What are the reasons why cruise control cannot be activated?
1 Answers
Cruise control cannot be activated for the following reasons: 1. The speed is not within the range of 40 to 200 kilometers per hour; 2. The cruise control switch is damaged; 3. There is a circuit malfunction; 4. The ECU cannot receive the signal from the cruise control solenoid valve. Cruise control automatically maintains the vehicle's speed at the desired level set by the driver without the need to press the accelerator pedal, allowing the car to travel at a constant speed. When driving on highways for extended periods, the driver no longer needs to control the accelerator pedal, reducing fatigue and unnecessary speed fluctuations, which can also save fuel. When the cruise control button is pressed, the car maintains the set speed. Pressing the brake pedal immediately deactivates this function. In addition to using the brake pedal to deactivate the function, other operations such as the parking brake, clutch, or speed adjustment lever can also deactivate it.
