Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wrench set.
Ensure the vehicle is in park (automatic transmission) or neutral (manual transmission).
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Remove the battery terminals (negative first, then positive).
Clean any corrosion from the terminals and battery posts using a wire brush.
Reconnect the battery terminals (positive first, then negative).

3. Jump-Start the Vehicle

Connect jumper cables to the dead battery and the working battery: positive to positive, negative to negative.
Start the working vehicle and let it run for a few minutes before attempting to start the RAV4.

4. Starter Motor Testing

Locate the starter motor and identify the solenoid terminal.
Reconnect the battery terminal and use a multimeter to check for voltage at the starter solenoid while someone turns the ignition key.
If voltage is present but the starter does not engage, replace the starter motor.

5. Ignition Switch Replacement (if necessary)

Remove the steering column covers using a screwdriver.
Disconnect the ignition switch wiring harness.
Remove screws securing the ignition switch and replace it with a new component.
Reconnect the wiring harness and reassemble the steering column.
