Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool down if it has been running recently.

2. Battery Inspection

Sub-steps:
1. Remove the positive (+) and negative (-) battery terminals.
2. Inspect the battery for any signs of damage or swelling.
3. Clean the battery terminals and posts with a wire brush and a mixture of baking soda and water if corrosion is present.
4. Reconnect the battery terminals securely.

3. Starter Motor Test

Sub-steps:
1. Locate the starter motor (typically near the transmission).
2. Check the wiring harness connected to the starter for any damage or loose connections.
3. Use a multimeter to test for voltage at the starter solenoid when the ignition is turned to the start position.
4. If there is voltage but the starter doesn't engage, replace the starter motor.

4. Jump Start Procedure (if necessary)

Sub-steps:
1. Gather jumper cables and another vehicle with a functioning battery.
2. Connect the positive (+) terminal of the dead battery to the positive terminal of the good battery.
3. Connect the negative (-) terminal of the good battery to a metal ground on the dead vehicle (do not connect directly to the negative terminal).
4. Start the working vehicle, wait a few minutes, then attempt to start the RAV4.
