Check Engine Lamp

See Controls and Indicators → Instruments → Instruments (Fairing Models, typical) and Controls and Indicators → Instruments → Instruments: FLHR. The check engine lamp indicates the condition of the engine/engine management system.

The check engine lamp normally comes on when the ignition is first turned on and remains on for approximately 4 seconds. During this time, the engine management system runs a series of self-diagnostics.

If the engine lamp comes on at any other time, see a Harley-Davidson dealer.

Low Fuel Lamp

Solid: See Controls and Indicators → Instruments → Instruments (Fairing Models, typical) and Controls and Indicators → Instruments → Instruments: FLHR. The low fuel warning lamp indicates when the gasoline in the tank reaches the low fuel level (approximate). Refer to Specifications → Specifications → Capacities for the low fuel level. See Controls and Indicators → Odometer Functions for fuel range features.

Flashing: If the low fuel lamp flashes continuously or remains on after filling the fuel tank, see a Harley-Davidson dealer.

Battery Discharge Lamp

See Controls and Indicators → Instruments → Instruments (Fairing Models, typical) and Controls and Indicators → Instruments → Instruments: FLHR. The battery discharge lamp indicates overcharging or undercharging of the battery. Refer to Maintenance and Lubrication → Battery Maintenance.

Electrical System Lamp

See Controls and Indicators → Instruments → Instruments (Fairing Models, typical) and Controls and Indicators → Instruments → Instruments: FLHR. The electrical system lamp displays the status of the security system and electrical self-diagnostics for the motorcycle. Refer to SECURITY SYSTEM → Security System for security system operation.

Flashing: The security system is armed.

Solid (security system armed): The alarm has been activated.

Solid (security system disarmed): If the lamp remains on, see a Harley-Davidson dealer.

Turn Signal Indicator Lamps

Flashing: A turn signal is activated. When the 4-way hazard flashers are operating, both turn indicators flash simultaneously.

Rapid flashing: A turn signal bulb is not operating. Exercise caution and use hand signals. Replace inoperative components at earliest opportunity.

Headlamp High Beam Lamp

See Controls and Indicators → Instruments → Instruments (Fairing Models, typical) and Controls and Indicators → Instruments → Instruments: FLHR. The headlamp high beam lamp is on when the high beam or flash to pass switch is activated.

Neutral Lamp

See Controls and Indicators → Instruments → Instruments (Fairing Models, typical) and Controls and Indicators → Instruments → Instruments: FLHR. The neutral lamp is on when the transmission is in neutral.

Cruise Control Lamp

Off: Cruise control is not enabled.

Orange: Cruise control is enabled. Cruising speed is not set or has been disengaged.

Green: Cruising speed is set. Vehicle speed is being maintained by the cruise control system.

Auxiliary/Fog Lamp Indicator Lamp

The auxiliary/fog lamp indicator is on when the auxiliary/fog lamps are turned on (for equipped models).

Gear Indicator

See Controls and Indicators → Instruments → Instruments (Fairing Models, typical). On equipped models, the currently selected gear (1-6) is displayed in the odometer window. The gear indicator is calculated from the vehicle speed and engine speed. The gear indicator remains blank when the transmission is in neutral, the clutch lever is pulled in or the vehicle is not moving.

The gear indicator may be momentarily inaccurate depending on rider clutch use characteristics and clutch wear. This can occur if the clutch is allowed to slip either due to excessive wear, misadjusted clutch or if the operator rides the clutch.

ABS Lamp

WARNING

If ABS lamp continues flashing at speeds greater than 5 km/h (3 mph) or remains on continuously, the ABS is not operating. The standard brake system is operational, but wheel lock up can occur. Contact a Harley-Davidson Dealer to have ABS repaired. A locked wheel will skid and can cause loss of vehicle control, which could result in death or serious injury. (00361b)

Flashing: See Controls and Indicators → Instruments → Instruments (Fairing Models, typical) and Controls and Indicators → Instruments → Instruments: FLHR. On vehicles with ABS, the ABS lamp begins flashing when the vehicle is turned on. The flashing lamp indicates that the system is in self-diagnosis mode. It continues to flash until motorcycle speed exceeds 5 km/h (3 mph). ABS is not operational until the lamp turns off.

Solid: Continuous illumination of the lamp indicates an ABS malfunction. ABS is disabled and the brakes are operating as if they were non-ABS brakes. See a Harley-Davidson dealer for service.

Engine Coolant Temperature Lamp

NOTICE

If the engine coolant temperature indicator lamp remains lit, always check the coolant level. If the coolant level is normal and the lamp is still lit, stop the engine at once and do not ride further until the trouble is located and the necessary repairs are made. Failure to do so may result in engine damage. (00158a)

WARNING

Do not loosen or remove pressure cap when cooling system is hot. The cooling system is under pressure and hot coolant and steam can escape from pressure cap, which could cause severe burns. Allow motorcycle to cool before servicing the cooling system. (00091c)

On Twin-Cooled vehicles, the engine coolant temperature lamp is on when the coolant has exceeded threshold temperature.

Check and add coolant as necessary. See Maintenance and Lubrication → Cooling System. For other possible coolant system issues, see Troubleshooting → Cooling System: Twin-Cooled Models.

If coolant level is sufficient and the lamp remains on, stop the engine immediately and see a Harley-Davidson dealer for service.

Oil Pressure Lamp

NOTICE

If the oil pressure indicator lamp remains lit, always check the oil supply first. If the oil supply is normal and the lamp is still lit, stop the engine at once and do not ride further until the trouble is located and the necessary repairs are made. Failure to do so may result in engine damage. (00157a)

See Controls and Indicators → Instruments → Instruments (Fairing Models, typical) and Controls and Indicators → Instruments → Instruments: FLHR. The oil pressure lamp turns on when the ignition is turned on. The lamp remains on until the engine is started.

If the lamp is on while the engine is running, sufficient oil is not circulating through the engine.

Check and add engine oil as necessary. See Maintenance and Lubrication → Engine Oil Level. For other possible causes, see Troubleshooting → Engine.

If the engine oil level is sufficient and the lamp remains on, stop the engine immediately and see a Harley-Davidson dealer for service.
