Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Battery Connections

Remove the negative cable from the battery.
Use a wire brush to clean the battery terminals and cable ends to ensure a good connection.
Reconnect the battery cable securely.

3. Test and Replace the Battery (if necessary)

Use a multimeter to check the voltage of the battery.
If the voltage is below 12.4 volts, charge the battery fully or replace it if it fails to hold a charge.
Ensure the battery is properly rated for the Camry model.

4. Check and Replace the Ignition Switch

Remove the steering column cover to access the ignition switch.
Disconnect the wiring harness from the ignition switch.
Test the ignition switch with a multimeter to ensure continuity when turned to the start position.
If defective, replace the ignition switch with a new one.

5. Inspect and Replace Starter Relay

Locate the fuse box and identify the starter relay.
Remove the relay and test it using a multimeter.
If faulty, replace it with a new relay.

6. Test Starter Motor

If the previous steps do not resolve the issue, ensure the starter motor is functioning.
Access the starter motor and check connections.
Use a jump wire to bypass the ignition switch and directly power the starter motor; if it engages, the starter is good, and the issue lies elsewhere.
