D When connecting connectors, also hold connectors and
put them together until they lock securely (a click is heard).
D Be careful not to touch the electrical terminals of parts
which use microcomputers (e.g. electronic control unit like
as ECM, TCM, ABS control module, SDM etc). The static
electricity from your body can damage these parts.
D Never connect any tester (voltmeter, ohmmeter, or whatev-
er) to electronic control unit when its coupler is discon-
nected. Attempt to do it may cause damage to it.
D Never connect an ohmmeter to electronic control unit with
its coupler connected to it. Attempt to do it may cause dam-
age to electronic control unit and sensors.
D Be sure to use a specified voltmeter/ohmmeter. Otherwise,
accurate measurements may not be obtained or personal
injury may result. If not specified, use a voltmeter with high-
impedance (M W/V minimum) or a digital type voltmeter.
D When taking measurements at electrical connectors using
a tester probe, be sure to insert the probe from the wire har-
ness side (backside) of the connector.
