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 control.

HINT:

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.
