Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and set the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor area using a clean cloth.
If necessary, disconnect the sensor connector and clean the pins with electrical contact cleaner.
Reconnect the sensor and ensure it's securely fastened.

3. Replace ABS Fuse (if necessary)

Locate the fuse box (typically under the dashboard or hood).
Identify the ABS fuse using the fuse diagram on the cover.
Remove the fuse with a fuse puller or pliers.
Insert a new fuse of the same amperage and check for a secure fit.

4. Test and Replace ABS Module (if required)

Reconnect the battery and use a multimeter to check voltage at the ABS module connector.
If no voltage is detected, trace back to the wiring harness for issues.
If the ABS module is faulty, remove it by disconnecting the wiring and mounting bolts.
Install the new ABS module by reversing the removal process and ensuring all connections are secure.

5. Bleed Brake System

Use a brake bleeder kit to remove any air from the brake lines.
Start at the wheel furthest from the master cylinder and work towards the closest.
Continuously check the brake fluid level in the master cylinder during the process.
Ensure all brake lines are bled until clear fluid flows without bubbles.
