Connector Measurement Service Points
CONNECTOR MEASUREMENT SERVICE POINTSTurn the ignition switch to OFF when connecting and disconnecting 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 CONTINUITY)
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 corrosion.
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 connector pin contact pressure in the harness set for inspection). The inspection harness for connector pin contact pressure should be used. The test probe 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 probes. To do so may damage the circuits inside the ECU.
