Check Engine Lamp

See Controls and Indicators → Instruments → Instruments. The check engine lamp indicates when the engine/engine management system is not operating normally.

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

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

Low Fuel Lamp

Solid: See Controls and Indicators → Instruments → Instruments. The low fuel warning lamp illuminates when the gasoline in the tank reaches the low fuel level (approximate) shown in Specifications → Specifications → Capacities.

Flashing: If the low fuel lamp flashes continuously, it indicates the presence of a fault in the fuel level circuitry. See a Harley-Davidson dealer.

Battery Discharge Lamp

See Controls and Indicators → Instruments → Instruments. The battery lamp indicates either overcharging or undercharging of the battery. Refer to Maintenance and Lubrication → Battery Maintenance.

Electrical System Lamp

See Controls and Indicators → Instruments → Instruments. On motorcycles equipped with a security system, the electrical system lamp will illuminate when the security system is armed. Refer to SECURITY SYSTEM → Security System.

If the electrical system lamp remains lit after the security system is disarmed see a Harley-Davidson dealer.

Anti-Lock Brake System (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. 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.
