4-2 FI SYSTEM DIAGNOSIS
PRECAUTIONS IN SERVICING
When handling the component parts or servicing the FI system,
observe the following points for the safety of the system .
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 works when connecting
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 ter-
minal.
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 .

O/
FUSE
•
When a fuse blows, always investigate the cause 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 .

ECMNARIOUS 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 ECM .
The static electricity from your body may damage this part .

4-4 FI SYSTEM DIAGNOSIS
•
When disconnecting and connecting the ECM, make sure to
turn OFF the ignition switch, or electronic parts may get dam-
aged.
•
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 elec-
tromotive force will be applied to the ECM 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 at low battery voltage will lead to erroneous diagnosis
.
Never connect any tester (voltmeter, ohmmeter, or whatever)
to the ECM when its coupler is disconnected
.
Otherwise, damage to ECM may result .
•
Never connect an ohmmeter to the ECM with its coupler con-
nected. If attempted, damage to ECM or sensors may result
.
•
Be sure to use a specified voltmeter/ohmmeter
. Otherwise,
accurate measurements may not be obtained and personal
injury may result .
