Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on the electrical system.

2. Replace Faulty Wheel Speed Sensor

Tools Required: Socket set, torque wrench, multimeter
Sub-steps:
1. Raise the vehicle securely on jack stands and remove the wheel to access the wheel speed sensor.
2. Disconnect the electrical connector from the faulty wheel speed sensor.
3. Remove the sensor using the appropriate socket or wrench.
4. Install the new wheel speed sensor and torque it to the manufacturer’s specifications (refer to service manual for exact torque values).
5. Reconnect the electrical connector.

3. Replace ABS Module (if necessary)

Tools Required: Socket set, torque wrench, brake line wrench
Sub-steps:
1. Disconnect the battery and the wiring harness from the ABS module.
2. Remove the brake lines connected to the ABS module (use a brake line wrench to avoid rounding the fittings).
3. Unbolt the ABS module from its mounting bracket.
4. Install the new ABS module and torque it to specifications.
5. Reattach the brake lines and ensure there are no leaks.
6. Reconnect the wiring harness and the battery.

4. Bleed Brake System

Tools Required: Brake bleeder kit, brake fluid
Sub-steps:
1. Fill the brake fluid reservoir with the appropriate type of brake fluid.
2. Bleed the brake system to remove any air bubbles, starting from the wheel farthest from the master cylinder.
3. Repeat the bleeding process for all wheels until no air is present.
