Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, cleaning materials.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Addressing Faulty Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Disconnect the electrical connector from each sensor.
3. Use a multimeter to check the resistance of the sensors; compare readings against manufacturer specifications.
4. Clean any debris or corrosion from the sensor connectors and the mounting areas.
5. If a sensor is faulty, replace it with a new one and reconnect the electrical connector.

3. Inspecting the ABS Control Module

Sub-steps:
1. Locate the ABS control module, typically found near the brake master cylinder.
2. Inspect the module for any visible signs of damage, corrosion, or loose connections.
3. If necessary, disconnect the module and clean the connector pins with electrical contact cleaner.
4. Reconnect the module and ensure all connections are secure.

4. Check Brake Fluid Level

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; if it’s below the minimum mark, add the appropriate brake fluid type as specified in the owner’s manual.
3. Inspect for any leaks in the brake lines or around the master cylinder.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals once all repairs are made.
Use the OBD-II scanner to clear any stored ABS error codes.
Test drive the vehicle to ensure the ABS light does not reappear.
