Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Check and Replace ABS Fuse

Sub-steps:
- Locate the fuse box, typically found under the dashboard or in the engine bay.
- Use a fuse puller to remove the ABS fuse and check for continuity with a multimeter.
- If the fuse is blown, replace it with one of the same amperage.
Tools Required: Fuse puller, multimeter
Safety Warnings: Ensure the ignition is off before working on electrical components.

3. Inspect and Clean Wheel Speed Sensors

Sub-steps:
- Raise the vehicle using a jack and secure it on jack stands.
- Remove the wheel to access the wheel speed sensors.
- Inspect the sensors for dirt, debris, or damage.
- Clean the sensors with a soft cloth and electrical contact cleaner if necessary.
- Reinstall the wheel and lower the vehicle.
Tools Required: Jack, jack stands, socket set, soft cloth, electrical contact cleaner
Safety Warnings: Always use jack stands to support the vehicle securely.

4. Check Brake Fluid Level

Sub-steps:
- Open the master cylinder reservoir cap carefully.
- Inspect the fluid level; it should be between the minimum and maximum marks.
- If low, top up with the recommended brake fluid type (usually DOT 4).
Tools Required: Brake fluid
Safety Warnings: Do not spill brake fluid on painted surfaces as it can cause damage.

5. Clear Fault Codes

Sub-steps:
- Reconnect the OBD-II scanner to the vehicle.
- Navigate to the ABS module and clear any stored fault codes.
- Turn the ignition on to check if the ABS light has turned off.
Tools Required: OBD-II scanner
