Figure 6. Indicator lights: 1. Turn left; 2. High beam; 3. Neutral position; 4. Low oil pressure indicator; 5. Low engine coolant level indicator; 6. Turn right; 7. Low fuel indicator; 8. Security system malfunction indicator; 9. ABS system operation indicator; 10. Alternator fault indicator; 11. Indicator of engine problems registered by the motorcycle’s on-board computer
See Figure 6. There are eleven indicator lights on the instrument panel.
Two green turn indicators - flash when the turn signals are on; flashes indicate the selected direction of rotation. When the motorcycle's warning lights are operating, both turn indicators flash simultaneously.
If the blue high beam indicator light is illuminated, this indicates that the headlight is high beam.
If the green neutral light is illuminated, it indicates that the transmission is in neutral.
If the red low oil pressure indicator light is illuminated, this indicates that oil is not circulating through the engine.
If the red high engine coolant temperature indicator is illuminated, the engine temperature is greater than 243°F (117°C).
If the engine diagnostic light is red, this means that the motorcycle's on-board computer has detected an engine problem.
If the red alternator light is on, it means that the circuit through which charging current flows is faulty and the battery is not charging properly.
The security status indicator shows the status of the motorcycle's security system. This indicator also lights up if a security system is not installed on the motorcycle.
The yellow low fuel indicator lights up when the fuel tank is almost empty.
On motorcycles equipped with ABS, the orange ABS indicator light will flash when the ignition key switch is in the ON position, indicating that the system is operational.
The lamp continues to flash until the motorcycle speed exceeds 5 km/h (3 mph). The lamp only illuminates continuously when the ABS detects that the system is inoperative. In diagnostic mode, the lamp glows to indicate that there are diagnostic messages about problems (With codes) DTCs (diagnostic trouble codes). See your Harley-Davidson dealer for service.
Warning! If the ABS light stays on, it means the ABS system is not working. The standard braking system is functional, but the wheels may lock (become immobile). To have the ABS system repaired, take it to your Harley-Davidson dealer for service. If even one wheel is locked, the motorcycle may lose control, which could result in serious injury or death.
Notes:
- The low oil pressure indicator light will illuminate if the ignition is turned on before the engine is started. If the engine is idling, this lamp should not light up.
- For more information about the safety system status indicator lamp, see the Harley-Davidson Safety System section below.
There are several other circumstances under which the red low oil pressure warning light will illuminate, including the following:
- Insufficient oil or diluted oil - in this case, the low oil pressure indicator light illuminates in any gear except idle.
- In freezing weather, oil flow may be cut off because the oil line is clogged with ice and thickened oil, stopping oil circulation.
- Oil signal switch wire short circuit.
- Oil signal switch failure.
- The control valve is incorrectly installed or faulty.
- Problems with the oil pump.
Warning! If the low oil pressure indicator light stays on, always check the oil supply first. If the oil supply is normal and the lamp remains illuminated, stop the engine immediately and do not continue driving until the fault has been located and the necessary repairs have been made. Failure to do so may result in engine failure.
There are several circumstances under which the red high coolant temperature indicator light will illuminate, including the following:
- The cooling fan is faulty.
- Low amount of refrigerant.
- Thermostat is faulty.
- The temperature measuring device is faulty.
- Foreign objects have entered the refrigerant circuit and disrupted the refrigerant circulation.
- The radiator cap is faulty.
- There is a malfunction in the circuit through which the refrigerant circulates.
Warning! If the engine coolant indicator light is on, always check the coolant level. If the coolant level is normal and the light remains on, stop the engine immediately and do not drive until the problem has been corrected and necessary repairs have been made. Failure to do so may result in engine failure.
Warning! If the engine is hot, do not remove the radiator cap. The cooling system is under pressure, and if the cap is removed, steam or hot coolant may escape from the cap, which may cause severe burns. Do not begin servicing the cooling system until the engine has cooled down.
