Review of the first generation Toyota Electro Multivision (EMV) system

Good day!

Today you will not surprise anyone with a monitor in the car. They are put regularly even in frets. We are all accustomed to controlling the functions of the car by touching the screen or watching TV while standing in traffic. Of course, this was not always the case. Such devices have their own history of development, which is no less interesting than the history of, for example, personal computers.

So, today we consider the firstborn of such systems from the company Toyota. For the first time, EMV was introduced 30 years ago, back in 1985, as an option for the Toyota Soarer in the back of the MZ12.

This is what the “saury” looked like:



By the way, next year the next generation Soarer was introduced, in which the system was significantly upgraded.

In 1985, the system could do the following:

• Show electronic tachometer, speed, transmission and other useful information;
• Show a graph of fuel consumption;
• To remind of the approaching car maintenance;
• Show tv.

System composition

All EMV units of the first generation are shown in the figure:



In addition to the frames and wires can be noted the following blocks:

• 86111-24010 MultiDisplay (CRT TV) - The real color CRT monitor with a diagonal of about 6 ';
• 86116-24010 Controller, Video - the top element in a stack of three blocks. Responsible for displaying pictures on a monitor and contains, among other things, monitor BP;
• 86010-24010 Tuner Assembly, Television - TV tuner (middle block). Two antennas at the rear of the body were used to receive the television signal;
• 86112-24010 Computer, Multi-Display (Computer CRT Display) - Computer (lower block). Responsible for the formation of graphics, polls various blocks of the car for their status. For example, it reads the automatic transmission mode (PRND-2-L) and displays the corresponding icon on the screen. He also diagnoses the car;
• Display Screen Selection Switch - switch information display modes. Located to the left of the steering wheel. The top three buttons: Information display / fuel consumption / maintenance. The bottom button is a TV.
  
  
  
  
• 86170-24010 Remote Control - wired remote control. Used in TV mode to switch channels and settings. On the front side is a block of buttons. Left, under the lid, additional buttons for setting. On the reverse side printed instructions for setting up channels.
  
  
  
  

Information display modes

Let us consider in more detail what the system is capable of.

So, turn on the car:



For 2-3 seconds, System Check is displayed on the screen. At this point, the systems listed on the screen should be checked, although some sources state that this is nothing more than the start screen.

After loading the system, the Drive Screen is turned on



In this mode, the following information is displayed:

• Engine speed. In the form of figures and in the form of a graph
• The position of the lever automatic transmission;
• TEMS suspension mode (SPORT, NORM, AUTO);
• The mode of the electronic control system automatic transmission (PWR, NORM, ECON);
• In case of overdrive shutdown (overdrive), the OD OFF icon is displayed;
• When the cruise control is on, the set speed is displayed;
• Shows reminders of the impending service;
• In the event of a fault, the Check Engine icon lights up.

Press the middle button on the mode switch and drop out on the screen of information about fuel consumption.



Here, in the form of graphs, the fuel consumption is displayed (in km / l), instantaneous - on the right, history in a few minutes - on the left.
The right button will show us the service screen.



The system allows you to select the maintenance procedure (for example, change the brake pads) from the preset list and specify the mileage in kilometers through which the procedure must be repeated. As soon as this mileage is approaching, a reminder will be displayed on the screen.

And finally, the TV. Works like a normal TV, is controlled from the remote. Shows only if the car is standing still.



I recommend to watch a video about how it all works live.
