Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in a safe location, on a flat surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Battery

Tools Required: Multimeter, wire brush, wrench set
Clean any corrosion from the battery terminals using a wire brush.
Tighten the battery terminals to ensure a good connection.
Reconnect the negative terminal and retest the battery voltage.

3. Jump-Start Procedure

Tools Required: Jumper cables
Connect the jumper cables: positive to positive and negative to a ground point on the dead vehicle.
Start the functioning vehicle and let it run for a few minutes.
Attempt to start the RAV4 again.

4. Check Starter Motor

Tools Required: Wrench set, screwdriver
If the vehicle still does not start, locate the starter motor.
Inspect wiring and connections to the starter for any damage.
Ensure that the starter is securely mounted and connections are tight.

5. Replace Battery or Starter (if necessary)

If the battery is found to be faulty (less than 12.4 volts), replace it with a new battery of the correct specifications.
If the starter motor is defective, remove the old starter:
- Disconnect wiring and mounting bolts.
