Suzuki TU250X User Manual

FI SYSTEM DIAGNOSIS 4-5
• Be careful not to touch the electrical terminals of the ECM.
The static electricity from your body may damage this part.
• When disconnecting and connecting the ECM, make sure to
turn OFF the ignition switch 1, 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 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 with a low voltage battery will lead to erroneous diagno-
sis.
