This system transfers torque from the front to rear wheels as needed in the MDX in conjunction with your transmission.

Why Does My Acura MDX Say Check SH AWD?

Check SH-AWD is a warning that indicates that your Acura MDX’s Electronic Control Unit (ECU) has detected a problem, preventing you from using all four wheels. 

You may not be able to start or shift your vehicle correctly if you have this malfunction. Your Acura MDX may display a warning light for a variety of reasons.

Common Causes of SH-AWD Problems

  • Front differential fluid level is low.
  • In the AWD system, the wrong type of fluid was used.
  • Front differential fluid level is incorrect.
  • The transmission control module (TCM) and front and rear axle sensors are damaged or faulty.
  • An automatic gearbox pump or torque converter clutch solenoid valve that is damaged or faulty.

Is it safe to drive with the SH-AWD light on?

When you experience abnormal vibrations coming from the drive wheels or you are driving in bad weather, I recommend you have the system checked by an Acura Dealer.

In good weather, you might be tempted to take the risk, but if the first problem is not addressed, you may have to pay more for subsequent damage.

Your car should be inspected as soon as possible, even if you are able to drive it, to avoid any additional damage.

It is best to have a professional test the parts if you are unable to do it yourself.

It is then possible to replace those that are faulty once you have identified them. A bad wiring inside one of these sensors is another common cause of this problem;

My recommendation is to replace only that part if yours is experiencing problems (and they’re not permanently damaged) so that you can eliminate any additional problems without spending unnecessary time or money on repairs.
