Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter
Locate the wheel speed sensors at each wheel hub.
Sub-steps:
1. Remove the wheel to gain access to the sensor.
2. Disconnect the electrical connector for the wheel speed sensor.
3. Using a multimeter, check the sensor's resistance according to the manufacturer specifications.
4. If the resistance is out of spec, replace the wheel speed sensor.
5. Reconnect the sensor and the wheel, ensuring all connections are secure.

3. Check and Replace ABS Control Module

Tools Required: Socket set, torque wrench
Sub-steps:
1. Locate the ABS control module, usually found near the master cylinder.
2. Disconnect the electrical connectors from the ABS module.
3. Remove the mounting bolts securing the ABS module using a socket set.
4. Install the new ABS module and torque bolts to the manufacturer's specification.
5. Reconnect the electrical connectors to the ABS module.

4. Refill Brake Fluid and Bleed Brakes

Tools Required: Brake bleeder kit, wrench
Sub-steps:
1. Check and refill the brake fluid reservoir with the recommended brake fluid type.
2. Use a brake bleeder kit to bleed the brake lines, starting from the wheel furthest from the master cylinder.
3. Ensure there are no air bubbles in the brake fluid during the process.
4. Repeat for all wheels until the fluid runs clear and free of air.

5. Final Assembly and Testing

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light remains illuminated.
Test drive the vehicle to ensure brakes are functioning properly.
