Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Diagnose and Clear Codes

Connect an OBD-II scanner to the vehicle’s diagnostic port.
Read and record any ABS-related trouble codes.
Clear the codes from the system and see if the ABS light returns after a short test drive.

3. Inspect ABS Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel of the affected axle to access the ABS sensor.
Check the sensor for dirt accumulation or damage.
Clean the sensor with appropriate brake cleaner and reattach it securely.
Repeat this process for all four wheels.

4. Check Brake Fluid

Inspect the brake fluid reservoir located near the master cylinder.
If the fluid is low, top it up with the recommended brake fluid type (usually DOT 3 or DOT 4).
If the fluid appears contaminated, consider flushing the brake system.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the ABS module and sensors.
Look for fraying, corrosion, or any physical damage.
Repair or replace any damaged wiring or connectors.

6. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle and monitor the ABS warning light.
Test the brakes at low speed to ensure proper operation.
