Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench
Sub-steps:
1. Remove the wheel corresponding to the faulty sensor as indicated by the diagnostic codes.
2. Unplug the electrical connector from the wheel speed sensor.
3. Remove the sensor from its mounting location.
4. Inspect the sensor for damage or corrosion, and replace if necessary.
5. Install the new sensor, ensuring it is secured properly and the connector is firmly attached.

3. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
3. If low, add the appropriate brake fluid type as specified in the owner's manual.
4. Replace the cap securely after refilling.

4. Inspect ABS Module and Wiring

Tools Required: Visual inspection tools
Sub-steps:
1. Locate the ABS module, typically near the brake master cylinder.
2. Check for any loose or damaged wiring connected to the module.
3. If any damage is found, repair or replace the wiring as necessary.
4. Reconnect the battery and clear any diagnostic codes.
