Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace ABS Fuse

Locate the fuse box in the engine compartment or under the dashboard.
Remove the cover and identify the ABS fuse using the diagram on the fuse box cover.
Use a fuse puller or pliers to remove the fuse and inspect it.
- If blown: Replace it with a new fuse of the same amperage.

3. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Inspect the brake fluid level; it should be between the "MIN" and "MAX" marks.
- If low: Top off with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).

4. Inspect ABS Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors on each wheel hub.
Check for any dirt, debris, or physical damage to the sensors and wiring.
- If damaged: Disconnect the sensor connector and replace it with a new sensor.

5. Examine ABS Module and Wiring

Follow the wiring from the ABS module to each wheel speed sensor.
Look for any frayed wires or loose connections.
- If corrosion is found: Clean connections with electrical cleaner and reconnect securely.
- If wiring is damaged: Repair or replace the affected wiring.

6. Reconnect Battery and Reset ABS Light

Reconnect the battery terminals.
Use an OBD-II scanner to clear any stored ABS codes and reset the ABS light.
