Electrical Circuit Inspection Procedure
While there are various electrical circuit inspection methods, described here is a general method to check its open and short circuit by using an ohmmeter
and a voltmeter.
Open Circuit Check
Possible causes for the open circuit are as follows. As the cause is in the connector or terminal in many cases, they need to be checked particularly
carefully.
^
Loose connection of connector
^
Poor contact of terminal (due to dirt, corrosion or rust on it, poor contact tension, entry of foreign object etc.)
^
Wire harness being open
When checking system circuits including an electronic control unit such as ECM, TCM, ABS control module, etc., it is important to perform
careful check, starting with items which are easier to check.
1. Disconnect negative ( ) cable from battery
