Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal for safety.

2. Inspect and Clean Battery Terminals

Remove the positive (+) and negative (-) battery cables from the battery terminals.
Clean the terminals and cable ends using a wire brush to remove any corrosion.
Reconnect the battery cables securely, ensuring no looseness.

3. Battery Replacement (if necessary)

If the battery voltage is low or the battery is over three years old, replace it.
Remove the old battery and install a new one, ensuring the positive cable is connected to the positive terminal and the negative cable to the negative terminal.
Use a battery with the same specifications (typically Group Size 35 for Corolla).

4. Starter Motor Testing or Replacement

If the battery is good, check the starter motor by using jumper cables to connect the starter directly to the battery.
If the starter engages and turns the engine, it may need to be replaced.
To replace, remove the starter mounting bolts using a socket set, disconnect the electrical connections, and replace it with a new starter, ensuring all connections are secure.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Attempt to start the vehicle to verify if the issue is resolved.
