Solution

1. Preparation

Gather necessary tools and parts before starting.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-steps:
- Remove the negative terminal followed by the positive terminal from the battery.
- Clean battery terminals using a wire brush to remove corrosion.
- Reconnect the battery terminals, positive first, then negative.
Tools Required: Wire brush, socket set.

3. Replace the Battery (if necessary)

Sub-steps:
- If the battery voltage is below 12.4 volts or the battery is old (over 3-5 years), replace it.
- Remove the battery hold-down bracket using a socket wrench.
- Carefully lift the 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.
Tools Required: Socket set, battery terminal cleaner.

4. Starter Inspection

Sub-steps:
- If the battery is fine, locate the starter motor (usually under the vehicle near the transmission).
- Remove electrical connections to the starter solenoid.
- Test the starter motor by applying 12 volts directly to the solenoid terminal using jumper wires.
- If the starter does not engage, replace the starter motor.
Tools Required: Socket set, jumper wires, multimeter.

5. Reassemble and Final Checks

Sub-steps:
- Reconnect all electrical connections.
- Ensure all tools are removed from the engine bay.
- Reconnect the negative battery terminal.
Tools Required: None additional.
