Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Disconnect the sensor's electrical connector.
4. Remove the mounting bolts securing the sensor to the hub assembly.
5. Install the new wheel speed sensor and secure it with bolts.
6. Reconnect the sensor's electrical connector.
7. Repeat for all wheels if necessary.
Tools Required: Socket set, torque wrench, jack stands.
Safety Warnings: Ensure vehicle is securely supported before working under it.

3. Check and Replace ABS Module (if necessary)

Sub-steps:
1. Locate the ABS module, usually found near the brake master cylinder.
2. Disconnect the electrical connectors from the ABS module.
3. Remove the mounting bolts and detach the module from the vehicle.
4. Install the new ABS module and secure it with bolts.
5. Reconnect the electrical connectors.
Tools Required: Socket set, torque wrench.
Safety Warnings: Disconnect the battery before handling electronic components.

4. Refill Brake Fluid and Bleed the System

Sub-steps:
1. Check the brake fluid reservoir; refill with manufacturer-recommended brake fluid if low.
2. Bleed the brakes starting from the wheel farthest from the master cylinder (typically rear right).
3. Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve.
4. Repeat for all wheels.
Tools Required: Brake bleeder kit, wrench for bleeder screws.
Safety Warnings: Avoid spilling brake fluid, as it can damage vehicle paint.
