Why doesn't the car dashboard display speed in kilometers?

[BenjaminRose]

There are many possible reasons why a car's dashboard does not display speed in kilometers: 1. Faulty wheel speed sensor/vehicle speed sensor: This issue can be diagnosed by using a decoder to read data streams, lifting the vehicle, and rotating the wheels to check for wheel signals. 2. Signal transmission problems: Issues such as open circuits or short circuits in the wiring. 3. Check the speedometer flexible core: Inspect whether the connection device between the transmission and the speedometer is broken. 4. Check the odometer gear on the transmission: Verify if the odometer gear on the transmission is malfunctioning.

I've been driving for over a decade and have encountered issues with the dashboard speed display disappearing. This is usually due to a faulty speed sensor, such as when the sensor near the wheels gets dirty or damaged, preventing the signal from reaching the dashboard. Worn-out or short-circuited wiring can also cause unstable electrical currents. Another possibility is a blown fuse cutting off the power supply. I recommend first checking the fuse box in the engine compartment to see if the corresponding fuse is blown—sometimes a simple replacement can fix the issue. If that doesn't work, don't risk driving; not knowing your speed is dangerous as you might unknowingly exceed speed limits. Head to a professional repair shop immediately to fix the sensor or wiring. Address the problem promptly—safety comes first. Driving without a speed display is like walking blindfolded.

As a regular commuter driver, I panic when the dashboard doesn't display the speed in kilometers. Possible causes include sensor failure or poor wire connections, especially in older vehicles where wiring tends to loosen. A blown fuse is another common issue - simply replacing it often solves the problem. For modern cars with digital dashboards, software glitches may cause display errors; try restarting the vehicle as this can sometimes instantly restore functionality. Regardless, avoid speeding as it increases accident risks. Pull over to check fuses or go directly for repairs - don't let the issue linger and disrupt your journey.

From my car repair experience, when the car dashboard doesn't display speed, it's often due to a faulty wheel speed sensor or damaged wiring inside the instrument cluster. Loose wire connectors or blown fuses could also be the cause. For digital dashboards, software bugs may prevent speed updates. I recommend not ignoring this issue - use an OBD scanner to check error codes as soon as possible to identify the root cause. Attempting DIY repairs might backfire, so it's better to have a technician handle it. For safety, change lanes slowly and drive cautiously until the issue is fixed.
