The first cause of the car's speedometer light is off is from the electrical panel. This is because the dashboard display is closely related to the car's electrical system.

However the indicator light on the speedometer is directly related to electricity. So if the electrical system experiences a short circuit or error, the car speedometer light turns off.

So you must immediately find a way to fix the dead car speedometer light, the car speedometer light is off, so that the indicators in the speedometer can work properly.

2. Error Panel

Then, apart from electricity, another cause is damage to the panel. Panels with automatic errors make the hint indicator turn off. If only one panel is damaged, this will still affect the indicator indicator. Fortunately, now checking the condition of the speedometer panel can be done easily.

You can use a tool called the scan tool to find out which parts of the speedometer panel are damaged or have errors. If the damage is found, immediately replace the panel with a new one to optimize vehicle performance.

3. the Sensor Is Damaged, Also the Cause of the Car Speedometer Light Is Off

Next is the problem with the speedometer sensor that you can find on vehicles with electronic sensors. This sensor is placed on the transmission.

So, if the vehicle speed sensor is damaged, the socket is loose and detached, until the transducer gear is worn, then the vehicle speed cannot be predicted.

The presence of damage also makes the check engine light turn on on most Engine Fuel Injection (EFI) cars.

Then, on the type of vehicle with ABS brakes, speed sensors are also installed on the wheels. So that the ABS is damaged, then it definitely makes the speedometer die.

7. Anti-Lock Brake System

In addition to the SRS, the speedometer also has an indicator light for the anti-lock brake system to keep the car's braking system from being locked during sudden braking.

When the tires are locked, then accidents can occur because the car loses control. In ABS technology there is an indicator light that will light up when the ABS brake system is working. But you need to find out more if the ABS indicator keeps on, it means there are other problems that need to be fixed.

The causes can be various, such as reduced car brake fluid, problems with the speed sensor, cable problems in the engine, or others.

8. Tire Pressure

If the tire pressure when traveling is less, then for modern cars today there is an indicator on the speedometer. Normal tire pressure is needed to make driving comfortable, reduce friction, and increase safety.

The indicator contains instructions on the tire pressure according to the condition of the car. In this case, it is important for you to take this indicator into consideration before driving.

Speedometer Function

Outside of the discussion about why the car speedometer light is off. Let's agree first to understand the function of the speedometer.

If you are not familiar with the speedometer, this component is usually located behind the car steering wheel or at the top of the motorcycle handlebar.

Through the speedometer, motorized vehicle drivers can find out various things related to the condition of the vehicle. In addition to monitoring vehicle speed, on the speedometer there are also many notifications that display several car components.

So there are many functions of the speedometer, which can be explained as follows.

  1. Knowing information about the capacity or volume of fuel.
  2. View information about the speed of the vehicle so that the driver can adjust the vehicle speed optimally.
  3. The speedometer displays information about the position of the automatic transmission gear and shows the condition of the vehicle's lights, either on or off.
  4. Get information about the distance traveled in kilometers.
  5. As a driver, you can also find out information about the vehicle's engine temperature through the speedometer.

So, the existence of a speedometer is not just to beautify the appearance of the vehicle, but to present various important information related to the vehicle.
