Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (or neutral for manual transmissions) and the ignition is off.
Disconnect the negative battery terminal to avoid any electrical shorts.

2. Battery Replacement (if faulty)

Remove the positive battery terminal first, followed by the negative terminal.
Carefully remove the battery hold-down bracket using a socket set.
Lift the old battery out of the vehicle.
Place the new battery in the battery tray, ensuring it is secure.
Reinstall the battery hold-down bracket and tighten to manufacturer specifications (usually around 10-15 ft-lbs).
Connect the positive battery terminal first, followed by the negative terminal.

3. Starter Replacement (if starter motor is faulty)

Disconnect the negative battery terminal again.
Remove the intake air duct for access to the starter.
Disconnect the electrical connectors from the starter motor.
Remove the mounting bolts securing the starter to the engine block using a socket set.
Carefully extract the starter from its location.
Install the new starter by reversing the removal steps, ensuring all connections are secure and appropriately torqued.

4. Final Checks

Reconnect the negative battery terminal.
Start the vehicle to check if the issue is resolved.
Ensure there are no abnormal noises or issues during startup.
