Solution

1. Preparation

Gather tools: multimeter, jumper cables, wrench set, screwdriver, and safety goggles.
Ensure the vehicle is in park (or neutral for manual transmissions) and the parking brake is engaged.

2. Battery Inspection and Maintenance

Disconnect the negative (-) terminal of the battery using a wrench to prevent electrical shorts.
Inspect the battery terminals for corrosion; if present, clean them using a wire brush.
Check the battery cables for damage; replace if frayed or broken.
Reconnect the battery terminals, starting with the positive (+) terminal first, followed by the negative (-).

3. Jump-Starting the Vehicle

Connect the jumper cables to the dead battery, red to positive (+) and black to negative (-).
Connect the other end of the jumper cables to a functioning vehicle, following the same positive and negative rules.
Start the functioning vehicle and let it run for a few minutes.
Attempt to start the Camry; if it starts, the issue may be a weak battery.

4. Starter Motor Testing

If the vehicle does not start after jump-starting, disconnect the battery again.
Locate the starter motor, usually found near the engine's transmission.
Using a wrench, connect a jumper wire directly to the starter motor's positive terminal from the battery.
Tap the starter lightly with a hammer; this may help if the internal components are stuck.
Reconnect the battery and attempt to start the vehicle.
