ABS 30548 Wheel Speed Sensor

ABS 30548 Wheel Speed Sensor

The ABS 30548 Wheel Speed Sensor is a precision component designed to monitor the rotational speed of each wheel in an automotive vehicle. By providing real‑time data to the Anti‑Lock Braking System (ABS), it enables safe and efficient braking under various driving conditions.

Key Functions

• Speed Detection: Measures wheel rotation frequency with high accuracy.
• Signal Transmission: Sends a calibrated electrical signal to the ABS control module.
• Fault Identification: Detects anomalies such as sensor failure or wheel slip, triggering appropriate system responses.

Technical Specifications

Installation Guide

Installing the ABS 30548 Wheel Speed Sensor requires careful alignment and secure mounting to ensure optimal performance. Follow these steps:

1. Preparation: Disconnect the vehicle’s battery to prevent accidental electrical discharge.
2. Remove Old Sensor: Use a suitable socket or wrench to detach the existing sensor from the wheel hub. Note any wiring harness connectors for reuse.
3. Clean Mounting Surface: Inspect and clean the hub flange to remove debris, rust, or old adhesive residue.
4. Position New Sensor: Align the sensor’s magnetic pole with the wheel’s rotating metal plate. Ensure the sensor housing sits flush against the hub flange.
5. Screw Securely: Tighten mounting bolts to the manufacturer’s torque specification (typically 10–15 Nm).
6. Reconnect Wiring: Attach the sensor’s connector to the vehicle’s harness, ensuring a snug fit and proper polarity.
7. Test Functionality: Reconnect the battery and activate the ABS system. Verify that the sensor registers wheel speed correctly via diagnostic tools or visual indicators on the dashboard.
