Solution

1. Preparation

Tools Required: Multimeter, jumper cables, socket set, wrench set, and safety gloves.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean any corrosion from terminals and battery posts using a wire brush.
3. Reconnect the terminals securely, ensuring tight connections.

3. Jump-Start Procedure

Sub-steps:
1. Position a working vehicle close to the Camry, ensuring both vehicles are turned off.
2. Connect jumper cables: positive to positive terminal on both batteries, and negative to a clean metal ground on the Camry.
3. Start the working vehicle and let it run for a few minutes before attempting to start the Camry.

4. Starter Motor Testing

Sub-steps:
1. If the Camry still does not start, access the starter motor.
2. Disconnect the wiring harness from the starter and the battery cable.
3. Use a jumper wire to connect the starter's positive terminal directly to the battery.
4. If the starter engages and the engine cranks, the starter may need replacement.

5. Finalizing the Repair

If the battery was dead, replace it with a new battery if it fails the voltage test.
If the starter motor is faulty, replace it with a new unit according to manufacturer specifications.
