DETECTED CONDITION | POSSIBLE CAUSE |
The sensor voltage should be the following for 2 sec. and more after ignition switch turns ON. 0.2 V ≤ Sensor voltage ≤ 4.6 V | • TO sensor circuit open or short. • TO sensor malfunction. • ECM malfunction. |
Inspection
Step 1
1 ) Remove the seat. (7-4)
2) Turn the ignition switch OFF.
3) Check the TO sensor coupler for loose or poor contacts. If OK, then measure the TO sensor resistance.

4) Remove the TO sensor.
5) Measure the resistance between (A) and (B) terminals.
- TO sensor resistance: 19.1 - 19.7 kΩ (A - B terminals)
- 09900-25008: Multi circuit tester set
- Tester knob indication: Resistance (Ω)

Is the resistance OK?
YES | Go to Step 2 |
NO | Replace the TO sensor with a new one. |
Step 2
1) Connect the TO sensor coupler.
2) Insert the needle pointed probe to the lead wire coupler.
3) Turn the ignition switch ON.
4) Measure the voltage at the wire side coupler between Br/W and B/Br wires of the TO sensor at horizontal.
- TO sensor voltage: 0.4 - 1.4 V ((+) Br/W - (-) B/Br)
Also, measure the voltage when leaning of the motorcycle.

5) Measure the voltage when it is leaned more than 65°, left and right, from the horizontal level.
- TO sensor voltage: 3.7 - 4.4 V ((+) Br/W - (-) B/Br)
- 09900-25008: Multi circuit tester set
- 09900-25009: Needle pointed probe set
- Tester knob indication: Voltage (⎓)
![](https://motoinstruction.ru/img/suzuki/14/120289.jpg)
Is the voltage OK?
YES | • Red, Br/W or B/Br wire open or shorted to ground, or poor (10), (41) or (34) connection. • If wire and connection are OK, intermittent trouble or faulty ECM. • Recheck each terminal and wire harness for open circuit and poor connection. |
NO | • Loose or poor contacts on the ECM coupler. • Open or short circuit in the Br/W wire or B/Br wire. • Replace the TO sensor with a new one. |
