Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is in "Park" or "Neutral" and the parking brake is applied.
Disconnect the battery before starting any electrical work.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the negative terminal from the battery using a wrench.
2. Clean any corrosion from the terminals with a wire brush or terminal cleaner.
3. Reconnect the terminals securely.
4. If the battery is faulty, remove it from the vehicle and replace it with a new one of the same specifications (typically a Group 35 for the Camry).
5. Reinstall the new battery and connect the terminals securely.

3. Starter Relay and Wiring Check

Sub-steps:
1. Access the fuse box and locate the starter relay.
2. Swap the starter relay with a similar, functioning relay in the fuse box.
3. If the vehicle starts, replace the faulty relay.
4. If the issue persists, inspect the wiring leading to the starter; repair or replace any damaged or loose wires.

4. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor (typically near the bottom of the engine near the transmission).
2. Disconnect the electrical connectors from the starter.
3. Remove the starter motor mounting bolts using a socket set.
4. Remove the starter and bench test it or replace it if it fails to operate properly.
