Initial Inspection

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 (20 °C, 68 °F), unless there is any notice.

NOTE: The measured resistance in except for ambient temperature (20 °C, 68 °F) is reference value.
