DESCRIPTION

Each speed sensor detects wheel speed and sends signals to the skid control ECU (brake actuator assembly). These signals are used by the ABS.

Tech Tips

The output voltage values shown below are for when the vehicle wire harnesses are connected to the skid control ECU (brake actuator assembly) and the speed sensors.
