SH-AWD Light on Acura MDX: How to Fix

Introduction

The SH-AWD (Super Handling All-Wheel Drive) system is a unique feature of Acura vehicles that provides superior handling and traction on the road. However, if the SH-AWD light on your Acura MDX comes on, it can be a cause for concern. In this article, we will discuss the possible reasons why the SH-AWD light may come on and how to fix it.

Reasons for SH-AWD Light Coming On

There are several reasons why the SH-AWD light may come on in your Acura MDX. Some of the most common reasons include:

1. Low Fluid Levels

One of the most common reasons for the SH-AWD light to come on is low fluid levels. The SH-AWD system requires a specific type of fluid to function properly. If the fluid levels are low, it can cause the system to malfunction and trigger the SH-AWD light.

2. Faulty Wheel Speed Sensor

Another reason for the SH-AWD light to come on is a faulty wheel speed sensor. The wheel speed sensors are responsible for measuring the speed of each wheel and sending that information to the SH-AWD system. If one of the sensors is faulty, it can cause the system to malfunction and trigger the SH-AWD light.

3. Malfunctioning SH-AWD Control Unit

The SH-AWD control unit is the brain of the SH-AWD system. It receives information from the wheel speed sensors and other sensors in the vehicle and uses that information to control the SH-AWD system. If the control unit malfunctions, it can cause the system to malfunction and trigger the SH-AWD light.

2. Replace Faulty Wheel Speed Sensor

If the fluid levels are fine, the next step is to check the wheel speed sensors. If one of the sensors is faulty, it will need to be replaced. This is a relatively simple process that can be done by a mechanic or a skilled DIYer.

3. Replace Malfunctioning SH-AWD Control Unit

If the wheel speed sensors are fine, the next step is to check the SH-AWD control unit. If the control unit is malfunctioning, it will need to be replaced. This is a more complex process that should be done by a professional mechanic.
