Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery cable to avoid any electrical shorts.

2. Battery Inspection

Sub-steps:
1. Visually inspect the battery for any signs of swelling or leaks.
2. Clean battery terminals using a wire brush and a mixture of baking soda and water to remove corrosion.
3. Reconnect the battery terminals securely.

3. Jump Start Procedure

Sub-steps:
1. Use jumper cables to connect the dead battery to a functioning vehicle (red to positive, black to ground).
2. Allow the working vehicle to run for a few minutes before attempting to start the Corolla.
3. If the vehicle starts, allow it to run and check the battery voltage.

4. Starter Motor Replacement (if necessary)

Sub-steps:
1. Remove any components obstructing access to the starter motor (e.g., air intake tube).
2. Disconnect the wiring harness from the starter and remove the mounting bolts using a socket set.
3. Remove the old starter motor and replace it with a new one.
4. Reconnect the wiring harness and tighten mounting bolts to the manufacturer's torque specifications (typically around 15-20 ft-lbs).
5. Reinstall any removed components.
