Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is turned off.
Gather necessary tools and parts.
Wear safety gloves and goggles.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and note any ABS-related trouble codes.
Clear the codes from the system and turn the ignition off.

3. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter.
Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from each sensor.
Use a multimeter to measure the resistance of each sensor (should be within manufacturer specifications).
If a sensor is faulty, remove the retaining bolt and carefully pull the sensor from the hub.
Install the new wheel speed sensor, securing it with the bolt to the specified torque.

4. Check and Replace ABS Fuse

Tools Required: Fuse puller or pliers.
Locate the fuse box under the dashboard or engine compartment.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity using a multimeter. Replace if blown.

5. Inspect and Top Off Brake Fluid

Tools Required: Brake fluid (DOT 3 or 4 as specified).
Open the hood and locate the master cylinder reservoir.
Check the fluid level; if low, add the appropriate brake fluid to the maximum line.
Inspect the reservoir cap for damage and ensure it is properly sealed.

6. Reconnect Battery and Test Drive

Reconnect the negative battery terminal if it was disconnected.
Start the vehicle and check if the ABS light is still illuminated.
Take the vehicle for a test drive to ensure proper braking performance and that the ABS light remains off.
