0A-12 GENERAL INFORMATION
• Never connect any tester (voltmeter, ohmmeter, or what-
ever) to electronic control unit when its coupler is dis-
connected. 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 damage to electronic control unit and sensors.
• Be sure to use a specified voltmeter / ohmmeter. Other-
wise, accurate measurements may not be obtained or
personal injury may result.
• 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
coupler (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 male terminal is supposed
to fit.
• When checking connection of terminals, check its male
half for bend and female half for excessive opening and
both for locking (looseness), corrosion, dust, etc.
• Before measuring voltage to check for electrical system,
check to make sure that battery voltage is 11V or higher.
Such terminal voltage check at low battery voltage will
lead to erroneous diagnosis.
