The ZMZ engine on the UAZ Patriot is simple in its design. This ensures its reliability and wear resistance. However, from time to time malfunctions occur in it, the calculation of which is carried out by the UAZ Patriot ECU. It displays error codes for UAZ “Patriot” with engine 409 on the car’s on-board computer.
Purpose of the on-board computer
New cars from the Ulyanovsk Automobile Plant are equipped with an electronic control unit. This allows the system to quickly diagnose units to identify and specify problems. To visualize them, you need an on-board computer on the UAZ Patriot. It is a device on the screen of which information received from the ECU and other vehicle systems is displayed.
If there is no computer, the codes will be displayed on the instrument panel and indicated on the Check Engine indicator without specification. In this case, the owner will have to undergo computer diagnostics to clarify the type of malfunction and eliminate it.
Period from 1965 to 1984
During this period, the automaker equipped its products with electrical components available to the domestic industry. Some of them were known for a long time, others were experimental, as evidenced by videos from previous years, and which had to prove their suitability.

Lighting control
In particular, the controls and a number of main units migrated from its predecessor, the GAZ-69. Thanks to this, the price of the car remained the same.
On models of the first years of production, a foot light switch was installed, which had several operating modes:
- The first position activated the circuit for switching the low beam headlights and side lights;
- In the second position, the low and high beam headlight circuit was activated.
For reference: Turning on the headlights (low or high beam) led to the turning off of the front side lights.
Foot switch for headlights and parking lights
The modernized light switch has a different operating algorithm:
- The first position supplies power to the side lights only;
- The second position is side lights and low (high) beam headlights.
Caution: This algorithm with non-switchable dimensions is a mandatory requirement for passing MOT. The factory instructions give recommendations for reworking the old circuit, in which it is important not to mix up the contacts of the foot switch.
The most correct option is to replace the old switch with a modern one, which uses only 3 contact groups.
Also, on older versions of the “452” there was no alarm, so in the electrical diagram:
- An RS-57 breaker relay was installed (mounted in the wiring gap from the “+” terminal of the battery to the direction indicator switch);
- The middle contact of the relay closed the indicator light on the instrument panel.
See also the Ural motorcycle wiring diagram.
Ignition system
Ignition of UAZ 452 model 1968
Also on the “452” contact ignition was installed:
- The “+” wire from the battery supplied power to the ignition coil;
- From the coil, the high-voltage wire transmitted the impulse to the breaker (distributor) and further to the spark plugs.
Period from 1985 to 2013
In later modifications, with the advent of injection, some changes were made to the ignition:
- An additional resistance was installed in the “battery-ignition coil” circuit;
- A separate wire from the starter was laid to the coil wire connection terminal (past the additional resistance)
- On later models, an additional starter relay was installed in the circuit.
Control devices UAZ 452
For reference: UAZ vehicles also have different control devices. Some machines had an ammeter installed instead of a voltmeter. The UAZ 452 wiring made it possible to connect a voltmeter into the wire gap between the battery and the ignition system.
Conclusions: along with the car, the electrical circuit also changed. This factor should be taken into account when carrying out scheduled repair work in order to eliminate emergency situations.

Error codes
Each error has its own identification number. For the convenience of users, errors are sorted into the following groups:
Group 01
01 series codes occur due to problems with the main sensors. For example:
- coolant temperature indicator;
- air temperature;
- mass air flow;
- throttle position.
The most common error in this group is p0106. It indicates problems with the pressure sensor inside the intake manifold. Its main reasons are:
- Sensor oxidation. To solve it, you need to clean the contacts of the device and treat the surface with a special solvent.
- Air supply tube clogged. In this case, you need to use cleaning agents and carry out mechanical cleaning. To do this, you can use a steel cable whose width does not exceed the diameter of the tube.
- Incorrect operation of the sensor. The solution is to replace the component.
After eliminating the code, you must reset and restart the engine with diagnostics. If necessary, carry out thorough cleaning.
Group 03
Errors occur when there is a problem in the ignition system. Common ones are:
- 0300 – misfire;
- 0301-0304 – the cylinder in which misfires occur. The error occurs due to clogged or incorrectly installed spark plugs;
- 0327 – detonation error in cylinders;
- 0335 – incorrect operation of the crankshaft sensor;
- 0340 – problems with the functioning of the phase sensor. To solve it, just clean the device using special liquids.
Group 04
Major deficiencies in category 04 require third-party intervention. These include:
- 0420 – catalyst malfunction due to blockage or device failure. This prevents the exhaust gases from escaping correctly;
- 0443 – errors in the functioning of the adsorber valve, which prevents harmful fuel vapors from entering the atmosphere;
- 0444, 0445 – short circuit in the adsorber valve;
- 0480, 0481 – problems with fan operation.

Code 0704
The appearance of the code indicates a problem with the clutch switch (limit switch), which is a weakened tension spring. To solve it, you need to get the part and identify the exact reason for the lack of signal. If necessary, contact service.
Code c3472
The error occurs when the camshaft position sensor is faulty. To eliminate it, it is necessary to check the timing of the gas distribution mechanism and the integrity of the wiring. If necessary, replace the camshaft and crankshaft sensors with new ones.
Error codes can indicate more than just mechanical problems. So, the number 2187 indicates an incorrect composition of the air-fuel mixture. External signs of a problem are loss of power at idle and when starting off. The main cause of the malfunction is low-quality fuel. In this case it is necessary:
- drain the fuel from the tank;
- if possible, flush the fuel system and tank;
- Fill with new fuel of better quality.
The full list of codes can be found in the car's user manual. In most cases, problems are not signs of significant problems. But if repaired poorly, they can lead to vehicle failure. If you are not sure that you can deal with the problem yourself, contact a professional service.

Automatic transmission error codes (Opel Omega B)
All automatic transmissions for Opel Omega B (Opel Omega B) are produced in the automatic transmission department
GM transmissions in Strasbourg (France). You can clear automatic transmission error codes by using a diagnostic tool called TEK . Information from the electronic parts of the automatic transmission and its controller is transmitted to pin 3 of the standard connector (XD). You can also clear the automatic transmission error codes of an Opel Omega car yourself if you have a K-line adapter and software.
UAZ error codes
On UAZ Hunter cars with Euro-2 injection engines, an engine management system with an electronic control unit (controller) of the Mikas 7.2 or M1.5.4.U AUTRON type is installed, which includes a diagnostic function for sensors and actuators, which determines the most likely malfunctions of the fuel injection system and detecting a malfunction of the controller itself.
If a malfunction is detected during engine operation, the controller stores the corresponding fault codes in its RAM and at the same time turns on the orange engine malfunction warning lamp.
You can read fault codes in the field by switching the electronic control unit (controller) to self-diagnosis mode.
After the computer is switched to self-diagnosis mode, the engine malfunction warning lamp should display code 012 , this means the on-board self-diagnosis system has started operating. The following codes will indicate the fault or faults that have occurred. Each code is repeated three times.
After all existing fault codes have been displayed, the control lamp again displays code 012 and repeats the fault codes again.
