Solution

1. Preparation

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

2. Inspect and Clean ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors on each wheel hub.
Remove any dirt or debris around the sensors using a clean cloth.
If applicable, disconnect the sensor wiring harness and inspect for damage.
Reconnect the sensor and secure any loose wiring.

3. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Remove the cap and visually inspect the brake fluid level.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner’s manual).
Reinstall the cap securely after topping off.

4. Replace Blown ABS Fuse

Locate the fuse box and find the ABS fuse (refer to the owner’s manual for the exact location).
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.

5. Test ABS Pump and Module

Connect the negative battery terminal.
Start the vehicle and observe the ABS light; it should turn off after a few seconds.
If it remains on, use a multimeter to check the voltage at the ABS module connectors.
Follow the service manual for specific voltage and resistance specifications.
