Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools, brake fluid.
Ensure the vehicle is parked on a flat surface and the ignition is off before starting work.

2. Inspect and Replace ABS Fuse

Locate the fuse box (usually under the dashboard or engine compartment).
Using the fuse puller or pliers, remove the ABS fuse.
Inspect the fuse for any signs of damage (burnt or broken).
If damaged, replace it with a fuse of the same amperage.
Reinsert the fuse and check for proper operation.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Remove the cap and check the fluid level; it should be between the 'MIN' and 'MAX' marks.
If low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
Inspect for any leaks in brake lines, hoses, and connections.

4. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors (typically near each wheel assembly).
Visually inspect for any physical damage, dirt, or debris.
Disconnect the sensor connector and use a multimeter to check for proper resistance (usually within manufacturer specifications).
If the sensor is faulty, replace it with a new one.

5. Test and Replace Brake Pedal Switch

Locate the brake pedal switch, typically mounted near the top of the brake pedal.
Use a multimeter to check for continuity when the brake pedal is pressed.
If there's no continuity, replace the brake pedal switch with a new one.

6. Clear Error Codes

After making repairs, use an OBD-II scanner to clear any stored ABS error codes.
Perform a test drive to ensure the ABS light does not illuminate again.
