Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, safety gloves.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Replacement

If the battery voltage is low:
1. Remove the battery:
  - Use a socket set to loosen and remove the battery terminal connections (negative first).
  - Unscrew any hold-down brackets securing the battery.
2. Install a new battery:
  - Place the new battery in the tray and secure it with brackets.
  - Reconnect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection

If the battery is functioning properly:
1. Remove the starter motor:
  - Disconnect any electrical connections to the starter motor.
  - Remove the mounting bolts using a socket set.
  - Carefully take the starter motor out of its mounting.
2. Inspect the starter motor for signs of wear or damage:
  - Check the gear and solenoid for proper operation.
3. Replace the starter motor if it is faulty:
  - Install the new starter motor by reversing the removal steps.
  - Ensure all electrical connections are secure.

4. Final Connections
