Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical shocks.

2. Inspect and Replace ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Use a socket set to remove the sensor mounting bolts.
Inspect the sensor for damage or dirt; clean or replace as necessary.
Reinstall the new sensor and torque the bolts to manufacturer specifications.

3. Check and Replace the ABS Fuse

Locate the fuse box (refer to the owner’s manual for its location).
Remove the ABS fuse and inspect it for continuity.
If blown, replace it with a new fuse of the same amperage.

4. Inspect Brake Fluid Level

Open the hood and check the brake fluid reservoir.
If the fluid is low, top it off with the appropriate brake fluid type (usually DOT 3 or DOT 4).
Inspect for any leaks in the brake lines.

5. Test the ABS Control Module

Reconnect the battery.
Use a scan tool to clear any ABS trouble codes and perform a self-test of the ABS system.
If the light remains on, the ABS control module may need to be replaced.
