FI SYSTEM DIAGNOSIS 12-9
• Disconnect the connector/coupler included in circuit (coupler
B
) and measure resistance between terminal
A
and body
ground.
If continuity is indicated, the circuit is shorted to the ground
between terminals
A
and
B
.

USING THE MULTI CIRCUIT TESTER
• Use the Suzuki multi circuit tester set (09900-25008).
• Use well-charged batteries in the tester.
• Be sure to set the tester to the correct testing range.
USING THE TESTER
• Incorrectly connecting the
+
and
-
probes may cause the
inside of the tester to burnout.
• If the voltage and current are not known, make measure-
ments using the highest range.
• When measuring the resistance with the multi circuit tester
1
,
∞
will be shown as 10.00 M
Ω
and “1” flashes in the display.
• Check that no voltage is applied before making the measure-
ment. If voltage is applied the tester may be damaged.
• After using the tester, turn the power off.

NOTE:
* When connecting the multi circuit tester, use the needle-point
probe to the back side of the lead wire coupler and connect
the probes of tester to them.
* Use the needle-point probe to prevent the rubber of the water
proof coupler from damage.
* When using the multi circuit tester, do not strongly touch the
terminal of the ECM coupler with a needle-point tester probe to
prevent the terminal damage or terminal bend.
