A.B.S 31150 Brake Sensor

The A.B.S 31150 is a high‑performance wheel speed sensor designed for the anti‑lock braking system of modern passenger vehicles. It provides precise wheel rotation data to the vehicle’s electronic control unit (ECU), enabling optimal brake modulation and safe handling during emergency stops.

Key Functionalities

• Accurate Wheel Speed Detection: Measures rotational speed of each front wheel with high resolution, ensuring the ABS system can react instantly to loss of traction.
• Active Sensor Design: Generates a signal directly to the ECU without requiring external power, reducing wiring complexity and improving reliability.
• Robust Construction: Encased in a weather‑sealed housing that protects against dust, water, and temperature extremes typical of automotive environments.
• Low Power Consumption: Operates efficiently to preserve battery life while delivering consistent performance.

The sensor is engineered for a wide range of models, including but not limited to:

• Chevrolet – Cruze, Volt, Ampera, Orlando
• Opel – Astra J (various engine sizes), Zafira C, Meriva B, Sports Tourer, Caravan
• Vauxhall – Astra VI, Zafira III, Ampera, Orlando

It is available as a single unit or in a pair for front‑axle installation (left and right). The sensor’s dimensions and mounting points are compatible with OEM specifications across these platforms.

1. Remove the wheel: Safely lift the vehicle and detach the wheel to access the hub assembly.
2. Detach the existing sensor: Unscrew or unclip the old sensor, noting its orientation for correct placement of the new unit.
3. Mount the A.B.S 31150: Align the sensor’s mounting flange with the hub and secure it using the supplied fasteners. Ensure the sensor is seated flush to avoid misalignment.
4. Connect wiring harness: Attach the sensor’s connector to the vehicle’s ECU harness, matching pins precisely to preserve signal integrity.
5. Reinstall wheel and test: Replace the wheel, lower the vehicle, and perform a diagnostic check to confirm the sensor is functioning within expected parameters.

• Enhanced Safety: By delivering precise wheel speed data, the ABS system can modulate brake pressure more accurately, preventing wheel lock‑up and maintaining steering control.
• Durability: The sensor’s robust construction resists vibration, corrosion, and thermal cycling, ensuring long‑term reliability.
• Ease of Maintenance: Its standardized mounting interface allows quick replacement without specialized tools.

The A.B.S 31150 undergoes rigorous testing at multiple stages: component verification, functional validation under simulated driving conditions, and final quality inspection. Each unit is stamped with a unique serial number for traceability and compliance with automotive safety standards.

For drivers seeking dependable anti‑lock braking performance, the A.B.S 31150 Brake Sensor offers a blend of precision, durability, and compatibility across a broad spectrum of popular vehicle models. Its active design and robust construction make it an ideal choice for both OEM installations and high‑quality aftermarket replacements.
