Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shock while working on the ABS system.

2. Scan and Clear Codes

Use an OBD-II scanner to retrieve ABS-related codes.
Document any codes displayed.
Clear the codes using the scanner to reset the ABS system.

3. Inspect Wheel Speed Sensors

Locate each wheel speed sensor near the brake rotor.
Remove any debris or dirt from the sensor area.
Disconnect the electrical connector and inspect for corrosion or damage.
Reconnect the sensor and ensure it is securely attached.

4. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
Inspect the fluid for contamination; replace if necessary.

5. Inspect ABS Module and Wiring

Locate the ABS module (typically near the master cylinder).
Check for visible damage or loose connections on the module and wiring harness.
If necessary, use a multimeter to test the module's power and ground connections.

6. Reconnect Battery and Test Drive

Reconnect the battery terminals.
Start the vehicle and perform a test drive to check if the ABS light remains off.
