Solution

1. Preparation

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

2. Inspect and Replace ABS Fuses

Locate the fuse box and identify the ABS fuses using the diagram on the cover.
Remove the ABS fuses using a fuse puller and inspect them for continuity.
Replace any blown fuses with new fuses of the same amperage rating.

3. Check and Clean ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensor area.
Disconnect the sensor connector and inspect the wiring for damage.
Clean the sensor with an appropriate electronic cleaner if necessary.
Reconnect the sensor and ensure it is securely fastened.

4. Check Brake Fluid Levels

Open the brake fluid reservoir cap and inspect the fluid level.
If low, top up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely after filling.

5. Inspect ABS Module and Wiring

Locate the ABS control module under the hood.
Check for corrosion or loose connections at the module and harness.
If damaged, consider replacing the ABS control module.

6. Reset ABS Light

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear any ABS fault codes and reset the ABS light.
Test drive the vehicle to ensure the ABS light does not reappear.
