Numbering order of plugs in blocks:

• A – ignition switch;
• B – windshield wiper electric motor.

* – Installed on parts of manufactured vehicles.

We independently regulate the system

In order for the motor to operate normally, you need to set the angle. To complete this task, you will need to prepare tools, in particular, keys and screwdrivers. Before proceeding with the adjustment, you should start the internal combustion engine and let it run until it warms up. Please note that the idle speed should be at least 800 rpm.

After the internal combustion engine is warmed up, you need to open the hood and disconnect the silicone pipe, which produces vacuum from the fitting. One end of this pipe must be brought to your finger - if after this the pipe suctions, this indicates that there is a vacuum in the system. If this is the case, you will need to reduce the engine speed until the vacuum stops. Next, you will need to turn off the engine and bend the pipe until the clearance disappears. Using a wrench, you will need to loosen the fixing nuts that secure the distribution unit (the author of the video is the Engine Repair channel! And interesting!).

After the plug is removed and the inspection hatch is cleaned, you will see strips with which you can adjust the torque. The flywheel itself should be turned until it coincides with the elongated mark. These actions will allow you to optimally adjust the moment.

When everything is done, you will need a strobe or a simple light bulb with wires connected to it, the setup procedure is as follows:

1. The red cable from the light bulb should be connected to the positive terminal on the coil under the hood.
2. The black cable is the ground cable, which means it needs to be connected to the vehicle body.
3. Start the engine and then rotate the switchgear housing. The strobe should send signals in time to the flywheel. The housing itself should be rotated until the mark is aligned with the mark on the flywheel.

What's under the hood

Let's remember how the new power unit differs:

1. The distributor and ignition coil, responsible for the formation of a spark in the cylinders, have been replaced by an electronic unit - an ECU;
2. The VAZ 2109 engine compartment wiring to the injector has a number of design features. In particular: more connectors, other parameters (cross section, insulation);
3. Instead of a carburetor, a block of electronically controlled injectors is installed;
4. Automation is based on the readings of many sensors that are not on carburetor engines, which means that the wiring for the VAZ 2109 injector has more components.

There are more wires and electronics under the hood of the injection version of the VAZ 2109

For reference: In injection versions, a single ignition module is installed under the hood, in which the coil and switch are combined into a common spark-forming device.

Let’s also look at modifications to the electrical wiring on KamAZ.

Control sensors

In order for a power unit with an injection system to work, the electronic unit needs readings of the most important parameters.

And special sensors that the motor is equipped with are responsible for this:

1. DPKV (crankshaft position sensor). One of the most important parameters, without which the car will not even start. It tells the ECU when it is necessary to inject fuel and ignite it in the cylinder;
2. MAF (mass air flow sensor). Installed after the air filter and is responsible for the quantitative composition of the air-fuel mixture;
3. DD (knock sensor). Using its readings, the ECU calculates the ignition timing - the most important parameter for the beginning of the ignition phase of the air-fuel mixture in the car cylinder;
4. TPS (throttle position sensor). Unlike a carburetor circuit, where the pedal directly controls the damper, in injection engines the pedal is not connected to the actuator;
5. IAC (idle air control). Necessary for enriching the air-fuel mixture for stable engine operation when not in motion;
6. DT (temperature sensor). Available on all engines and is responsible for controlling the coolant temperature;
7. DSA (vehicle speed sensor). Based on its readings, the ECU calculates the amount of fuel and air.

The presence of sensors also modified the electrical circuit of the car - the VAZ 2109 electrical wiring to the injector has many connectors for connecting sensors to the ECU.

Tip: To install them in an old car body, you do not need to modify anything. The manufacturer has minimized preparatory work, and the instructions supplied with the power unit describe in detail the procedure for installing attachments.

ECU block

The electronic “brains” of a modern injection engine are the ECU unit.

It is he who is in charge of all the electrical processes of the power unit, and structurally consists of:

1. read-only memory (ROM);
2. random access memory (RAM);
3. a microprocessor that processes electronic signals coming from engine sensors.

The cost of an error when interfering with the operation of the ECU can be prohibitively high

Advice: it is unacceptable to interfere with its work, as well as to diagnose its operation parameters with your own hands.

All electronic components of the ECU are designed for very low voltage. Even an electrostatic discharge from touching it with your hand can damage them.

To avoid damage to the computer, technicians at service stations:

1. avoid touching the ECU plugs;
2. do not touch electronic components on its boards with their hands;
3. when flashing ROM settings, the pins of the microcircuit are isolated.

VAZ 2109 generator circuit

If you lose charge, this is most often due to a failure of the generator, and most often it is the generator brushes, but it happens that there are winding breaks and a short circuit in the circuit or an open circuit. In this case, I recommend that you familiarize yourself with this generator circuit for the VAZ 2109.

Additional tips from the professionals

By taking into account some tips and tricks provided by professionals, you can independently extend the life of your car wiring:

• car owners must periodically inspect the external condition of the insulation and all connectors by looking under the hood of their car;
• If a minor defect is discovered during inspection, the damaged wire must be replaced to prevent a short circuit. If the break is insignificant, then you can wrap it with high-quality electrical tape for a while, but it is not recommended to postpone replacement for a long time;
• A special product, WD-40, which can be purchased at an affordable price in a specialized store, will help remove the oxidizing layer from the surface of the connector;
• It is advisable to make additional protection for the engine crankcase to prevent moisture from getting on the wires.
