Checking the AWD System
Now, let’s explore the steps to effectively check the AWD system in your Toyota Highlander. It’s important to perform these checks regularly to ensure the system’s reliability.
Visual Inspection
Start by visually inspecting the AWD components, including the drivetrain, axles, and differentials. Look for any signs of leaks, damage, or excessive wear. Ensure that the components are clean and free of any debris that could affect their performance.
Road Test
Take your Highlander for a road test to evaluate the AWD system’s functionality. Find a safe and open area where you can test the vehicle on different surfaces, such as gravel, pavement, and uneven terrain. Pay attention to any unusual noises, vibrations, or handling issues that could indicate AWD system problems.

Proper tire maintenance is crucial for the AWD system. Check the tire pressure, tread depth, and overall condition of each tire. Uneven tire wear or low tire pressure can impact the AWD system’s performance, so it’s essential to keep the tires in good shape.
Diagnostic Scan
Modern vehicles, including the Toyota Highlander, are equipped with onboard diagnostic systems that can detect AWD system faults. Consider using a diagnostic scanner tool to check for any error codes or issues related to the AWD system. If you notice any codes or warnings, it’s best to consult a professional mechanic for further inspection.
Maintenance Tips
Once you’ve checked the AWD system in your Toyota Highlander, it’s important to follow regular maintenance practices to keep it in top condition. Here are some essential maintenance tips:
- Follow the manufacturer’s recommended maintenance schedule for the AWD system.
- Replace the AWD system fluid as per the specified intervals.
- Inspect the CV joints, boots, and seals for signs of wear and tear.
- Keep the wheel alignment and suspension components in check to ensure proper AWD system operation.
