Check Engine Lamp
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.
Security Lamp
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.
Turn Signal Indicator Lamps
Rapid flashing: A turn signal bulb is not operating. Exercise caution and use hand signals. Replace inoperative components at earliest opportunity.
Gear Indicator
See
Operation → Instruments → Instruments and Indicator Lamps. 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.
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
Operation → Instruments → Instruments and Indicator Lamps. 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.
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)
If the lamp is on while the engine is running, sufficient oil is not circulating through the engine.
If the engine oil level is sufficient and the lamp remains on, stop the engine immediately. See a Harley-Davidson dealer for service.
Low Tire Pressure/TPMS Malfunction Lamp

WARNING
Be sure tires are properly inflated, balanced, undamaged, and have adequate tread. Inspect your tires regularly and see a Harley-Davidson dealer for replacements. Riding with excessively worn, unbalanced, improperly inflated, overloaded or damaged tires can lead to tire failure and adversely affect stability and handling, which could result in death or serious injury. (00014b)
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
Service Procedures → Tires to compensate tire pressures for tires that have recently been ridden. If tire pressure has been adjusted per
Service Procedures → Tires, readjust per tire recommendation at the earliest convenience.
NOTE
Do not use the TPMS system as a pressure gauge when adding or removing air from a tire. Sensor data is sent to the TPMS at varying intervals (depending on whether the vehicle is in motion, parked on the jiffy stand, or has a significant change in tire pressure). The tire pressure data may not refresh immediately when adding or removing air from the tire. Over or under-inflation can result.
