Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Scan and Clear Codes

Tool Required: OBD-II scanner
Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve any stored ABS fault codes.
Clear the codes and see if the ABS light returns after a short drive.

3. Inspect ABS Fuse

Locate the fuse box (refer to the owner’s manual for location).
Remove the ABS fuse using a fuse puller.
Inspect the fuse; if it is blown, replace it with a fuse of the same amperage.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; it should be between the minimum and maximum marks.
If low, add the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).

5. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensors.
Check the wiring for damage or disconnections.

6. Test ABS Control Module

Reconnect the battery terminal.
Use a multimeter to check for voltage at the ABS control module.
Ensure that the ground connections are secure and free from corrosion.
