Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake cleaner.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery by removing the negative terminal.

2. Address Fault Codes

Sub-steps:
1. Connect the OBD-II scanner to the vehicle’s diagnostic port.
2. Retrieve and note any ABS-related fault codes.
3. Clear the codes and see if they return after a test drive.

3. Check Brake Fluid Level

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; if low, top off with the recommended brake fluid (DOT 3 or DOT 4, depending on model).
3. Inspect for leaks in brake lines or around the master cylinder.

4. Inspect ABS Components

Sub-steps:
1. Check the ABS fuses in the fuse box; replace any blown fuses.
2. Visually inspect the wheel speed sensors at each wheel for physical damage or connection issues.
3. Clean any dirt or debris from the sensors using brake cleaner.

5. Test Electrical Connections

Sub-steps:
1. Use a multimeter to test the battery voltage; it should be around 12.6 volts.
2. Check ground connections to the ABS module and battery for corrosion or loose connections.
3. Reconnect the battery once all checks are complete.

6. Reassemble and Test Drive

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the vehicle and check if the ABS light is still on.
3. Perform a test drive to ensure the ABS and traction control systems are functioning properly.
