| DETECTED CONDITION | POSSIBLE CAUSE |
| No Gear Position switch voltage Switch voltage is not within the following range. Switch voltage > 0.6 V | Gear Position switch circuit open or short Gear Position switch malfunction ECM malfunction |
Inspection
Step 1
- 1) Turn the ignition switch OFF.
- 2) Remove the right frame side cover. (9-5)
- 3) Check the GP switch coupler for loose or poor contacts. If OK, then measure the GP switch voltage.
- 4) Support the motorcycle with a jack.
- 5) Fold the side-stand to up position.
- 6) Make sure the engine stop switch is in the "RUN" position.
- 7) Insert the needle pointed probe to the lead wire coupler.
- 8) Turn the ignition switch ON.
- 9) Measure the voltage at the wire side coupler between Pink wire and B/W wire, when shifting the gearshift lever from 1st to Top.
- GP switch voltage: 0.6 V and more
- (+ Pink - − B/W)
- 09900-25008: Multi-circuit tester set
- 09900-25009: Needle pointed probe set
- Tester knob indication: Voltage
Is the voltage OK?
| YES | Pink wire open or shorted to ground If wire and connection are OK, intermittent trouble 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 | Pink or B/W wire open, or Pink wire shorted to ground Loose or poor contacts on the ECM coupler (terminal 23 or 34) If wire and connection are OK, replace the GP switch with a new one. |
- 10) After repairing the trouble, clear the DTC using SDS tool. (5-26)
