Precautions: 00-2
• Use a torque wrench to tighten fasteners
to the specified torque. Wipe off grease
and oil if a thread is smeared with them.
• After reassembling, check parts for
tightness and proper operation.
• To protect the environment, do not
unlawfully dispose of used motor oil,
engine coolant and other fluids: batteries,
and tires.
• To protect Earth’s natural resources,
properly dispose of used motorcycle and
parts.
Precautions for Electrical Circuit Service
B944H10000003
When handling the electrical parts or servicing the FI
system, observe the following points for the safety of the
system.
Electrical Parts
Connector / Coupler
• Faulty Fl system is often related to poor electrical
contact of connector/coupler. Before servicing
individual electronic part, check electrical contact of
the 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 disconnecting, and push it in fully to engage the
lock when connecting.
• 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.
• Push in the coupler straightly. An angled or skewed
insertion may cause the terminal to be deformed,
possibly resulting in poor electrical contact.
• Inspect each terminal for corrosion and
contamination. The terminals must be clean and free
of any foreign material which could impede proper
terminal contact.
• Before refitting the sealed coupler, make sure its seal
rubber is positioned properly. The seal rubber may
possibly come off the position during disconnecting
work and if the coupler is refitted with the seal rubber
improperly positioned, it may result in poor water
sealing.
• 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 (rear) of the connector/coupler.
• When connecting meter probe from the terminal side
of the coupler (where 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 terminal. Never push in the
probe where male terminal is supposed to fit.
