An apparatus and method for resistive short circuit immunity for wheel speed sensor interface on a braking system. In one embodiment the apparatus includes a first circuit for generating a first periodic signal based on first current transmitted to a wheel speed sensor and a second circuit for generating a second periodic signal based on second current, some or all of which is received from the wheel speed sensor. A circuit is provided for selecting the first periodic signal for output if a magnitude of the second current is greater than a magnitude of the first current, or the second periodic signal for output if a magnitude of the second current is not greater than the magnitude of the first current. The selected first or second periodic signal contains information relating to a speed of a wheel that is associated with the wheel speed sensor.
