speedometer not working after battery change
Speedometer not working after battery change:
1.The fuse and relay of constant speed cruise fail, and the system cannot work;
2.Failure of cable harness;
3.Constant speed cruise key contact is worn;
4.Engine or gearbox problems;
5.The constant speed cruise switch is damaged and the circuit is faulty (such as brake pedal sensor fault, wheel speed sensor fault and related circuit fault);
6.ECU cannot receive the signal of cruise solenoid valve.
Its because:
1. The plug of the speed sensor is loose.
2. The speedometer on the instrument panel is not in good contact.
3. The instrument control circuit is broken or the indicator on your instrument is broken.
4. The solution is to send the repair shop to a professional for maintenance or directly replace the odometer.
5. Electric vehicles are electric vehicles, also known as electric vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles.
6. Generally speaking, the electric vehicle is a vehicle that takes the battery as the energy source and converts the electric energy into mechanical energy through the controller, motor and other components to control the current and change the speed.
There are many reasons for not working:
1. It may be because the vehicle speed is too low or too high. Because constant speed cruise requires vehicle speed, the constant speed cruise system can work normally only within the range of more than 40km / h and less than 120km / h.
2. The switch of the constant speed cruise system is broken, or the relevant circuit is faulty, such as wheel speed sensor fault, brake pedal sensor fault, etc. In this case, it is recommended to go to a 4S store or an automobile repair shop for inspection and repair.
3. There is a problem with the computer software of the constant speed cruise system. It is recommended to contact the official customer service to see if the system can be restored, upgraded or optimized. If it cannot be solved, go to the 4S store for maintenance.Constant speed cruise system, also known as speed control system, auto drive system, etc., is a driving assistance system. When the driver turns on the constant speed cruise system on the road section with good road conditions and few vehicles, the driver does not need to step on the accelerator pedal, which reduces the driver's fatigue and saves fuel. When starting the constant speed cruise, if the driver steps on the accelerator or brake, the constant speed cruise will automatically close.
