FI SYSTEM DIAGNOSIS 4-5
ECM/VARIOUS SENSORS
• Since each component is a high-precision part, great care
should be taken not to apply any severe impacts during
removal and installation.
• Be careful not to touch the electrical terminals of the elec-
tronic parts (ECM, etc.). The static electricity from your body
may damage them.
• When disconnecting and connecting the coupler, make sure
to turn OFF the ignition switch, or electronic parts may get
damaged.
BATTERY
• 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 electronic unit which may
result in serious damage.
