Solution

1. Preparation

Gather tools: multimeter, socket set, battery terminal cleaner, load tester, OBD-II scanner.
Ensure the vehicle is in "Park" or "Neutral" with the parking brake engaged.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Battery Replacement

Remove the negative battery terminal using a socket wrench.
Remove the positive battery terminal.
Unbolt the battery hold-down bracket and lift out the old battery.
Place the new battery in the tray and secure it with the hold-down bracket.
Connect the positive terminal first, followed by the negative terminal.

3. Starter Inspection/Replacement

Locate the starter motor (typically near the transmission).
Disconnect the electrical connectors from the starter.
Remove the mounting bolts securing the starter to the engine.
Carefully pull the starter out and replace it with a new unit.
Reconnect the electrical connectors and secure the starter with mounting bolts.

4. Final Checks

Reconnect the negative battery terminal.
Ensure all connections are tight and secure.
Perform a visual inspection for any loose wires or corroded connections.
