Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, wrench set, battery terminal cleaner, torque wrench, battery load tester.
Ensure the vehicle is in "Park" or "Neutral" and the parking brake is engaged.

2. Battery Replacement (if faulty)

Disconnect the negative battery terminal first, followed by the positive terminal.
Remove the battery hold-down bracket using the appropriate socket.
Carefully lift the old battery out of the tray.
Place the new battery in the tray and secure it with the hold-down bracket.
Reconnect the positive terminal first, then the negative terminal, ensuring they are tight.

3. Starter Motor Replacement (if faulty)

Disconnect the negative battery terminal to prevent electrical shock.
Remove any components obstructing access to the starter motor (this may include the air intake duct or exhaust heat shield).
Disconnect the electrical connectors from the starter motor and remove the mounting bolts using a socket.
Take out the old starter motor and install the new one in reverse order, ensuring proper alignment.
Reconnect all electrical connections and components that were removed.

4. Verification of Connections

Confirm all connections are secure and free from corrosion.
Reconnect the negative battery terminal.
Attempt to start the vehicle and check for any unusual sounds.
