Quick answer

Service Data - Bendix WS-24 Antilock Wheel Speed Sensor The Bendix WS-24 Wheel Speed Sensor (WSS) is an electromagnetic device used to obtain vehicle speed information for an antilock controller. When the wheel rotates, the sensor and an exciter ring (sometimes called a rotor or tone ring) generate a simple AC signal. This signal is sent to either the brake controller (Bendix EC-60 or Bendix EC-80) or the Global Scalable Brake Control electropneumatic modulator (Bendix GSBC EPM-90), which analyzes the data and commands the Antilock Braking System (ABS) accordingly. Specifically, the WSS consists of a coil, pole piece, and a magnet. The exciter ring is a steel ring or gear-like device that has regularly spaced high and low spots called teeth. The WSS is mounted in a fixed position, while the exciter ring is installed on a rotating member (typically part of the hub) so that its teeth move, in close proximity, past the tip of the sensor

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.

No. A recall is a safety campaign with a required remedy for affected VINs. A service bulletin or manufacturer communication usually describes diagnostic, repair, software, warranty or service information.

How should a used-car buyer use this bulletin?

Use it as a research signal. Compare it with recalls, owner complaints, service records, a VIN report and an independent inspection before buying.
