Solution

1. Preparation

Gather tools: Multimeter, socket set, torque wrench, jumper cables.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery for safety.

2. Battery Inspection

Sub-step 1: Inspect battery terminals. Clean off any corrosion using a wire brush and a solution of baking soda and water.
Sub-step 2: Tighten any loose terminal connections securely.
Sub-step 3: Reconnect the battery and check the voltage again with the multimeter.

3. Starter Relay Check

Sub-step 1: Locate the starter relay in the fuse box (refer to the owner’s manual for exact location).
Sub-step 2: Swap the starter relay with the identical relay to test functionality.
Sub-step 3: Attempt to start the vehicle again.

4. Starter and Wiring Inspection

Sub-step 1: If the vehicle still doesn’t start, visually inspect the wires leading to the starter motor for any signs of wear or damage.
Sub-step 2: Disconnect the starter motor wiring and check the connections.
Sub-step 3: If necessary, remove the starter motor for further inspection or testing.

5. Jump-Start Procedure (if applicable)

Sub-step 1: Connect jumper cables from a donor vehicle to the battery of the RAV4, ensuring proper polarity.
Sub-step 2: Start the donor vehicle and allow it to run for a few minutes.
Sub-step 3: Attempt to start the RAV4. If it starts, the battery may need replacement.
