Solution

1. Preparation

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

2. Inspect Brake Fluid

Locate the master cylinder reservoir.
Remove the cap and check the fluid level; top off with the recommended brake fluid (DOT 3 or DOT 4).
If fluid is contaminated, consider flushing the brake system.

3. Check ABS Sensors

Lift the vehicle safely using jack stands.
Remove the wheel to access the brake components.
Inspect the wheel speed sensors for debris or damage; clean or replace as necessary.
Measure resistance across each sensor using a multimeter; compare readings to manufacturer specifications.

4. ABS Module Inspection

Reconnect the battery.
Using the OBD-II scanner, clear any existing ABS fault codes.
Perform a test drive to see if the ABS light reappears.
If the light returns, inspect the ABS module for faults; consider replacement if necessary.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Conduct a function test of the brakes to ensure proper operation.
Monitor the ABS light during the test drive to confirm the issue is resolved.
