FI SYSTEM DIAGNOSIS 5-57
Step 2
1) Connect the TO sensor coupler and ECM coupler.
2) Insert the needle pointed probes to the lead wire coupler.
3) Turn the ignition switch ON.
4) Measure the voltage at the wire side coupler between Black
and B/Br wires.
$ TO sensor voltage (Normal): 0.4 – 1.4 V
(+ Black – - B/Br)
Also, measure the voltage when leaning the motorcycle.
5) Dismount the TO sensor from its bracket and measure the
voltage when it is leaned 65° and more, left and right, from
the horizontal level.
$ TO sensor voltage (Leaning): 3.7 – 4.4 V
(+ Black – - B/Br)
! 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
& Tester knob indication: Voltage (')
Is the voltage OK?
6) After repairing the trouble, clear the DTC using SDS tool.

YES
• Red, Black or B/Br wire open or shorted to
ground, or poor A, L or S connection
• If wire and connection are OK, intermittent trou-
ble or faulty ECM.
• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
NO
• Loose or poor contacts on the ECM coupler
• Open or short circuit
• Replace the TO sensor with a new one.
