Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, wire brush, and basic hand tools.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to prevent electrical shorts.

2. Scan for Error Codes

Use the OBD-II scanner to retrieve any ABS-related codes.
Document the codes and proceed to troubleshoot based on the specific code(s) retrieved.

3. Inspect ABS Fuse

Locate the fuse box (usually under the dashboard or hood).
Remove the ABS fuse and check for continuity using a multimeter.
Replace the fuse if it is blown and recheck the ABS light.

4. Check Wheel Speed Sensors

Raise the vehicle and securely support it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Inspect the sensors for physical damage or disconnection. Clean any dirt or debris.
Test the sensors with a multimeter to ensure they are functioning correctly.

5. Inspect ABS Control Module

Remove the panel covering the ABS control module.
Check for corrosion or damaged connectors.
If necessary, clean the connectors with a wire brush and electrical contact cleaner.
If the module is damaged, it may need to be replaced.

6. Verify Brake Fluid Level

Check the brake fluid reservoir for proper fluid level.
If the fluid is low, top it off with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect the fluid for contamination and replace it if necessary.

7. Reassemble and Test

Reconnect the battery after all checks and repairs are complete.
Clear any error codes using the OBD-II scanner.
Conduct a test drive to ensure the ABS light does not reappear and the system functions correctly.
