Solution

1. Preparation

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

2. Inspect and Clean Battery Connections

Remove the positive (+) and negative (-) battery terminals.
Use a wire brush to clean the terminals and battery posts until shiny.
Reconnect the terminals, ensuring a snug fit.

3. Test and Replace the Battery (if necessary)

Use a multimeter to check the battery voltage again.
If the voltage is low, charge the battery or replace it if it holds less than 12.4 volts after charging.
Ensure the new battery is of the correct specifications (e.g., CCA rating) for the RAV4.

4. Test the Starter Motor

Locate the starter motor (typically underneath the vehicle near the transmission).
Use a jumper wire to connect the positive terminal of the battery to the starter solenoid terminal.
If the starter engages and the engine turns over, the starter may be faulty and should be replaced.

5. Reconnect Battery and Test

Reconnect the negative battery terminal securely.
Attempt to start the vehicle to verify if the problem is resolved.
