Solution

1. Preparation

Gather tools: multimeter, socket set, torque wrench, and a hammer.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Inspect the battery for any physical damage or bulging.
2. Clean any corrosion from battery terminals and cable ends using a wire brush.
3. Reconnect the battery terminals securely.
4. If the battery is weak or dead, replace it with a new one, ensuring it matches the specifications for the RAV4.

3. Starter Motor Replacement (if necessary)

Sub-steps:
1. Remove the battery terminals, starting with the negative, then the positive.
2. Disconnect the wiring harness from the starter motor.
3. Remove the mounting bolts (typically 2-3) securing the starter motor to the engine.
4. Carefully extract the starter motor from its location.
5. Install the new starter motor by reversing the removal steps, ensuring all connections are secure.
6. Torque the mounting bolts to the manufacturer's specifications (usually around 10-15 ft-lbs).

4. Reconnect Battery and Test

Sub-steps:
1. Reconnect the positive battery terminal first, followed by the negative terminal.
2. Start the vehicle to ensure the repair was successful.
