PRECAUTIONS IN SERVICING
When handling the FI component parts or servicing the FI sys-
tem, observe the following points for the safety of the system.
CONNECTOR/COUPLER
• When connecting a connector, be sure to push it in until a click
is felt.
• With a lock type coupler, be sure to release the lock when dis-
connecting, and push it in fully till the lock works when con-
necting it.
• When disconnecting the coupler, be sure to hold the coupler
body and do not pull the lead wires.
• Inspect each terminal on the connector/coupler for looseness
or bending.
• Inspect each terminal for corrosion and contamination.
The terminals must be clean and free of any foreign material
which could impede proper terminal contact.
• Inspect each lead wire circuit for poor connection by shaking it
by hand lightly. If any abnormal condition is found, repair or
replace.
• When taking measurements at electrical connectors using a
tester probe, be sure to insert the probe from the wire harness
side (backside) of the connector/coupler.
• When connecting meter probe from the terminal side of the
coupler (connection from harness side not being possible), use
extra care not to force and cause the male terminal to bend or
the female terminal to open.
Connect the probe as shown to avoid opening of female termi-
nal.
Never push in the probe where male terminal is supposed to
fit.
• Check the male connector for bend and female connector for
excessive opening. Also check the coupler for locking (loose-
ness), corrosion, dust, etc.
