Solution

1. Preparation

Tools Required: Socket set, multimeter, jumper cables, safety gloves
Ensure the vehicle is in park and the ignition is off. Disconnect the negative battery terminal.

2. Battery Replacement (if battery is faulty)

Locate the battery in the engine compartment.
Using a socket set, remove the negative terminal first, followed by the positive terminal.
Remove the battery hold-down bracket and carefully lift the battery out.
Place the new battery in the tray and secure it with the hold-down bracket.
Connect the positive terminal first, then the negative terminal.

3. Starter Motor Replacement (if starter is faulty)

Locate the starter motor, usually near the transmission bell housing.
Disconnect the battery terminals to ensure safety.
Remove any electrical connectors from the starter.
Unbolt the starter from the engine using a socket set (note the mounting bolts' positions).
Carefully remove the starter from the vehicle.
Install the new starter by reversing the removal steps, ensuring all connections are secure, and torque the mounting bolts to manufacturer's specifications.
