Circuit Description

WARNING: This page is about a different variant/trim than selected.

The vehicle equipped with ABS detects a vehicle speed using the stability control ECU and wheel speed sensor. This sensor monitors a wheel rotation speed and sends the signal to the ECU.

The stability control ECU converts these wheel speed signals into a 4-pulse signal and outputs it to the ECM via the combination meter.

The ECM determines the vehicle speed based on the frequency of these pulse signals.
