Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake cleaner, torque wrench
Gather necessary replacement parts based on diagnostic findings.

2. Inspect ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Sub-steps:
1. Remove the wheel to access the sensor.
2. Disconnect the sensor's electrical connector.
3. Clean the sensor and mounting area with brake cleaner.
4. Check the sensor's resistance using a multimeter; replace if faulty.
5. Reconnect the sensor and reattach the wheel.

3. Check ABS Module and Wiring

Inspect the ABS module located under the hood.
Sub-steps:
1. Disconnect the battery to avoid electrical shorts.
2. Inspect the ABS module connectors and wiring for corrosion or damage.
3. Clean any corroded connectors with electronic cleaner.
4. Reconnect everything and restore battery power.

4. Brake Fluid Inspection

Check the brake fluid reservoir.
Sub-steps:
1. Ensure the fluid is at the correct level and is not dark or contaminated.
2. If the fluid is low, top it up with the manufacturer-recommended brake fluid.
3. If contamination is present, perform a brake fluid flush.

5. Test Drive and Check Functionality

After repairs, perform a test drive.
Sub-steps:
1. Monitor for ABS light and ensure it remains off during and after the drive.
2. Test braking performance and responsiveness.
