Solution

1. Preparation

Gather tools: Multimeter, socket set, wrenches, OBD-II scanner, jumper cables.
Ensure the vehicle is in a safe, well-ventilated area with the engine off.

2. Battery Inspection

Sub-step 1: Disconnect the negative battery terminal to prevent electrical shorts.
Sub-step 2: Clean any corrosion from the battery terminals using a wire brush.
Sub-step 3: Check battery voltage with a multimeter; replace if below 12.4 volts.

3. Starter Motor Replacement (if tested faulty)

Sub-step 1: Disconnect the negative battery terminal again for safety.
Sub-step 2: Remove any components obstructing access to the starter motor (such as the air intake duct).
Sub-step 3: Unplug the electrical connectors from the starter motor.
Sub-step 4: Remove the starter motor mounting bolts using a socket set.
Sub-step 5: Replace with a new starter motor, tightening bolts to the manufacturer's specified torque (typically around 20-25 Nm).
Sub-step 6: Reconnect electrical connectors and any removed components.

4. Ignition Switch Replacement (if tested faulty)

Sub-step 1: Remove the steering column cover using a screwdriver.
Sub-step 2: Disconnect the wiring harness from the ignition switch.
