Wheel speed and acceleration sensor (Mitsubishi L200 4)

Wheel speed sensors consist of ABS rotors that rotate at the same speed as the wheels, and stationary sensors that detect how fast the rotors rotate.

Acceleration sensor

The acceleration sensor, located at the bottom of the vehicle, detects positive (increasing speed) or negative (decreasing speed) acceleration of the vehicle using a semiconductor element and sends the corresponding data to the ABS-ECU.
