the pin directly with the test bar.
Caution
At this time, be careful not to short the connector pins
with the test bars. To do so may damage the circuits
inside the ECU.
