Wheel Sensor Signal Processing
WARNING: This page is about a different car, the 2007 Kia Sedona and 2006 Kia Sedona. However, it is still accessible from the selected car via links, so may be relevant.
The ECU shall receive wheel speed signal from the four active wheel sensors.
The wheel signals are converted to voltage signal by the signal conditioning circuit after receiving current signal from active wheel sensors and given as input to the MCU.
