Solution

1. Preparation

Tools Required:
- Wrench set
- Multimeter
- Battery terminal cleaner
- Load tester
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Maintenance

Clean the battery terminals using a battery terminal cleaner to remove corrosion.
Tighten any loose connections on the battery terminals.
If the battery is faulty, replace it with a new one of the same specifications (typically a Group 35 battery for RAV4).

3. Starter Relay and Fuse Check

Locate the fuse box and remove the cover.
Use the fuse puller tool to remove the starter relay and visually inspect it for damage.
If the relay is defective, replace it with a new one.
Check the corresponding fuse for the starting system and replace it if blown.

4. Starter Motor Inspection

If the battery and relay are functioning, locate the starter motor.
Inspect the wiring harness connected to the starter for signs of wear or damage.
Using a wrench, remove the starter motor from its mounting (usually two bolts).
Bench test the starter motor using jumper cables to see if it engages; if it does not, replace the starter motor.

5. Reassembly

Reinstall the starter motor and secure it with the proper torque specifications (usually around 15-25 ft-lbs).
Reconnect the battery terminals, ensuring they are tight and secure.
Start the vehicle to check if the issue is resolved.
