Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Scan and Resolve Error Codes

Use an OBD-II scanner to read the ABS-related error codes.
Note the codes and clear them after repairs are completed.

3. Inspect and Replace Components

A. Wheel Speed Sensors

Tools Required: Wrench set, multimeter
Disconnect the electrical connector from the wheel speed sensor.
Remove the sensor from the wheel hub using the appropriate socket.
Test the sensor with a multimeter to ensure it’s within specifications (typically 1,000-2,000 ohms).
If faulty, replace with a new sensor and reassemble.

B. Brake Fluid Check

Remove the brake fluid reservoir cap.
Inspect fluid level; if low, add the manufacturer-recommended fluid (DOT 3 or DOT 4).
If fluid is contaminated, perform a brake fluid flush.

C. ABS Control Module Inspection

Locate the ABS control module in the engine compartment or under the dashboard.
Check for loose wiring connections or corrosion.
If necessary, replace the module following the manufacturer's guidelines.

4. Reassembly and Final Checks

Reconnect the battery terminal.
Check all components for proper installation.
Clear any diagnostic codes from the system and perform a test drive.
