Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve any stored ABS trouble codes and make note of them.
Clear the codes and start the vehicle to check if the ABS light returns.

3. Inspect ABS Sensors

Remove the wheel corresponding to the ABS warning light.
Locate the ABS wheel speed sensor; disconnect the wiring harness.
Using a multimeter, measure the resistance across the sensor terminals; it should typically be between 1,000 to 2,000 ohms.
If out of range, replace the sensor.

4. Check ABS Module

Inspect the ABS control module for any signs of physical damage or corrosion at the connectors.
If necessary, disconnect the module and clean the contacts with electrical cleaner.
Reconnect the module and ensure all connections are secure.

5. Brake Fluid Inspection

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top off with the recommended brake fluid (usually DOT 3 or DOT 4).
Inspect the fluid for contamination; if dirty, a brake fluid flush may be necessary.

6. Reassemble and Reconnect

Reinstall the wheel and secure it properly.
Reconnect the negative battery terminal.
Perform a test drive to ensure the ABS light is no longer illuminated and the system is functioning correctly.
