Basic Inspection Procedure
Measuring Condition of Electronic Parts' Resistance
The measured resistance at high temperature after vehicle running may be high
or low. So all resistance must
be measured at ambient temperature (20ºC, 68ºF), unless stated otherwise.
Connector Inspection Procedure
Handling of Connector
a. Never pull on the wiring harness when disconnecting connectors.
b. When removing the connector with a lock, press or pull locking lever.
c. Listen for a click when locking connectors. This sound indicates that
