See Controls and Indicators → Instruments → Instruments. The check engine lamp indicates the condition of the engine/engine management system.

The check engine lamp normally comes on when the motorcycle is first turned on. During this time, the engine management system runs a series of self-diagnostics.

If the engine lamp does not turn off after starting the engine or comes on at any other time, see a Harley-Davidson dealer.

Solid: See Controls and Indicators → Instruments → Instruments. 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.

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

See Controls and Indicators → Instruments → Instruments. The security lamp displays the status of the security system and electrical self-diagnostics for the motorcycle. See 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, a diagnostic trouble code exists. See a Harley-Davidson dealer.

Flashing: See Controls and Indicators → Instruments → Instruments. 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.

See Controls and Indicators → Instruments → Instruments. The headlamp high beam lamp is on when the high beam or flash to pass switch is activated.

See Controls and Indicators → Instruments → Instruments. The neutral lamp is on when the transmission is in neutral.

Off: See Controls and Indicators → Instruments → Instruments. 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.

See Controls and Indicators → Instruments → Instruments. The auxiliary/fog lamp indicator is on when the auxiliary/fog lamps are turned on.

See Controls and Indicators → Instruments → Instruments. 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 and clutch wear. This can occur if the clutch is allowed to slip due to excessive wear, misadjusted clutch or the operator riding the clutch.

Flashing: See Controls and Indicators → Instruments → Instruments. 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 non-ABS brakes. See a Harley-Davidson dealer for service.

See Controls and Indicators → Instruments → Instruments. The engine coolant temperature lamp is on when the coolant has exceeded threshold temperature.

Check coolant. 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. See a Harley-Davidson dealer for service.

See Controls and Indicators → Instruments → Instruments. The oil pressure lamp turns on when the motorcycle 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 engine oil. Add oil as necessary. See Maintenance and Lubrication → Check 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. See a Harley-Davidson dealer for service.

See Controls and Indicators → Instruments → Instruments. The low tire pressure/TPMS malfunction lamp indicates when a low tire pressure condition or a TPMS system malfunction has occurred.

Flashing (60 seconds, followed by solid lamp): TPMS malfunction has been detected. The security lamp also turns on to show that a diagnostic trouble code exists. This event can occur for a variety of reasons, including loss of signal from the sensors or sensor battery failure. Tire pressure data may not be available while the lamp is lit. See a Harley-Davidson dealer for service.

Solid: The system has detected that one or more tires have low pressure. The radio will also indicate details for this condition. Safely stop the vehicle and use a tire pressure gauge to check the pressure of each affected tire. Inflate the tires according to specifications in Specifications → Specifications → Specified Tires or as specified on the label on the frame downtube. The lamp will turn off when you begin riding the motorcycle with the correct pressure in the tires. Also refer to Specifications → Tire Data → Tire Pressure Adjustment to compensate tire pressures for tires that have recently been ridden. If tire pressure is adjusted per Specifications → Tire Data → Tire Pressure Adjustment, readjust per cold tire recommendation at the earliest convenience.

See Controls and Indicators → Odometer Functions for tire pressure data displayed in the odometer.

See Controls and Indicators → Boom! Box Vehicle Status and the BOOM! BOX OWNER'S MANUAL for TPMS functions in the radio.
