AUTLOG AS5104 Wheel Speed Sensor (ABS)

The AUTLOG AS5104 is a high‑performance Wheel Speed Sensor designed for the Anti‑Lock Braking System (ABS). It delivers precise wheel velocity data to the vehicle’s electronic control unit, ensuring optimal braking performance and safety. This sensor is engineered for durability in harsh automotive environments, providing reliable operation over extended mileage.

Key Functionalities

• Accurate Speed Detection: Measures wheel rotation with high precision, enabling the ABS controller to modulate brake pressure accurately.
• Wide Temperature Range: Operates effectively from –40 °C to +120 °C, suitable for both cold climates and hot engine compartments.
• Low Power Consumption: Consumes minimal electrical current, reducing load on the vehicle’s battery system.
• Robust Construction: Encased in a sealed housing that resists moisture, dust, and vibration, extending service life.

Technical Specifications

Compatibility and Applications

The AUTLOG AS5104 is engineered to fit a wide range of vehicles, particularly those requiring an ABS wheel speed sensor. Common applications include:

• Front and rear axle sensors for passenger cars.
• Rear ABS sensors for light trucks and SUVs.
• Replacement for OEM sensors in models such as the Jeep Cherokee (2002‑2005) and other similar platforms.

Its standardized connector and mounting design allow seamless integration with existing vehicle wiring harnesses, eliminating the need for custom adapters.

Installation Guide

1. Preparation: Disconnect the vehicle battery to prevent electrical shock. Remove the wheel and tire to access the sensor mounting area.
2. Remove Old Sensor: Unscrew the existing ABS sensor using a suitable socket. Carefully detach the wiring harness, noting the orientation of the connector pins.
3. Mount New Sensor: Align the AUTLOG AS5104 with the mounting bracket and secure it using the provided screws. Ensure the sensor is firmly seated to avoid vibration.
4. Reconnect Wiring: Plug the sensor’s connector into the vehicle’s harness, matching pin positions exactly. Verify that the connection is snug and free of debris.
5. Reassemble Wheel: Reinstall the tire and wheel, then tighten lug nuts to manufacturer specifications.
6. Testing: Reconnect the battery and start the engine. Use a diagnostic scan tool to confirm that the sensor is transmitting correct wheel speed data. Check for any ABS warning lights or error codes.

Maintenance Tips

• Inspect the sensor housing periodically for cracks or corrosion, especially in coastal or high‑humidity environments.
• Clean the sensor surface with a soft brush and mild solvent to remove dirt that may affect signal quality.
• Avoid using abrasive materials near the connector pins; they are delicate and can be damaged by excessive force.
