Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the negative terminal of the battery.

2. Inspect ABS Components

Sub-step 1: Locate the ABS module and inspect for physical damage or leaks.
Sub-step 2: Clean any dirt around the ABS wheel speed sensors with a soft cloth.
Sub-step 3: Remove the wheel to access the wheel speed sensors and check for proper alignment and mounting.

3. Replace Faulty Components

Sub-step 1: If the ABS wheel speed sensor is faulty, remove the sensor by unscrewing it from the hub assembly (usually requires a socket wrench).
Sub-step 2: Install the new wheel speed sensor and torque it to the manufacturer’s specifications (typically around 7-10 Nm).
Sub-step 3: If necessary, replace the ABS module by disconnecting the wiring harness, removing mounting bolts, and installing the new module.

4. Reassemble and Reconnect

Sub-step 1: Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (usually around 100-120 Nm).
Sub-step 2: Reconnect the negative battery terminal.
Sub-step 3: Start the vehicle and check for ABS light status.
