Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the transmission in 'Park' (automatic) or 'Neutral' (manual).
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Tools Required: Multimeter, socket set, battery terminal cleaner, wrench.
Inspect the battery terminals for corrosion; clean them using a battery terminal cleaner.
Check the battery voltage with a multimeter. If it's below 12.4 volts, proceed to replace the battery.
Remove the battery:
1. Disconnect the negative terminal first, then the positive terminal.
2. Remove any securing brackets and lift the battery out of the tray.
Install the new battery:
1. Place the new battery into the tray.
2. Connect the positive terminal first, then the negative terminal.
3. Secure any brackets or hold-downs.

3. Starter Motor Inspection and Replacement

Tools Required: Socket set, torque wrench, safety goggles.
Inspect the starter motor:
1. Locate the starter motor (usually found near the bottom of the engine near the transmission).
2. Check for loose connections and secure them if necessary.
3. If the starter motor is suspected to be faulty, remove it:
  - Disconnect the battery again (negative terminal).
  - Remove the electrical connections and bolts holding the starter in place.
4. Install a new starter motor:
  - Position the new starter into place and secure it with bolts.
  - Reconnect the electrical connections.
Reconnect the battery (positive terminal first, then negative).
