my Toyota RAV4 Fifth Generation (2019-present) won't start just clicks what should I check

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is in "Park" (or "Neutral") with the parking brake engaged.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

• Sub-steps:
  • Use a multimeter to measure the battery voltage; it should read at least 12.4 volts.
  • If the battery is low, charge it using a battery charger or jump-start the vehicle.
  • Clean any corrosion on the battery terminals using a wire brush and a mixture of baking soda and water.

3. Starter Circuit Check

• Sub-steps:
  • Reconnect the battery terminal and turn the ignition key to the "Start" position while checking for voltage at the starter with a multimeter.
  • If voltage is present and the starter does not engage, proceed to remove the starter motor.
  • Remove the starter motor by disconnecting the electrical connectors and unbolting it from the engine block.

4. Starter Motor Testing

• Sub-steps:
  • Test the starter motor on a bench using a battery to see if it spins.
  • If it does not spin, replace the starter motor.
  • If it spins, reinstall the starter motor and ensure all connections are secure.

5. Reassembly

• Sub-steps:
  • Reconnect the battery terminal and secure it tightly.
  • Ensure all components are reinstalled correctly and no tools are left in the engine compartment.
  • Start the vehicle to confirm successful repair.
