The reason the steering wheel feels lighter is due to a malfunction in the computer controlling the electronic power steering. Below is additional information about the electronic power steering system: 1. Structure: The system mainly consists of components such as a torque sensor, vehicle speed sensor, electric motor, reduction mechanism, and electronic control unit. 2. Working Principle: When the steering wheel is turned, the torque sensor detects the direction and magnitude of the steering torque. The electronic control unit then uses data such as vehicle speed and steering direction to control the motor to output corresponding magnitude and direction of assistance. Since the motor does not operate when the vehicle is not turning, this also significantly reduces energy consumption. 3. Advantages: Because the electric power steering system is powered by electricity, it can operate independently of the engine, reducing fuel consumption while providing better handling and comfort.

Does the Mitsubishi ASX have front and rear anti-collision beams?

Mitsubishi ASX is equipped with front and rear anti-collision beams. The main body of the beam is made of bake-hardened steel with a tensile strength of approximately 1300Mpa, while the beam brackets connected to it are constructed from solution-treated aluminum alloy with a strength of about 300Mpa. Here's some information about anti-collision beams: An anti-collision beam is a device designed to absorb collision energy during impacts. It consists of a main beam, energy absorption boxes, and mounting plates that connect to the vehicle. Both the main beam and energy absorption boxes can effectively absorb collision energy during low-speed impacts, minimizing damage to the vehicle's longitudinal beams and protecting the car body.
