Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
Ensure the vehicle is parked on a level surface, and engage the parking brake. Disconnect the battery to avoid electrical shorts.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Lift the vehicle and remove the wheel covering the ABS sensor.
2. Disconnect the ABS sensor connector.
3. Clean any debris around the sensor and inspect for damage.
4. Measure the resistance of the sensor using a multimeter (should typically be between 1,000 and 2,000 ohms).
5. If the resistance is out of specification, replace the sensor.

3. Check ABS Module and Wiring

Sub-steps:
1. Locate the ABS control module, usually found near the brake master cylinder.
2. Inspect the wiring harness for any signs of fraying or corrosion.
3. Reconnect any loose connectors and ensure they are secure.
4. Use a multimeter to check for proper voltage and ground at the ABS module.

4. Brake Fluid Inspection

Sub-steps:
1. Check the brake fluid reservoir for proper fluid level.
2. If low, top off with the manufacturer-specified brake fluid (usually DOT 4).
3. Inspect the condition of the brake fluid; if contaminated, perform a brake fluid flush.

5. Reconnect Battery and Clear Codes

Sub-steps:
1. Reconnect the battery terminals securely.
2. Use the OBD-II scanner to clear any stored ABS fault codes.
3. Start the vehicle and check if the ABS light remains off.
