Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and disconnect the negative battery terminal to ensure safety during repairs.

2. Address Fault Codes

Sub-step 1: Use the OBD-II scanner to clear any fault codes.
Sub-step 2: Reconnect the battery terminal and start the vehicle to see if the ABS light remains illuminated.

3. Inspect and Replace Sensors

Sub-step 1: If fault codes indicate a specific wheel speed sensor failure, remove the wheel corresponding to the faulty sensor.
Sub-step 2: Disconnect the sensor harness and remove the old sensor from its mounting location.
Sub-step 3: Install the new sensor and secure it in place. Reconnect the harness.
Tools Required: Socket set, ratchet, torque wrench.

4. Check and Replace Brake Fluid

Sub-step 1: If the brake fluid is low or contaminated, drain the old brake fluid from the master cylinder.
Sub-step 2: Refill with fresh brake fluid that meets the manufacturer's specifications (DOT 3 or DOT 4).
Sub-step 3: Bleed the brake system to remove any air from the lines.
Tools Required: Brake fluid, turkey baster, brake bleeder kit.

5. Inspect and Replace Fuses/Relays

Sub-step 1: Locate the fuse box, typically found under the dashboard or in the engine compartment.
Sub-step 2: Identify the ABS fuse and relay, then inspect them for continuity. Replace if necessary.
Tools Required: Fuse puller or needle-nose pliers.
