4-1. FUEL INJECTION SYSTEM
4-1-3
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 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.
• 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 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.
• Check the male connector for bend and female connector for excessive opening. Also check
the coupler for locking (looseness), corrosion, dust, etc.
FUSE
• When a fuse blows, always investigate the cause to correct it and then replace the fuse.
• Do not use a fuse of a different capacity.
• Do not use wire or any other substitute for the fuse.
ECU/VARIOUS SENSORS
• Since each component is a high-precision part, great care should be taken not to apply any
sharp impacts during removal and installation.
• Be careful not to touch the electrical terminals of the ECU. The static electricity from your
body may damage this part.
• When disconnecting and connecting the ECU couplers, make sure to turn OFF the ignition
switch, or electronic parts may get damaged.
• Battery connection in reverse polarity is strictly prohibited. Such a wrong connection will
damage the components of the FI system instantly when reverse power is applied.
• Removing any battery terminal of a running engine is strictly prohibited. The moment such
removal is made, damaging counter electromotive force will be applied to the ECU, which
may result in serious damage.
• Before measuring voltage at each terminal, check to make sure that battery voltage is 11 V
or higher. Terminal voltage check with a low voltage battery will lead to erroneous diagnosis.
• Never connect any tester (voltmeter, ohmmeter, or whatever) to the ECU when its coupler is
disconnected. Otherwise, damage to the ECU may result.
