Why does the Lavida dashboard speed keep flashing?
3 Answers
Lavida dashboard speed keeps flashing because the overspeed warning is set. The importance of overspeed warning: The ultimate purpose of vehicle speed limit is to prevent greater personal injuries and unnecessary safety accidents caused by driving too fast. Safe driving is everyone's responsibility during the journey. How to modify the overspeed warning: Press the right wiper lever, first press button a to reset the warning speed. Then toggle the upper end of switch B to increase the warning speed. Directly increase it to the desired speed - each press increases by 5km, then press button a again to confirm the setting.
My old Lavida had the same issue—the speedometer needle suddenly jumping around, which was quite scary. It was especially severe last winter, always happening when starting the cold engine. Later, I took it to a repair shop and found out the speed sensor connector was loose, causing poor contact. The mechanic said the sensor on the Lavida is located near the tires, and frequent bumps on rough roads can easily loosen it. Additionally, if the wheel speed sensor itself is faulty, it can cause unstable signals, making the needle flicker erratically. I suggest you first check the sensor connector under the chassis—unplug it and reconnect it firmly. If that doesn’t work, you’ll need to replace the sensor. Genuine OEM parts on Taobao cost around 100+ yuan. Also, try to slow down when driving over potholes to protect the sensor connector.
I've been driving my Lavida for five years, and recently the speed on the dashboard keeps flashing. I asked a friend who works in automotive electronics to take a look. He connected his computer to the OBD port to read the fault codes, which showed an abnormal signal from the right front wheel speed sensor. My friend explained that such issues are usually caused by three reasons: the sensor is dirty with mud or water leading to signal errors, the sensor wiring is worn or broken, or the signal is affected by electromagnetic interference. The sensors on rear-wheel-drive Lavida models are particularly prone to dust buildup, so it's recommended to clean the inside of the wheel hubs every six months. Additionally, if you've installed aftermarket navigation or dash cams, they might interfere with the signal lines, so it's important to check if the wiring shielding is intact. Replacing the sensor isn't too difficult, but you need to make sure you buy the correct model. Just search online for the Lavida's part number before placing an order.
