Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Fill Brake Fluid

Locate the brake fluid reservoir (usually near the driver's side of the engine bay).
Inspect the fluid level; if low, clean the reservoir cap and remove it.
Add the recommended brake fluid (DOT 3 or DOT 4 as per owner’s manual) to the correct level.
Reinstall the cap securely.

3. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel (typically mounted near the brake rotor).
Remove the wheel for better access if necessary.
Clean the sensor area and check for dirt or debris.
Inspect the sensor and connector for damage; replace if needed.

4. Check Wiring and Connectors

Trace the wiring harness from the ABS wheel speed sensors to the ABS module.
Look for frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors.

5. Test ABS Pump Operation

Reconnect the negative battery terminal.
Start the vehicle and engage the brake pedal to check for normal operation.
Listen for the ABS pump activation sound when the brake pedal is pressed firmly.

6. Clear DTCs and Test Drive

Use the OBD-II scanner to clear any ABS-related diagnostic trouble codes.
Take the vehicle for a test drive to ensure the ABS light does not reappear and the system functions correctly.
