Right Front Wheel Speed Sensor Circuit Short to Battery (C050612)
DESCRIPTION
Each speed sensor detects wheel speed and sends signals to the
skid control ECU (brake actuator assembly). These signals are used by the brake
control.
The speed sensor detects the magnetic fields of the speed sensor
rotor as it rotates and outputs a pulse signal.
