Installation Guidelines

The Vemo V30-72-0130 is engineered for straightforward integration into a vehicle’s wheel hub assembly. Follow these steps to ensure optimal performance:

1. Preparation: Verify that the wheel hub is clean and free of debris. Remove any old sensor or mounting hardware.
2. Alignment: Position the sensor so that its magnetic field aligns with the wheel’s rotating element (typically a toothed rim or gear). Use the manufacturer’s alignment jig if available.
3. Securing: Fasten the sensor with the supplied bolts, ensuring a torque of 10–15 Nm (adjust according to vehicle specifications).
4. Electrical Connection: Connect the sensor’s wiring harness to the vehicle’s control module. Verify polarity and secure all connections against vibration.
5. Testing: After installation, perform a diagnostic check using the vehicle’s OBD‑II port or dedicated scan tool to confirm that wheel speed data is being transmitted correctly.
