Solution

1. Preparation

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

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter
Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Disconnect the electrical connector from the sensor.
3. Remove the retaining bolt with a socket and carefully pull the sensor out.
4. Test the sensor using a multimeter to ensure proper resistance (typically 1,000-2,000 ohms).
5. If faulty, install the new wheel speed sensor by reversing the removal steps and torque the bolt to manufacturer's specifications.

3. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Check the fluid level; if low, refill with the appropriate DOT fluid as specified in the owner's manual.
3. Inspect for any visible leaks in brake lines or around the master cylinder.

4. Inspect ABS Module and Wiring

Tools Required: OBD-II scanner, socket set
Sub-steps:
1. Reconnect the negative battery terminal.
2. Use an OBD-II scanner to check for ABS-related codes.
3. If codes indicate a fault in the ABS module, inspect wiring for frays or corrosion.
4. Replace any damaged wiring and connectors as necessary.
