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.
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 Hands-Free Security Module → HARLEY-DAVIDSON SMART SECURITY SYSTEM.
If the electrical system lamp remains lit after the security system is disarmed, check all the motorcycle lamps for a failed bulb and replace as needed. If all bulbs are working and the electrical system lamp remains lit, see a Harley-Davidson dealer.
Anti-Lock Brake System (ABS) Lamp
Flashing: See Controls and Indicators → Instruments → Instruments. On ABS equipped models, the amber ABS indicator lamp flashes when the ignition switch is turned to ignition (IGN) to indicate that the system is operational. It continues to flash until motorcycle speed exceeds 3 mph (5 km/h).
Solid: Continuous illumination of the lamp indicates a malfunctioning ABS system. The ABS is disabled and the brakes are operating as if they were non-ABS brakes. See a Harley-Davidson dealer for service.
WARNINGIf 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)
