Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-step 1: Reconnect the battery terminals and check the voltage using a multimeter. If the voltage is low, charge the battery or replace it.
Sub-step 2: Clean the battery terminals with a wire brush to remove any corrosion.
Sub-step 3: Tighten the battery connections to ensure a solid connection.

3. Ignition System Check

Sub-step 1: Reconnect the battery and test the ignition switch by turning the key to the "Start" position.
Sub-step 2: If no voltage is detected at the starter solenoid, replace the ignition switch if necessary.

4. Starter and Wiring Inspection

Sub-step 1: Locate the starter motor and check the wiring connections for any loose or damaged wires.
Sub-step 2: If the connections are secure, use a multimeter to test the starter motor's functionality by applying 12 volts directly to the terminal. If it does not engage, replace the starter motor.
