Solution

1. Preparation

Tools required: OBD-II scanner, multimeter, socket set, brake fluid, and basic hand tools.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace ABS Wheel Speed Sensors

Sub-step 1: Locate the ABS wheel speed sensors at each wheel. Use the socket set to remove the sensor mounting bolts.
Sub-step 2: Disconnect the electrical connector for the sensor and remove it from the wheel hub.
Sub-step 3: Clean the mounting area and ensure no debris is present before installing the new sensor.
Sub-step 4: Install the new sensor by reversing the removal steps and securing it with the proper torque (typically around 10 Nm).
Sub-step 5: Reconnect the electrical connector securely.

3. Check and Replace ABS Control Module

Sub-step 1: Remove the cover of the ABS control module, which is usually located near the brake master cylinder.
Sub-step 2: Inspect the module for any visible damage or corrosion on connectors.
Sub-step 3: If the module is faulty, disconnect the battery again and remove the control module by unplugging the connectors and unscrewing any mounting bolts.
Sub-step 4: Install the new ABS control module by reversing the removal steps and reconnecting all electrical connectors.
Sub-step 5: Reconnect the battery and reset the system with an OBD-II scanner.
