How to Use Troubleshooting/Inspection Service ‘Points
CONNECTOR
Turn the ignition switch to when connecting and discon-
necting the connectors, and turn the ignition switch to ON
when measuring if there are no instructions to the contrary.
IF INSPECTING WITH THE CONNECTOR CONNECTED
(WITH CIRCUIT IN A CONDITION OF
Waterproof Connectors
Be sure to use the special tool (harness connector). Never
insert a test probe from the. harness side, because to do
so will reduce the waterproof performance and result in corro-
sion.
Ordinary (non-waterproof) Connectors
Check by inserting the test probe from’. the harness side.
Note that if the connector (control unit, etc.) is too small to
permit insertion of the test probe, 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 pin
contact pressure in the harness set, for ‘inspection).
The inspection harness for connector pin contact pressure’
should be used. The test probe be forcibly in-
serted, as it may cause a defective contact.
<When Inspecting a Male
Touch the pin directly with the test bar.
Caution
. .
At time, be careful not to short the connector
with the test probes. To do so may damage the
inside the ECU.
