Solution

1. Preparation

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

2. Battery Check and Replacement

Sub-step 1: Reconnect the battery terminals and check the voltage with the multimeter.
Sub-step 2: If the voltage is low, jump-start the vehicle or replace the battery if it cannot hold a charge.
Sub-step 3: If a jump-start is successful, allow the battery to charge for at least 30 minutes before turning off the engine.

3. Starter Motor Inspection

Sub-step 1: Locate the starter motor beneath the vehicle, usually near the transmission.
Sub-step 2: Disconnect the electrical connectors and wiring from the starter.
Sub-step 3: Remove the starter motor from the engine by unscrewing the mounting bolts (usually requires a socket set).
Sub-step 4: Inspect the starter for any visible damage or wear, such as burnt components or excessive carbon buildup.

4. Replace Starter Motor (if necessary)

Sub-step 1: If the starter is damaged, install a new starter by reversing the removal steps.
Sub-step 2: Ensure all electrical connections are secure and clean.
Sub-step 3: Torque the mounting bolts to the manufacturer's specifications (typically around 15-20 lb-ft).

5. Reconnect Battery and Test

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the vehicle to ensure the repair was successful.
