Solution

1. Preparation

Gather necessary tools and components for repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the vehicle battery to ensure safety while working on electrical systems.

2. Inspect and Repair Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Check for dirt, corrosion, or physical damage.
If damaged, remove the faulty sensor:
- Use a socket set to remove the mounting bolt.
- Disconnect the electrical connector.
Install the new sensor:
- Connect the electrical connector securely.
- Torque the mounting bolt to manufacturer specifications (consult repair manual for exact torque values).

3. Check ABS Module

Locate the ABS module, usually found near the master cylinder.
Inspect wiring and connectors for corrosion or damage.
Clean any corrosion with an electrical contact cleaner.
If the module is faulty, replace it:
- Disconnect the battery and electrical connectors.
- Unbolt the ABS module from its mount.
- Install the new module and reconnect all wiring.

4. Reconnect Battery and Test
