Solution

1. Preparation

Tools Required: Multimeter, wrench set, socket set, hammer, OBD-II scanner
Disconnect the negative battery terminal to prevent electrical shock.
Gather all necessary tools and parts before starting.

2. Battery Replacement (if necessary)

Sub-steps:
1. Remove the negative terminal followed by the positive terminal from the battery.
2. Unbolt the battery hold-down clamp and carefully lift the battery out of the vehicle.
3. Place the new battery in the battery tray, ensuring it is secured properly.
4. Connect the positive terminal first, followed by the negative terminal.
5. Tighten the terminal connections securely to avoid any loose connections.

3. Starter Motor Inspection/Replacement

Sub-steps:
1. If the battery is good, locate the starter motor (usually found at the rear of the engine near the transmission).
2. Disconnect the electrical connections from the starter motor (note the orientation for reconnection).
3. Remove the mounting bolts securing the starter motor using a socket set.
4. Carefully pull the starter motor out from its mounting location.
5. Install the new or inspected starter motor by reversing the removal steps, ensuring all connections are secure.

4. Testing the System

Sub-steps:
1. Reconnect the negative battery terminal.
2. Attempt to start the vehicle to verify that the repair was successful.
3. If it starts, monitor for any unusual sounds or warning lights.
