Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Scan for Error Codes

Use an OBD-II scanner to connect to the vehicle's diagnostic port.
Record any error codes related to the ABS system for further troubleshooting.

3. Inspect ABS Sensors

Remove the wheel (using a jack and jack stands).
Locate the ABS sensor on each wheel hub.
Clean any debris or dirt from the sensor area and check the wiring for damage.
If damaged, replace the ABS sensor with a new one.

4. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated (dark or has particles), perform a brake fluid flush.

5. Examine ABS Control Module

Inspect the ABS control module connections for corrosion or loose wires.
If necessary, replace the ABS control module according to manufacturer specifications.

6. Test the Brake Light Switch

Locate the brake light switch beneath the dashboard.
Use a multimeter to test the switch for continuity while engaging the brake pedal.
Replace the brake light switch if it fails the continuity test.
