Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is in a safe, well-ventilated area with appropriate lighting.

2. Inspect the ABS Module

Sub-step 1: Locate the ABS module, typically found near the master cylinder on the driver's side.
Sub-step 2: Check for any visible leaks around the module and inspect the mounting bolts for tightness.
Sub-step 3: Remove the connectors from the ABS module by pressing the release tabs and gently pulling them off.

3. Test the ABS Module

Sub-step 1: Using a multimeter, check the power supply to the ABS module. Connect the multimeter probes to the power and ground terminals of the module. It should read around 12 volts.
Sub-step 2: If the voltage is correct, reconnect the ABS module connectors.
Sub-step 3: Use the OBD-II scanner to perform an ABS activation test if available, ensuring the module responds appropriately.

4. Replace or Repair (if necessary)

Sub-step 1: If the ABS module is faulty, remove it by unscrewing the mounting bolts using a socket set.
Sub-step 2: Install the new ABS module, ensuring it is seated properly and tighten the bolts to manufacturer's torque specifications (usually around 10-15 Nm).
Sub-step 3: Reconnect the ABS module connectors and any other components that were removed.
