Japan introduced its own version of the protocol (JOBD) in 2003 for all its machines.
That is, now, generally speaking, the vast majority of even very old cars (up to 20 years old) are adapted to the computer diagnostics system. And for these historical milestones, you can assume the presence or absence of this adaptation in a particular car.
Electronic control unit
Modern vehicles are equipped with an electronic brain that integrates diagnostic sensors and control modules of all systems and subsystems of a vehicle, through which you can monitor the current state, make performance predictions, adjust various technical parameters and fix some problems.
hat he really is?
Usually it is a bunch of special controller of Best obd2 scanner, some kind of processor for data processing, special software and means of connecting all of this. Now I will explain to you in more Russian, what is the point, presenting a general concept.

Such a center is called an ECU (electronic control unit) and, for technical monitoring or making any changes and corrections to the auto system, an external diagnostic interface is connected to it.
The computer of the machine must have an external output-connector, to which a key element for such diagnostics is connected - an OBD-adapter (scanner), which converts and unifies the data flow from the computer controller so that they can be read by external plug-in devices.

Safety check for car
Internal and external security control
Before your run-up begins, perform a security check. On this page we go through how to carry out a security check in a correct and fast way.
You should perform both an external (exterior) and an internal (internal) security check. Usually, the run-up leader only asks you to perform part of the security check (eg check brakes and fluid levels), but you still have to be able and ready to perform a complete safety check from A to Z.
Remember, however, that the surveyor knows that you are nervous and you also do not need to know exactly where all the controls on all car models are - so if you are unsure of where the controls are, you can ask!
External security check
During the external safety check you should check that all lighting works properly, you should check the tires and turn signals, windscreen wipers and various liquids. Keep in mind that you do not need to pick up the dipsticks if you are asked to check the liquid levels - it is enough that you briefly describe the different containers, eg. "Here you check the oil level, if necessary fill in". What you need to check is the washer fluid, coolant, servo oil, engine oil and brake fluid.
Checklist for external security control
Turn on the parking light. Check the front lights, tail lights, reflectors and sign lights. Clean as needed!
Turn on the ignition. Turn on the dipped beam, main beam and left-hand lights. Get out of the car, check the main beam, tail light and left-hand lights both front and rear.
Check the tires on the left side (makes a quick visual check - does the pattern depth look good, the tire looks to have the right air pressure, ie is it round and not flat on the underside?)
Turn off the lights, turn on the right indicators, turn on fog lights. Step out and check the dipped beam, rear fog lights, right-hand rear lights and a quick visual inspection of the tires on the right side.
Turn off the lights, turn off all turn signal lights (reset everything to reduce the risk of driving off with the wrong lighting switched on). Ask someone else to brake while you stand behind the car and check that the brake lights work.
Finished! Note that different teachers have different ways and tricks to get one to remember exactly what to check, the above is just a recommendation - if your traffic school teacher teaches you to do the security check in a slightly different order, this is nothing unusual or if you have another system to remember everything that needs to be done.
