my Toyota RAV4 XA50 (2019-2024) won't start, just clicks, what should I do?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked in a safe location with the engine off and the key removed.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

• Sub-steps:
  1. Inspect battery terminals for corrosion; clean with a wire brush if necessary.
  2. If the battery voltage is low, jump-start the vehicle to see if it starts.
  3. If the battery is old (typically over 3-5 years), consider replacing it.
  4. Reconnect the terminals securely after cleaning or replacing the battery.

3. Starter Relay and Fuse Check

• Sub-steps:
  1. Locate the fuse box (usually under the dashboard or hood).
  2. Remove the starter relay and visually inspect it for damage.
  3. Replace the starter relay if it shows signs of wear or failure.
  4. Check the starter fuse and replace it if it is blown.

4. Starter Motor Inspection

• Sub-steps:
  1. Locate the starter motor, typically found near the transmission.
  2. Check the wiring harness connected to the starter for any damage or loose connections.
  3. If accessible, test the starter motor by applying direct battery voltage to it to see if it engages.
  4. If the starter does not engage, it may need to be replaced.
