Each of us knows that to ignitefuel-air mixture in the combustion chamber, a spark is needed. The latter is formed just by the work of the ignition system. Its design on different cars has some differences, but its main principle of operation remains unchanged. And today we will talk about how to test the ignition module VAZ-2114, as well as how to make its replacement with their own hands.
Characteristic
This element of the car is aA complex electrotechnical device whose main purpose is to generate a high-voltage current and transmit it to a candle. In total, two types of modules are used on cars: one with a single coil for each candle (separate) or one for two (block). Module ignition VAZ (2114th "Lada") - block type. Such elements include a two-screw coil. The design of this part assumes the following components:
- Low voltage terminals.
- High voltage output.
- The iron plate-shaped core.
- Primary and secondary winding.
Single-spark analogues have a slightly different design, which includes:
- Core.
- High-voltage connections through a spring contact.
- A candle.
- External terminal for low voltage.
- Secondary and primary winding.
Unlike single-spark, such coils are lighterMounted due to their special (block) design, which has a common housing. Despite the fact that there are several such elements in the unit, they all work as independent devices. This design makes it possible to apply a shortened conductor, which goes to the primary winding of the mechanism.
Ignition module VAZ-2114 - malfunctions
About the malfunctioning of this system can be judgedon the following grounds. First, the coil malfunctions can be said to fail when dialing the speed of the car. Secondly, it can manifest itself in a significant loss of power of the machine, as well as in the "floating" idle engine speed. And thirdly, non-working 1-4 or 2-3 cylinders signal irregular operation.
It should be noted that such symptoms are veryoften occur due to faulty DMRV, or the idle speed regulator. Therefore, first of all we look at their performance, and then we diagnose the ignition module.
VAZ-2114: where is this part located?
On cars of the Lada Samara-2 family this element is placed in the engine compartment.
How to diagnose the work of the module?
Checking the ignition module (VAZ-2114 "Samara-2")for operation is performed in this order. First, take out the negative battery terminal and then take out the wiring from the coil mechanism. Further we unscrew all screws and bolts that fasten the body of the element. Further all works (as before) are made with the engine switched off. We disconnect the assembly of the module, using a multimeter to measure the level of the total resistance between the terminals of the contact connector. Then we compare the results with the table norms, which are specified in the instruction manual. If the data obtained is significantly different from the table data, the circuit is short-circuited and the coil is faulty.
After installing the continuity of the wires canstart the diagnosis of the secondary circuit of the internal combustion engine - measurement of the resistance level between the ignition terminals. Based on the measurement results, we make conclusions, and if the malfunction was hidden in the coil, it means that the module must be completely replaced. There are no other solutions to this problem.
How to replace the device with your own hands? Instruments
First we need to prepare a setkeys that we use. In the course of work on the removal and installation of the ignition module, we need two end wrenches for 13 and 17 millimeters, as well as one open-end wrench for "10". The last we need in order to remove the terminal from the battery. In addition, you should prepare a hexagon on the "5". With the help of the latter, we will free the ignition module from the holder during dismantling.
Part removal process
So, how to replace the ignition moduleVAZ 2114th "Lada"? First you need to de-energize the vehicle’s onboard network. To do this, as in the previous case, remove the negative terminal from the battery (if it has not been removed before). Next you need to remove the decorative trim of the engine. You can do this by unscrewing the oil cap. It should be noted that this operation is used only by owners of VAZ with a 1.6-liter engine. One and a half liter "Samara" is not supplied with a similar engine cover.
Installation
Before you install a new item in the machine,High-voltage wires should be connected beforehand according to the module circuit. You also need to pay attention to the quality of fasteners - excess oxidation and dirt are thoroughly cleaned at the ends at the joints.
Conclusion
So, we found out what an ignition module is andhow to replace it yourself. Finally, we note that when connecting, it is important to monitor the correctness of the connection of the entire wiring circuit, since with the slightest error it will be impossible to guarantee the operability of the parts of this system.
