The ignition module VAZ-2114: features and characteristics

Each of us knows that to ignite the fuel-air mixture in the combustion chamber needed a spark. The latter is formed because of the operation of the ignition system. The design on the different cars has some differences, but the main its principle of operation remains unchanged. And today we'll talk about how to check ignition module VAZ-2114, and how to replace his hands.

Characteristics

This element of the vehicle is a complex electrical device, the main purpose of which is to generate the high voltage and transfer it to the candle. There are two types of modules – with one coil for each spark plug (single) or for two (block). The ignition module VAZ (2114-y «Lada») - block type. Such elements include dohistory coil. The design of this part requires the following components:

• Terminals low voltage.
• The output of high voltage.
• Iron plate of the core.
• Primary and secondary windings.

Odnoskatnye same analogues have a slightly different design, which includes:

• The Core.
• High-voltage connection via a spring contact.
• Candle.
• External terminal for low voltage.
• Secondary and primary winding.

Unlike odnodiskovyh such coil is easier to mount due to their special (block) structure, which is the General case. Despite the fact that the block has several of these elements, they all work as independent devices. This design enables the use of a shortened guide that goes to the primary winding mechanism.

The ignition Module VAZ-2114 - fault

About the improper operation of the system can be judged by the following criteria. First, about the defects of the coil can speak failures when the set vehicle speed. Secondly, it may occur in a considerable loss of power, as well as in “floating” engine idle speed. And third, about the signal outside of 1-4 or 2-3 cylinders.

It Should be noted that these symptoms often occur due to faulty MAF, or IAC. So first of all look at their performance and then diagnose the ignition module.

The VAZ-2114: where is this item?

Cars «Lada Samara-2” this element is placed in the engine compartment.
The easiest way to discover it – to find the high voltage wire. One end is drawn to the candles, and the second goes to the ignition module.

How to diagnose the module?

Check the ignition module (VAZ-2114 "Samara-2") on the performance is executed in such sequence. For a start remove the negative terminal of the battery, then took out from the reel mechanism wiring. Next, Unscrew all the screws and bolts that fasten the housing element. Then everything works (as before) are made with the engine off. Detachable Assembly of the module, with a multimeter measuring between terminals of the connector level is the total resistance. Then compare the results with the table of standards specified in the manual. If the received data are significantly different from the table in the smaller side, so in the car there is a short circuit, and the coil came into the fault.

After installation, the continuity of the wires you can start the diagnosis of the secondary circuit of the engine – the measurement of resistance between terminals of ignition. The results of measurements draw conclusions, and if the fault was hiding in the coil, then the plug should be fully replaced. Other solutions to this problem.

How to replace the device with your hands? Tools

First we need to prepare a set of keys which we will use. In the course of execution of work for removing and installing the ignition module, we need two Allen key 13 and 17 millimetres, and one Rozhkova key on “10”. Last, we need to remove the terminal from the battery. Moreover, it is necessary to prepare the hex on “5”. With the last we are going to release the ignition module from the holder when removing.

The Process of removing details

So, how do you replace the ignition module VAZ 2114-y «Lada»? First you need to disconnect the onboard network of the car. For this purpose, as in the previouscase, remove the negative terminal from the battery (if it is not removed before). Next you need to remove the trim motor. This can be done by loosening the cap Gulf oil. It should be noted that this operation is used only with a VAZ 1.6-liter engine. A-liter "Samara" not provided with a similar plate of the engine.

In the next step we take out of the module connector with wires and high voltage wires. With key 13 Unscrew the two fixing bolt of the crankcase, horn 17 unscrews the last bracket. Then this part is extracted safely from the engine compartment outward. The module itself is released from the holder by using hexagon 5 mm.

Installation

Before you install a new item into the machine, please connect the wires according to the diagram of the module. You also need to pay attention to the quality of the fixtures – excess oxidation and dirt are thoroughly cleaned at the ends in the joints. Then the ignition module VAZ 2114-y «Lada» can be safely installed on a regular place. The Assembly element in the reverse sequence. After you have connected the ignition module VAZ-2114 have to have and check out the details. If all of the above symptoms of trouble are gone, then you did everything correctly.

Conclusion

So, we found that such a ignition module and how to replace it myself. Finally, we note that when connecting, it is important to follow the correct connection of all circuit wiring, because at the slightest mistake, it will be impossible to guarantee the function of the components of this system.
