Makita AWS Auto-Start Wireless System – UPDATED:
The Makita Automotive Wireless System (AWS) was first introduced in 1997 and it is still one of the most popular automotive wireless systems today. It has been used in over 40 million vehicles worldwide since its introduction.
The system consists of two main components; a transmitter and receiver unit called the “Auxiliary Units” or AU’s. Both units are connected via a radio frequency link between them.
In order to operate the AU’s properly, they must have a power source such as batteries or an AC outlet. For safety reasons, the AU’s are not allowed to be plugged into any type of electrical outlets.
They must always remain plugged into their respective AU charger when not in use and disconnected from each other when charging or discharging.
There are three types of AU’s available; Remote, Mobile and Base Station. Each type is designed to work with specific vehicle models.
There are also different versions of each AU; some have additional features while others do not. All versions share many common characteristics including their ability to communicate wirelessly using a standard 2.4 GHz band. However, there are differences in the way these units connect to your car’s computer system and how they function under various operating conditions.
Makita Auto-Start Wireless System uses a standard protocol called SAE J1850, which is an acronym for the Society of Automotive Engineers (SAE). The letter “J” refers to an industry task force made up of engineers and technical staff from various companies, while the number “1850” usually represents the year this standard was accepted by SAE members.
There are many advantages to a J1850 standard, in that allows the AU’s to transmit information both ways. For instance, the Auxiliary Units can communicate with each other, alerting the driver if they have been connected improperly or if there is some sort of problem with the electrical system or wiring of your vehicle.
This can be helpful in preventing potential damage to your vehicle or injury to you or your passengers.
Makita AWS and other similar systems allow the AU’s to display messages on a small screen in the upper right corner of the dashboard. This display is very useful when attempting to program or operate the devices.
Unfortunately, early versions of these display screens were not very easy to see under certain lighting conditions or from certain angles. If you were not sitting in the driver’s seat and facing it directly head on, the messages would be very difficult to read. Unfortunately this also meant that some messages might go unnoticed until the next time the driver got into the vehicle or even worse; while driving!
Fortunately, with later models that problem was solved by making the display more visible from a wider range of angles and lighting conditions. To further enhance your safety, messages are now displayed in red text to draw your attention to them.
With all the choices of Auxiliary Units available, it can be a bit confusing selecting the right ones for your particular vehicle. If you would like assistance in selecting which units are best suited for you needs, please ask one of the sales staff to help you at the time of purchase.
They will be happy to assist in making sure you get exactly the ones you need.
Another thing to keep in mind, while the manual does a good job of explaining the basics, it does not cover every possible scenario and situation you may encounter. If you have questions that are not answered in this manual or on the labels located on the AU’s themselves, please contact us immediately.
So without further ado, I present to you the most up-to-date version of the Makita Auto-Start Wireless Auxiliary Units Owner’s Manual.
