Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to avoid electrical shorts.

2. Inspect ABS Fuses

Locate the fuse box (refer to the vehicle's manual for location).
Remove the ABS fuse and check for continuity using a multimeter.
Replace the fuse if it is blown.

3. Check Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connectors and inspect for corrosion or damage.
Clean the sensor and connectors, and reconnect them securely.

4. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top it off with the recommended brake fluid (DOT 3 or DOT 4).
Inspect for any leaks in the brake lines or around the reservoir.

5. Inspect ABS Control Module Wiring

Trace the wiring from the ABS control module to the wheel speed sensors.
Look for any frayed wires, loose connections, or signs of wear.
Repair or replace any damaged wiring as necessary.

6. Reconnect Battery and Test Drive

Reconnect the battery terminals.
Start the vehicle and check if the ABS light is still illuminated.
Perform a test drive to confirm proper ABS function.
