Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to avoid electrical shorts during repairs.
Ensure the vehicle is on a flat surface and securely lifted if necessary.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read and note any ABS error codes.
Clear the codes to see if the light returns after the system is reset.

3. Inspect Wheel Speed Sensors

Remove the wheel covering the ABS sensor.
Locate the ABS wheel speed sensor and disconnect the electrical connector.
Clean the sensor and inspect for physical damage or debris.
Reconnect the sensor and ensure it is secure.

4. Check ABS Fuse

Locate the fuse box and identify the ABS fuse using the diagram on the cover.
Remove the fuse and inspect it for continuity using a multimeter.
Replace with a new fuse if it is blown.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the ABS module and wheel speed sensors for frays or corrosion.
Repair or replace damaged wiring or connectors.

6. Brake Fluid Check

Inspect the brake fluid reservoir for proper fluid level.
If low, top up with manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
If the fluid is contaminated, perform a brake fluid flush.
