Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace ABS Fuse

Locate the fuse box and identify the ABS fuse.
Remove the fuse using a fuse puller and visually inspect it.
Replace the fuse if it is blown with one of the same amperage.

3. Clean or Replace Wheel Speed Sensors

Raise the vehicle and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Clean the sensors with brake cleaner to remove any debris.
If damaged, remove the old sensor by unscrewing it and install a new one.

4. Check Brake Fluid Level and Lines

Open the hood and locate the brake fluid reservoir.
Check the fluid level; top off with the manufacturer's recommended brake fluid if low.
Inspect the brake lines for leaks or damage and replace any damaged lines.

5. Test ABS Module and Pump

Reconnect the battery.
Use a multimeter to check for power at the ABS module.
If the module is unresponsive, replace it according to manufacturer specifications.
