Solution

1. Preparation

Tools Required: Wrench set, battery terminal cleaner, multimeter, safety goggles, gloves.
Ensure the vehicle is in park and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean Battery Terminals

Use a battery terminal cleaner to remove any corrosion from the battery terminals and cable ends.
Reconnect the cable ends securely to the battery posts.

3. Jump Start the Battery (if necessary)

Position a working vehicle nearby and connect jumper cables:
- Red clamp to dead battery positive terminal.
- Red clamp to working battery positive terminal.
- Black clamp to working battery negative terminal.
- Black clamp to an unpainted metal surface on the dead vehicle.
Start the working vehicle and then try to start the Camry.

4. Replace Battery (if necessary)

If the battery cannot hold a charge (below 12.4 volts after charging), it may need replacement.
Remove the old battery:
- Unfasten the battery hold-down clamp.
- Disconnect the negative terminal first, then the positive terminal.
- Lift the battery out carefully.
Install the new battery:
- Position the new battery in the tray.
- Connect the positive terminal first, followed by the negative terminal.
- Reinstall the hold-down clamp securely.

5. Check Charging System

Reconnect the negative battery terminal.
Start the vehicle and use a multimeter to check the alternator output.
Ensure readings are within the 13.8 to 14.2 volts range.
