Acura MDX Check SH AWD System (100% Guaranteed Fix!)

Wondering what it means when your Acura MDX prompts you to “Acura MDX Check SH AWD System“?

This is an alert from your vehicle’s Super Handling All-Wheel Drive (SH-AWD) system, a sophisticated technology designed to enhance driving performance by providing optimal traction and control.

It typically indicates that the system has detected some sort of irregularity or issue which requires attention. If this warning light illuminates, don’t panic!

We’re here to guide you through understanding more about the SH-AWD system in your Acura MDX, and what steps should be taken upon seeing this alert.

How the SH AWD System Works?

Acura’s Super Handling All-Wheel Drive (SH-AWD) is a smart system that directs power to the wheels in need. It improves handling and stability, keeping you safe on any road condition.

• Intelligent Power Distribution: The system can send up to 70% of engine torque to the rear wheels.
• Torque Vectoring: Depending on driving conditions, it can direct up to 100% of those resources left or right.

Here’s how:

1. Under normal cruising, your vehicle operates mainly in front-wheel drive for fuel efficiency.
2. When acceleration happens, torque is evenly distributed between front and rear axles for balanced performance.
3. During hard cornering or slippage detection, more power shifts towards rear axle with higher distribution towards outer wheel for enhanced control.

Driving Condition	Front:Rear Torque Split	Left:Right Torque Split
Normal Cruising	90:10	Not Applicable
Acceleration	30:70	Even
Hard Cornering	30:70	More towards Outer Wheel

Remember this isn’t something you’ll have to manually control—it’s all handled automatically based on real-time analysis of your driving conditions!

Common Issues with the SH AWD System:

The SH-AWD (Super Handling All-Wheel Drive) system in an Acura MDX is a sophisticated piece of technology that provides superior handling and traction. However, like any other component, it can run into issues.

Here are some common problems:

• Malfunction Indicator: An illuminated ‘Check SH AWD System’ warning light on your dashboard may indicate potential problems.
• Reduced Traction: If the vehicle doesn’t grip as well as it used to, especially under hard acceleration or cornering, there could be a problem with the SH-AWD system.
• Unusual Noise: Any unusual noise coming from underneath the car should be inspected immediately.

Issue	Potential Cause
Check Engine Light On	Faulty Sensor
Reduced Traction	Worn Out Clutch
Unusual Noise	Damaged Differential

Here are quick steps for troubleshooting:

1. First, check if any diagnostic trouble codes (DTCs) have been stored.
2. Inspect the differential fluid level and condition.
3. Have a professional inspect all related sensors and wiring.
4. In case of worn out clutch or damaged differential, consider replacement parts.

Remember: Regular maintenance is key to avoid these issues and ensure longer life for your Acura’s SH-AWD system!

Signs of a Malfunctioning SH AWD System:

The Acura MDX’s Super Handling All-Wheel Drive (SH-AWD) system offers superior handling and stability in various driving conditions.

However, like any mechanical system, it can develop problems over time. It’s important to be aware of the signs that might indicate an issue with your vehicle’s SH-AWD system.

• Warning Light: The most obvious sign is the “Check SH-AWD” light on your dashboard. If this warning light turns on, there could be a problem with the SH-AWD system.
• Poor Traction: Difficulty maintaining grip especially during harsh weather conditions or while taking sharp turns may point towards malfunctioning in the all-wheel drive setup.
• Unusual Noises: Listen for abnormal sounds when accelerating or turning corners. Unexplained noises often signify issues related to drivetrain components.

While these indications can suggest trouble with your SH-AWD system, remember they don’t necessarily confirm it definitively. Always consult a professional mechanic if you notice any unusual behavior from your vehicle.

Steps to Diagnose Acura MDX Check SH AWD System Problems:

To diagnose SH AWD problems in your Acura MDX, follow these steps:

1. Check the error message: The first step is paying attention to any error messages on the dashboard. These can give you a clue about what’s wrong with the system.
2. Inspect the tires: Uneven wear or incorrect tire pressure affects how the All-Wheel Drive (AWD) system operates.
3. Test drive: During this, check for any unusual noises or vibrations while driving at different speeds and conditions.

If these preliminary checks do not reveal anything, consider using diagnostic tools:

• OBD-II Scanner: This device can read fault codes from your vehicle’s computer system.
• P1570: Faulty Rear Differential Clutch
• P1571: Faulty ATTS Unit
• P1572: Low Voltage Supply to ATTS Unit

You can also inspect individual components of the SH-AWD System:

Component	Inspection
Rear Differential Fluid	Check if it’s dirty or needs replacement
Magnetic Clutches	Ensure they are engaging properly
Transfer Case Fluid	Check levels and replace if necessary

Remember that diagnosing car problems should be left to professionals unless one has adequate knowledge and experience.

Checking and Replacing SH AWD Fluid:

Maintaining the SH (Super Handling) All-Wheel Drive system in your Acura MDX is essential for optimal performance. The fluid plays a crucial part, ensuring smooth vehicle operation. Follow these steps to check and replace it:

1. Park Vehicle on Level Surface – Ensuring the vehicle is level guarantees accurate fluid readings.
2. Locate Drain Plug – Located underneath your car, typically towards the rear.

To check the fluid:

• Remove drain plug using an appropriate wrench.
• Check color of fluid:
  • Healthy = Clear or Light Brown
  • Replace = Black or Metal Shavings present

Fluid Color	Action
Clear/Light Brown	Good Condition
Black/Metal Shavings Present	Mandatory Replacement

Next, replacing the fluid:

3. Drain Old Fluid – Allow all old fluid to fully drain from system.
4. Replace Drain Plug – Ensure it’s tight but do not over tighten as this can damage threads.
5. Add New Fluid – Use only recommended Acura SH-AWD fluid in correct quantity.

Remember to double-check levels after first drive! Regular maintenance ensures maximum lifespan and efficiency of your Acura MDX’s Super Handling All Wheel Drive System.
