Solution

1. Preparation

Gather all required tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Scan for Codes

Use an OBD-II scanner to retrieve any stored ABS fault codes.
Note the codes for troubleshooting and repair reference.

3. Inspect and Replace Components

A. Check Fuses

Locate the fuse box and identify the ABS fuse.
Remove the fuse and inspect it. Replace if blown.
Reinstall the fuse and reconnect the battery.

B. Inspect Wheel Speed Sensors

Raise the vehicle and remove the wheels as necessary for access.
Visually inspect the sensors for damage or debris.
Clean the sensors with a soft cloth and replace if damaged.

C. Check Brake Fluid

Open the brake fluid reservoir and check the fluid level.
Top off with the correct type of brake fluid (DOT 3 or DOT 4 as specified).
Reconnect the battery and check if the ABS light turns off.

4. Test ABS System

Test drive the vehicle at low speeds to check for ABS operation.
If the ABS light remains on, the control module may need replacement.
