Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, brake cleaner, basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is turned off. Disconnect the battery to prevent electrical shock.

2. Replace Faulty Wheel Speed Sensor

Sub-steps:
1. Identify the faulty wheel speed sensor based on diagnostic trouble codes (DTC).
2. Raise the vehicle safely using jack stands and remove the corresponding wheel for access.
3. Disconnect the electrical connector from the wheel speed sensor.
4. Remove the sensor mounting bolt using a socket and ratchet.
5. Install the new wheel speed sensor by reversing the removal steps and torque the bolt to manufacturer specifications (typically around 7-10 Nm).
6. Reconnect the electrical connector ensuring a secure fit.

3. Repair or Replace ABS Module

Sub-steps:
1. If codes indicate ABS module failure, locate the ABS module (usually near the master cylinder).
2. Disconnect the battery again for safety.
3. Disconnect the wiring harness from the ABS module.
4. Remove the mounting bolts using a socket set and carefully detach the ABS module.
5. Install the new or refurbished ABS module, tightening bolts to the specified torque (usually around 10-12 Nm).
6. Reconnect the wiring harness and battery.

4. Bleed the Brake System

Sub-steps:
1. Use a brake bleeder kit or two-person method to bleed the brake lines.
2. Start from the wheel farthest from the master cylinder (usually the right rear) and proceed to the left rear, right front, and finally left front.
3. Ensure no air bubbles are present in the fluid until clear brake fluid runs out.

5. Clear Fault Codes

Sub-steps:
1. Reconnect the battery if it was disconnected.
2. Use the OBD-II scanner to clear any ABS fault codes present in the system.
3. Turn the ignition on without starting the engine and observe the ABS light for any re-illumination.
