Purpose

The 35J18L‑2405115 ABS wheel speed sensor is a core signal‑collecting component for bus and coach ABS anti‑lock braking system. Installed at the wheel hub, it continuously captures real‑time wheel rotation speed data and sends the signal to the ABS control unit. The ABS system judges wheel locking risk according to the speed signal and adjusts braking force automatically. It prevents wheel lock‑up during emergency braking, improves vehicle braking stability and driving safety, and avoids traffic accidents caused by wheel skidding.

Product Features

This ABS wheel speed sensor is equipped with 2‑meter long integrated PVC cable and right‑angle metal sensing head, matched with metal fixing clip for installation. Adopt high‑strength metal probe structure, suitable for harsh under‑vehicle environment. Waterproof dust‑proof connector prevents water and mud from invading. It supports 12‑24V wide‑voltage application for bus electrical system. Stable signal output without distortion, original‑standard size for direct replacement of original spare parts.

Product Advantages

1. High measuring accuracy, sensitive induction, accurately feed back wheel speed changes for ABS system.

2. Excellent waterproof, dust‑proof and anti‑vibration performance, adapt to long‑time bumpy driving conditions.

3. Complete accessories with 2M ready‑made cable, no secondary wiring needed, save installation time.

4. Plug‑and‑play design, original matching size, convenient for after‑sales maintenance replacement.

5. Low failure rate, stable long‑term working performance, reduce after‑sales maintenance cost.

Installation Steps

1. Cut off vehicle power supply before installation, prepare matching installation tools.

2. Locate the old ABS wheel speed sensor at bus wheel hub, remove the metal fixing clip.

3. Unplug the waterproof connector of old sensor, then take out the old sensor probe from mounting hole.

4. Install the new 35J18L‑2405115 sensor probe into the mounting hole, fasten with the new metal fixing clip.

5. Route the 2‑meter cable reasonably, avoid pulling or squeezing the wire harness. Firmly insert the waterproof connector into vehicle matching socket.

6. Finish assembly, turn on vehicle power, test ABS system function to confirm normal speed signal output.

Notes

1. Installation and disassembly must be performed under power‑off status to avoid circuit short‑circuit and component damage.

2. Do not strike or bend the metal sensing probe, impact will cause internal sensor damage and signal failure.

3. Arrange wiring harness properly, keep away from high‑temperature components and sharp edges to prevent cable wear and aging.

4. Do not pull the harness forcibly, avoid cutting or modifying the original cable arbitrarily.

5. Check sensor and fixing clip regularly in daily maintenance. Replace parts timely if signal error, abrasion or damage appears.

6. Prevent mud, sand and corrosive liquid from long‑term erosion on sensor head and connector.

7. This sensor is specially for bus ABS anti‑lock braking system, do not use on non‑matching vehicle models.
