Solution

1. Preparation

Gather tools: Multimeter, jumper cables, socket set, wrench set, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and set the parking brake.

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery using a wrench.
Sub-step 2: Clean any corrosion on the battery terminals with a wire brush.
Sub-step 3: Reconnect the terminals securely, starting with the positive terminal first.

3. Jump-Starting the Vehicle

Sub-step 1: Position a working vehicle close to the RAV4 and connect jumper cables: positive to positive and negative to negative.
Sub-step 2: Start the working vehicle and let it run for a few minutes before attempting to start the RAV4.
Sub-step 3: If the RAV4 starts, allow it to run to charge the battery.

4. Starter Motor Testing

Sub-step 1: Locate the starter motor (typically near the engine and transmission junction).
Sub-step 2: Disconnect the wiring harness from the starter motor.
Sub-step 3: Use jumper cables to apply 12 volts directly to the starter motor's terminal.
Sub-step 4: If the starter engages and the engine cranks, the starter motor is functional, and further investigation into other issues may be needed.

5. Replacing Faulty Components

If the battery is faulty and fails to hold a charge, replace it with a new battery of the same specifications (typically a group size 24F for RAV4).
If the starter is defective, remove it using the socket set, replace it with a new starter motor, and reconnect the wiring.
