Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the vehicle's battery to ensure safety.

2. Scan and Record Error Codes

Use an OBD-II scanner to retrieve ABS-related error codes.
Document any codes for reference during repairs.
Clear the codes and see if they return after a short drive.

3. Inspect Wheel Speed Sensors

Remove the wheel corresponding to the ABS light.
Locate the wheel speed sensor on the hub assembly.
Clean any debris or dirt from the sensor and connector.
Check for proper sensor alignment and secure connections.

4. Check ABS Wiring and Module

Visually inspect the wiring harness connected to the ABS module for frays or breaks.
If accessible, check the ABS module for any signs of moisture or corrosion.
Use a multimeter to test continuity in the wiring to the sensors and module.

5. Brake Fluid Inspection

Open the master cylinder reservoir cap.
Check the brake fluid level and condition; replace if contaminated or low.
If fluid is contaminated, perform a brake fluid flush.

6. Test ABS Pump and Relay

Locate the ABS pump and relay.
Use a multimeter to check the relay operation; replace if faulty.
Activate the ABS pump (if applicable) to ensure it functions correctly.

7. Reassemble and Reconnect Battery
