Dealer Troubleshooting
If the grip heater exhibits abnormalities, the grip heater status icon on the combination meter and the heated grip switch indicator will show specific displays. Follow the instructions below for inspection.
Heated Grip Switch Indicator Displays:
- Blink once: Check item 1.
- Blinks twice: Check items 2, 3, 4, 5.
- Blinks 3 times: Check items 2, 3, 4, 5.
- Indicator does not light on: Check items 1, 2, 3, 4, 5.
Inspection Steps:
- Battery Inspection: Refer to the Service Manual and inspect the battery.
- Wire and Cable Check: Ensure wires and cables (terminals and connectors) are securely connected.
- Heated Grip Inspection: Check resistance between the terminals.
- Standard: Right: 8.2 ohms +/- 10%
- Standard: Left: 8.2 ohms +/- 10%
- Heater Harness Inspection: Check for continuity.
- Component Replacement: If no abnormality is found after checks 2, 3, and 4, but the heated grip still does not operate properly, replace the heated grip with a new one.
Note: Checking the switch with ordinary methods (continuity, voltage) is difficult due to its integrated circuit.
