Dealer Troubleshooting

Stop the engine and turn the main switch OFF when you check the parts and circuits other than those of the heated grips.

Symptom Check
Heated grip does not operate;
- Faulty heated grip
- Faulty heated grip coil
- Blown fuse
- Open or short circuit in heater harness
- Faulty heater switch
1. Check whether wires and cables (terminals and connectors) are connected securely.
2. Heated grip inspection: Check for resistance between the terminals.
Standard:
Right: 2.2 ohms +/- 10%
Left: 2.2 ohms +/- 10%
3. Heater harness inspection: Check for continuity by referring to the wiring diagram.
4. If no abnormality is found after the above checks 1, 2, and 3, but the heated grip still does not operate properly, replace the left heated grip/switch with a new one.
- It is hard to check the switch in ordinary inspection method (for continuity etc.) because it contains an IC circuit.
