PRECAUTIONS FOR ELECTRICAL CIRCUIT
SERVICE
When disconnecting and connecting coupler, make sure to
turn ignition switch OFF, or electronic parts may get dam-
aged.
Be careful not to touch the electrical terminals of parts
which use microcomputers (e.g. electronic control unit like
as ECM, PCM, P/S controller, etc.). The static electricity
from your body can damage these parts.
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.
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.
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
/V minimum) or a digital type voltmeter.
When taking measurements at electrical connectors using
a tester probe (2), be sure to insert the probe from the wire
harness side (backside) of the connector (1).
When connecting meter probe (2) from terminal side of cou-
pler (1) because it can’t be connected from harness side,
use extra care not to bend male terminal of coupler of force
its female terminal open for connection.
In case of such coupler as shown connect probe as shown
to avoid opening female terminal.
Never connect probe where (3) male terminal is supposed
to fit.
