Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and securely supported.
Disconnect the vehicle battery to prevent electrical shock.

2. Inspect and Remove ABS Module

Remove any components obstructing access to the ABS module (e.g., air intake duct).
Disconnect the electrical connector from the ABS module carefully.
Unbolt the ABS module using a socket set (typically 10mm or 12mm bolts).
Remove the ABS module from its mounting location.

3. Clean and Test the ABS Module

Inspect the ABS module for any physical damage or corrosion.
Clean the mounting surface and connectors with electrical contact cleaner.
If a replacement module is available, test the old module by bench testing it (if applicable) or proceed to install the new module.

4. Install New or Repaired ABS Module

Position the new or repaired ABS module in place and secure it with bolts, following the manufacturer’s torque specifications (typically around 7-10 ft-lbs).
Reconnect the electrical connector ensuring it clicks into place.
Reinstall any components removed during disassembly.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Turn the ignition to "ON" without starting the engine to check that the ABS warning light illuminates and then goes off after a few seconds.
Start the vehicle and check for proper ABS operation while driving.
