Antilock Brakes / Traction Control Systems: Description and Operation

This model is equipped with rear wheel ABS. The ABS control unit senses the drop in rear wheel speed and modulates hydraulic pressure to the rear brakes, inhibiting lockup. The rear wheel ABS is composed of electrical and mechanical components (hydraulic unit), and the components of the standard brake system. Any malfunction of the ABS electrical or mechanical components is judged by the self-diagnosis function in the ABS control unit. All malfunctions are indicated by the warning lamp in the instrument panel. The location of a malfunction is indicated to the technician by a flashing pattern of the ABS warning lamp. The self-diagnosis and indication functions must be used when diagnosing malfunctions of the ABS.
