Electronic Circuit Inspection Procedure
ELECTRONIC CIRCUIT INSPECTION PROCEDURE
1. BASIC INSPECTION
a. RESISTANCE MEASURING CONDITION OF ELECTRONIC PARTS
1. Unless stated, all resistance is measured at an ambient temperature of 20° C (680° F). Because the resistance may be outside the
specifications if measured at high temperatures immediately after the vehicle has been running, measurements should be made when the
engine has cooled down.
b. HANDLING OF CONNECTOR
1. When removing the connector with a lock, press the connector toward the engagement and remove the lock by making the lock claw
movable easily.
2. When removing the connector, do not hold the harness, but hold the connector.
3. Before connecting the connector, check that there are no deformation, damage and missing of the terminals.
4. Connection of the connector with a lock should be securely done until it makes a click sound.
5. In case of checking the connector with a Toyota electrical tester, perform it at the back side (harness side) of the connector using a mini test
lead.
