Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical short circuits.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect ABS Sensors

Tools Required: Multimeter, screwdriver set
Remove the wheel covers or tires to access the wheel speed sensors.
Disconnect the sensor connector and check the resistance with a multimeter (specification typically between 800-1200 ohms).
If the sensor is out of range, replace the sensor.

3. Check ABS Modules

Tools Required: OBD-II scanner
Reconnect the battery and use the OBD-II scanner to clear any existing codes.
If the ABS light remains on, access the ABS module and inspect for any visible issues such as burn marks or loose connections.
Replace the ABS module if necessary.

4. Brake Fluid Inspection

Tools Required: Brake fluid tester (optional)
Check the brake fluid level; top off with the recommended DOT fluid if low.
Inspect the fluid condition; if contaminated, flush the brake system and replace with new fluid.

5. Reassemble and Test

Reinstall wheels and any removed components.
Reconnect the battery and perform a test drive to ensure the ABS light is off and the system is functioning correctly.
