Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, jumper cables.
Ensure the vehicle is in park (automatic) or neutral (manual), and the parking brake is engaged.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Sub-step 1: Reconnect the battery and use a multimeter to check voltage; if below 12.4 volts, consider charging or replacing the battery.
Sub-step 2: Clean battery terminals with a wire brush if corrosion is present.
Sub-step 3: If the battery is old or weak, replace it with a compatible 12V battery (check owner's manual for specifications).

3. Starter Motor Testing/Replacement

Sub-step 1: Locate the starter (usually near the transmission).
Sub-step 2: Disconnect the electrical connectors and mounting bolts.
Sub-step 3: Test the starter by applying direct power from the battery to the starter terminal.
Sub-step 4: If the starter does not engage, replace it with a new starter motor.

4. Ignition Switch and Wiring Inspection

Sub-step 1: Inspect the ignition switch for wear or failure signs.
Sub-step 2: If faulty, replace the ignition switch as per the manufacturer's instructions.
Sub-step 3: Check wiring harness leading to the starter for any damage or loose connections.
