Error 0500 - "Vehicle speed sensor, no signal".
The error occurs if the controller has detected a sensor malfunction by self-diagnosis.
Reasons: ingress of moisture inside the sensor, damage to the wires.
The ignition is on, the engine is not running. Disconnect the harness block from the vehicle speed sensor. Use a multimeter to measure the voltage at contact “2” of the harness block. If the voltage is 0 V, then an open or short to ground in the sensor signal circuit or the controller is faulty. If the voltage is about 12 V, then there is a short to power source in the sensor signal circuit or the controller is faulty.
With a probe connected to the ground, several times per second touch the contact “2” of the harness block, while observing the signal of the vehicle speed on the BC. If the BC shows a speed of 0 km / h, then the controller is faulty.
Using a multimeter, measure the voltage at contact “1” of the harness block. If the voltage is 0V, then there is an open circuit in the sensor power supply circuit.
Using a multimeter, measure the voltage at contact “3” of the harness block with respect to the power supply. If the voltage is 0V, then there is an open in the sensor ground circuit. If the voltage is not 0V, then the connection is weak or the speed sensor is faulty.
Error 0501 - "Vehicle speed sensor, signal out of range."
The error occurs if within 3 seconds the vehicle speed does not match the engine speed and the engaged gear.
The procedure for finding the cause of the malfunction:
Switch off ignition. Disconnect the harness pads from the controller and DSA. Check the continuity of the electrical circuit between the contact "DSA" of the block to the controller and contact "2" of the block to the DSA, between the contact "Sensor ground" of the block to the controller and contact "3" of the block to the DSA, between the contact "1" of the block to the DSA and the main relay.
If the circuit is faulty, the wiring harness is faulty. If circuit tests normal, replace the vehicle speed sensor with a known good one. Erase the DTC and reproduce the conditions for the code. If the code is entered again, replace the controller.
Error 0503 - "Intermittent vehicle speed sensor signal".
The error occurs if the signal from the vehicle speed sensor periodically disappears.
Reasons: Unreliable contact in the harness pads connected to the speed sensor or controller. Inspect the harness pads, sensor and controller connectors for completeness and correct mating, damaged locks, the presence of damaged contacts and the quality of the connection of the contacts to the wire. Damage to the tourniquet. Check harness for damage. If the tourniquet is outwardly normal, move the appropriate block and tourniquet while observing the BC. The ingress of moisture inside the speed sensor can also lead to the appearance of code 0503, especially in spring and autumn.
Error 0504 - "A / B brake pedal switches, signal mismatch in time."
The error occurs if the signals of the limit switches "1-4 / 2-3" of the brake pedal are mismatched for more than 200 seconds with the engine running in idle mode or the number of times the brake pedal is pressed, determined by the signals of the two limit switches "1-4 / 2-3 "differs by the value of the diagnostic threshold on a moving vehicle.
The procedure for finding the cause of the malfunction:
1 If, when you press the brake pedal, stoplights do not light up periodically or continuously, check: whether the brake pedal switch rod is jammed when you press the brake pedal; check the presence of on-board voltage on contacts "1" and "4" of the brake pedal switch in a free and pressed state in accordance with the principle of operation of the switch; check the serviceability of the corresponding fuses for the brake light circuits; check the condition and reliability of the connection of the contacts in the brake pedal switch block.
2 If, when you press the brake pedal with the side lights, direction indicators, reverse, fog lights on, a weak glow of the brake lights is observed, check the reliability of the ground circuit of the rear lights.
3 Check the presence of on-board voltage on contacts "2" and "3" of the brake pedal switch in a free and pressed state in accordance with the principle of operation of the switch.
4 Check the continuity of the electrical circuit between the contact "Brake pedal switch 1" of the block to the controller and contact "3" of the block to the switch, between the contact "Brake pedal switch 2" of the block to the controller and contact "4" of the block to the switch.
If faults are found, then eliminate the found faults. Replace the brake pedal switch if necessary.
If no malfunctions are found, then check the technological gap of the brake pedal switch, if necessary adjust the gap. Erase the DTC and reproduce the conditions for the code. If the code is entered again, replace the controller.
