Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set, screwdrivers)
Ensure the vehicle is parked on a flat surface and the engine is off. Engage the parking brake.

2. Address Faulty Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle and remove the wheel corresponding to the ABS light.
2. Locate the ABS wheel speed sensor, typically mounted near the brake rotor.
3. Disconnect the electrical connector from the sensor.
4. Use a multimeter to check the sensor resistance; it should typically read between 1,000 and 2,000 ohms. If outside this range, replace the sensor.
5. Clean the sensor and the mounting area with brake cleaner to remove debris.
6. Reconnect the sensor and wheel, then lower the vehicle.

3. Check and Replace ABS Fuse

Sub-steps:
1. Locate the fuse box (usually under the dashboard or in the engine compartment).
2. Identify the ABS fuse using the fuse diagram on the cover.
3. Remove the fuse and inspect it for any breaks; replace it if necessary.
4. Reinsert the fuse and ensure it is seated properly.

4. Inspect and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder reservoir.
2. Check the brake fluid level; if low, add the recommended DOT fluid as specified in the owner's manual.
3. If the fluid is contaminated, consider a brake fluid flush.

5. Clear Trouble Codes

Sub-steps:
1. Use the OBD-II scanner to clear any stored ABS trouble codes after repairs.
2. Turn the ignition on (without starting the engine) and observe if the ABS light turns off.
