Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid.
Safety Warnings: Ensure the vehicle is on a level surface and secured with wheel chocks.

2. Replace ABS Fuse

Locate the fuse box (refer to the owner's manual for the exact location).
Use a fuse puller or pliers to remove the ABS fuse.
Inspect the fuse for any signs of damage; replace it if blown.
Reinstall the new fuse and close the fuse box.

3. Check and Top Off Brake Fluid

Open the hood and locate the master cylinder reservoir.
Inspect the brake fluid level; if low, add the recommended type of brake fluid (usually DOT 3 or DOT 4).
Close the reservoir cap securely.

4. Inspect Wheel Speed Sensors

Lift the vehicle using appropriate jack stands.
Locate the wheel speed sensors on each wheel hub.
Inspect wiring for damage or disconnections.
If necessary, disconnect the sensor and measure resistance with a multimeter (should typically be within the manufacturer's specified range).
Replace any faulty sensors.

5. Inspect ABS Module Connections

Locate the ABS module, usually near the master cylinder.
Disconnect the electrical connector carefully.
Inspect for corrosion or bent pins; clean connectors if necessary.
Reconnect the module ensuring a secure fit.

6. Clear Error Codes

Reconnect the OBD-II scanner to the vehicle.
Navigate to the ABS section and clear any stored error codes.
Turn the ignition off and then back on to check if the ABS light has turned off.
