Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid electrical issues during repairs.

2. Check and Replace Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir and remove the cap.
2. Inspect the fluid level; if low, fill it with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
3. If the fluid is contaminated (dark or debris present), drain the system and replace with fresh fluid.

3. Inspect and Clean Wheel Speed Sensors

Tools Required: Ratchet and socket set, cleaning brush, and brake cleaner.
Sub-steps:
1. Remove the wheel corresponding to the illuminated ABS light.
2. Locate the wheel speed sensor; it is typically mounted near the brake rotor.
3. Disconnect the sensor harness and remove the sensor using the appropriate socket.
4. Clean the sensor and mounting area with brake cleaner, then re-install the sensor securely.
5. Reconnect the sensor harness.

4. Check ABS Module and Wiring

Sub-steps:
1. Inspect the wiring and connectors leading to the ABS module for signs of wear, corrosion, or damage.
2. Repair or replace any damaged wiring or connectors.
3. Ensure the ABS module is securely mounted and free from moisture.

5. Reconnect Battery and Clear Codes

Reconnect the vehicle's battery.
Use the OBD-II scanner to clear any existing ABS-related error codes.
Start the vehicle and check if the ABS light remains off.
