Solution
1. Preparation
  • Tools Required: OBD-II scanner, multimeter, jumper cables, socket set.
  • Disconnect the negative battery terminal to ensure safety while working on electrical components.
2. Battery Inspection and Replacement
  • Remove the battery terminals (negative first, then positive) using a socket set.
  • Inspect the battery for any signs of damage or swelling.
  • If the battery voltage is low (below 12.4 volts), charge the battery using a battery charger or replace it if defective.
  • Reinstall the battery terminals securely, ensuring good contact.
3. Starter Motor Testing and Replacement
  • Locate the starter motor beneath the vehicle, usually near the engine block.
  • Disconnect the wiring harness and the battery cable from the starter motor.
  • Remove the starter motor by unscrewing the mounting bolts with a socket set.
  • Test the starter motor by connecting it directly to the battery; if it does not engage, replace with a new starter.
  • Install the new starter by reversing the removal steps, ensuring all connections are secure.
4. Final Assembly
  • Reconnect the battery terminals (positive first, then negative).
  • Ensure all tools are removed from the engine bay.
  • Reconnect any other components that may have been removed for access.