Error 0505 - "Idle speed regulator error".
The procedure for finding the cause of the malfunction:
Start the engine and warm it up to operating temperature. With the throttle valve closed, using the BC (some models support this function), change the idle speed in the range from 800 to 1000 rpm. If the revolutions change in accordance with the specified ones, then turn off the ignition. Disconnect the connector from the IAC. Using a multimeter, measure the resistance of the IAC windings. If the resistance between contacts "A" and "B", "C" and "D" PXX is within 40 ... 80 Ohm, and the resistance between contacts "A" and "D", "C" and "B" PXX is more than 1 megohm, then check the reliability of the connections in the block. Check the pressure in the fuel supply system, check the injectors for leaks. Otherwise, replace the IAC.
Switch off ignition. Disconnect the connector from the IAC. Connect the idle speed control tester to the IAC. Start the engine. Using the tester, control the IAC by setting an increase or decrease in idle speed. If the revolutions do not change in accordance with the specified ones, then check the air passages of the idle system, if they are normal, replace the IAC.
Switch off ignition. Disconnect the ignition harness connector from the controller. Using a multimeter, measure the resistance in the circuits between the contacts of the PXX pads and the pads to the controller: "A" and "PXXA", "B" and "PXXB", "C" and "PXXC", "D" and "PXXD". If the resistance is less than 1 ohm, then the controller is faulty. If the resistance is more than 1 Ohm, then eliminate open circuits.
Error 0506 - "The idle speed regulator is blocked, low speed".
The error occurs if the current idle correction exceeds the threshold values.
Reasons: over-lean or over-rich mixture, air filter clogging, IAC or wiring harness malfunction.
Check air filter for contamination. Check the correct connection of the crankcase ventilation hoses. If faults are found, then they must be eliminated.

Disconnect the harness block from the controller. With a probe connected to the power source, check the pin of the harness block, during the previous check of which the light came on. If the probe light comes on, then the control circuit under test is shorted to ground. If the probe light does not light up, then the controller is faulty.
Error 0509 - "Idling regulator, short circuit of the control circuit to the power source or open."
The error occurs if the self-diagnosis of the idle speed regulator control driver has detected a short circuit to the power supply or no load at the output.
The procedure for finding the cause of the malfunction:
Connect the harness block to the controller. Using a multimeter, measure the resistance between the IAC contacts and ground. If, for all checks, the resistance is 19 ... 21 kΩ, then there is a weak connection in the IAC harness block.
Disconnect the harness block from the controller. Using a multimeter, check the resistance of the wire between that contact of the harness block, where the resistance is not 19 ... 21 kOhm, and the corresponding contact of the controller block. If the resistance is less than 1 Ohm, then the controller is faulty. If the resistance is more than 1 Ohm, then repair the open circuit.

The error codes of the VAZ 2110 are presented in numerical designation on the display, and they are transmitted from the phase sensors to the on-board computer. This is convenient, but a novice driver will not be able to understand much and will not be able to figure out how to use this equipment. But you need to know and be able to, since the system, thanks to the built-in self-diagnosis function, will help to identify a malfunction in the early stages, which means that it is possible to eliminate it in a timely manner.

Diagnostics
There are two ways to diagnose the state of vehicle systems. Let's start with the first one, which does not involve the use of additional equipment.
To start the self-diagnostic function, you need to press the button that resets the mileage for the day. We turn on the ignition. You will see how the arrows on the devices begin to move from one position to another. It means that the diagnostics of the VAZ 2110 has been launched and information has begun to flow from the phase sensors to the ECU. After the completion of the process, the RAM will transfer numbers to the display that will show the state of the car systems.
VAZ 2110 car
Decoding combinations
When the self-test is completed and the number 0 is displayed, this means that everything is in order with the vehicle and all systems are working as expected:
- if 1 is highlighted, this indicates that there is a problem with the microprocessor or the RAM is malfunctioning;
- 4 - high voltage in the network, more than 16 V;
- if 8, then low.
If the malfunction is not one, but several, then a figure equal to the sum of the malfunctions will be displayed. If 6 lights up, then this will mean the sum of the numbers 2 and 4. If 14, then most likely there are three malfunctions at once, namely 2, 4 and 8.
