Solution

1. Preparation

Tools Required:
- Multimeter
- Socket set
- Torque wrench
- Battery terminal cleaner
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Remove Battery Terminals: Using a socket wrench, remove the negative (-) terminal first followed by the positive (+) terminal.
Clean Battery Terminals: Use a battery terminal cleaner or a wire brush to clean any corrosion from the battery terminals and cable ends.
Test Battery: If the battery fails the load test, replace it with a new battery of the same specifications (typically Group 35 or 24F for RAV4).
Reinstall Battery: Connect the positive (+) terminal first, then the negative (-) terminal. Ensure connections are tight.

3. Starter Motor Inspection and Replacement

Locate Starter Motor: The starter is located near the engine block, typically on the driver's side.
Remove Starter: Disconnect the electrical connectors and remove the mounting bolts using a socket set.
Inspect Starter: Check for signs of wear or damage. If faulty, replace it with a new starter motor.
Install New Starter: Position the new starter in place, secure it with bolts, and reconnect the electrical connectors. Torque the bolts to the manufacturer's specifications.
