Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely parked with the engine off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Replace ABS Fuse

Locate the fuse box according to the owner's manual.
Remove the ABS fuse and check for continuity using a multimeter.
- Tools Required: Multimeter, fuse puller.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Check and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, add the correct type of brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Check for any signs of fluid leaks around the reservoir and brake lines.

4. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Inspect the sensor for dirt, damage, or loose connections.
Clean the sensor using electrical contact cleaner and reconnect it securely.

5. Test ABS Pump Operation

Reconnect the battery terminal.
Start the vehicle and activate the ABS by performing a controlled brake test in a safe area (avoid sudden stops).
Observe if the ABS light turns off after the test; if not, further diagnostics may be required.
