Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Replace or Repair ABS Module

Remove ABS Module:
- Locate the ABS module, usually mounted near the brake master cylinder.
- Disconnect the electrical connectors carefully.
- Unbolt the module from its mounting bracket using the appropriate socket.
Inspect the ABS Module:
- Check for moisture or corrosion on the connectors.
- If necessary, clean connectors with electrical contact cleaner.
Install New ABS Module (if replacement needed):
- Place the new ABS module in position, aligning it with the mounting holes.
- Secure it with bolts and tighten to the manufacturer’s specifications (typically around 7-10 Nm).
- Reconnect the electrical connectors ensuring they click into place.

3. Refill Brake Fluid

Check the brake fluid reservoir and refill with the appropriate type of brake fluid (usually DOT 3 or DOT 4).
Bleed the brake system to remove any air that may have entered during the ABS module replacement.

4. Reconnect Battery

Reconnect the negative terminal of the battery and ensure it is secured.

5. Clear Error Codes

Use the OBD-II scanner to clear any stored error codes related to the ABS system.
Perform a test drive to verify that the ABS warning light does not reappear.
