Dealer Troubleshooting

When the grip heater has abnormalities, the grip heater status icon on the combination meter and the grip heater switch indicator show following displays. Follow each instruction to perform inspection.

Inspection Steps:

• 1. Battery Inspection: Refer to the Service Manual and inspect the battery.
• 2. Connections Check: Check whether wires and cables (terminals and connectors) are connected securely.
• 3. Grip Heater Inspection: Check for resistance between the terminals. Standard: Right: 1.9 ohms +/- 10%, Left: 1.9 ohms +/- 10%.
• 4. Heater Harness Inspection: Check for continuity.
• 5. Heater Replacement: If no abnormality is found after checks 2, 3, and 4, but the grip heater still does not operate properly, replace the grip heater with a new one. Note: It is hard to check the switch with ordinary inspection methods (for continuity, voltage, etc.) because it contains an integrated circuit.
• 6. Circuit of Status Icon Inspection: Refer to the Service Manual and inspect the circuit of status icon.
