Solution

1. Preparation

Tools Required: Multimeter, jumper cables, wire brush, safety gloves, safety goggles.
Safety Warnings: Ensure the vehicle is in "Park" or "Neutral" and the parking brake is engaged. Disconnect the battery before working on electrical connections.

2. Battery Voltage Check

Use a multimeter to measure the voltage at the battery terminals.
- If the voltage is below 12.4 volts, proceed to charge or replace the battery.

3. Clean Battery Terminals

Disconnect the battery terminals (negative first, then positive).
Use a wire brush to clean any corrosion from the battery terminals and cable ends.
Reconnect terminals securely, ensuring a tight fit.

4. Jump-Start the Vehicle

Connect jumper cables: positive to positive and negative to a suitable ground on the dead vehicle.
Start the donor vehicle and attempt to start the Corolla. If it starts, allow it to run for 15-20 minutes to charge the battery.

5. Inspect and Replace if Necessary

If the battery is unable to hold a charge after jump-starting, replace it with a new battery. Ensure the new battery matches the specifications for the Corolla E210.
