Highlander cruise is not available. What's going on here?

The reason why Highlander cruise of Pacific automobile network can't be used: 1, the fuse and relay of cruise control are out of order, and the system can't work; 2. Cable harness failure; 3, constant speed cruise button contact wear; 4. There is something wrong with the engine or gearbox; 5. The cruise control switch is damaged, resulting in circuit failure (such as brake pedal sensor failure, wheel speed sensor failure and related circuit failure, etc. ); 6.ECU cannot receive the signal of cruise solenoid valve.

20 15 Highlander has a fixed speed cruise. The reason why cruise with constant speed is equipped is to reduce the fatigue of drivers, avoid the fluctuation of engine speed, improve fuel economy, and at the same time accurately control the driving speed of cars to avoid speeding.

Toyota Highlander cruise at fixed speed; Highlander cruise can be started by the steering wheel; Toyota Highlander adopts cruise control, which can keep the speed above 30km/h and below 150km/h, without stepping on the accelerator all the time.

Highlander four-wheel drive 7-seat elite version has no fixed-speed cruise;

1, CRUISECONTROLSYSTEM is abbreviated as CCS, also known as cruise driving device, speed control system, automatic driving system, etc.

2. The cruise control system is mainly composed of control switch, control module (cruise computer) server (actuator). The working principle of the cruise control system is simply that the cruise control module reads the pulse signal sent by the speed sensor and compares it with the set speed, so as to adjust the increase or decrease of the throttle opening and keep the vehicle at the set speed all the time;

3. For example, when the vehicle goes uphill, the speed drops and the pulse signal from the speed sensor drops, and the control module will instruct the servo actuator to open the throttle valve at the corresponding angle to maintain the speed. On the contrary, when going downhill, the throttle opening will decrease.