The simplest diagnostics available to the driver without the use of additional equipment. Of course, it will help to identify some malfunctions, as well as to show the state of the nodes and the VAZ 2110 system as a whole. But for the specific determination of all faults and the decoding of the information coming from the phase sensors, additional means are needed. For example, one that provides more data.
Daily mileage reset button Diagnostics using additional tools
To diagnose a car, including a VAZ 2110, various equipment is used, which is connected to a special connector. Thanks to this equipment, which is not particularly complex and expensive, you can get a complete picture of the state of the car.
At the service station, a personal computer is used, to which data from the phase sensors are transmitted through a special cable.
Auto diagnostic adapter Bluetooth devices have appeared on the market, allowing diagnostics using a smartphone, tablet or laptop.
They work according to the scheme. The device is connected to the connector, the ignition is turned on and the diagnostic process begins. The data comes from phase sensors to the ECU. From it to a mobile device, on which specialized software must first be installed.
This makes it possible not only to obtain more data, but also to present them in a more visual form. This method allows the driver, even with little experience in operating a car (in our case, the VAZ 2110), to get all the data about his car.
But most of the drivers prefer to carry out diagnostics at the service station. So that you are aware of the data that the on-board computer gives out through the RAM from the phase sensors, we will present the decoding of common errors.
Decoding combinations
If problems arise with the electrical equipment, they must be corrected immediately. The error code 1602 will show that not everything is in order in this issue.
Sometimes error 1602 can be simply dropped and does not appear later. Socialists call such data "good."
Error 1602 sometimes appears if:
- the battery was disconnected for a while;
- there was a power surge when starting the motor, for example, in cold weather.
But if error code 1602 appears all the time, you need to check the entire network. There may be a cliff. If the 1602 error code is constantly appearing, you can try to strip the battery terminals. Check if they are well secured. Didn't help, is error 1602 still appearing? Check the circuit. You need to start from the positive terminal of the battery. Start with an electrical fuse and a fuse link.
DPDZ. Sometimes it happens that the cause of error code 1602 is an alarm that can block the controller circuit and affect the readings of the phase sensors. In such a situation, you need to file a claim with the company that dealt with
- low air consumption, which depends on the speed of rotation of the crankshaft;
- how much the throttle valve is open;
- several cycles have passed since the problem occurred.
If the error appears periodically, then you need to:
- check the condition of the air barrier;
- fastening the wiring block with the ECU;
- check IAC;
- clean the throttle pipe.
Another error that can occur is 0300. 0300 appears in cases when the RAM detects frequent misfires.
If the error code 0300 is displayed constantly, then you need to check the following components:
- spark plug;
- nozzles;
- ignition system;
- increased or decreased compression level may cause the appearance of code 0300;
- also code 0300 can appear in case of a wiring violation.
You cannot ignore the appearance of error 0300. In the future, this may lead to deterioration in the operation of other nodes.
It is not difficult to master the diagnosis of a car, in particular a VAZ 2110. It will extend the service life due to the timely detection of faults that are recorded by the phase sensors.

1 What State X1 Can Do - Information About Computer Features
- Diagnostic tester. It performs the function of a digital speedometer, tachometer, controls the operation of the power unit and the throttle valve (tuned or standard), reads system diagnostic codes, notifies about the voltage of the mains in the car and the temperature of the engine.
- Trip computer. A useful and convenient mode. In it, the on-board computer at the VAZ State shows the speed (average value) of driving for one trip, the distance traveled by the car, the remaining fuel in the tank and its consumption per trip, travel time. The BC also predicts the mileage on the remaining fuel and has a counter of the latter.
- Supervisor. The device is equipped with an idle time counter and non-volatile memory, it notifies the driver about non-switched off direction indicators and dimensions, as well as about rollback (spontaneous) of the vehicle.
- Signaling device. The state reports that the speed threshold has been exceeded, that there is a problem with the on-board network, and that the power unit overheats potentially unsafe for a car.
- On-board computer VAZ 21099
- Checking the throttle position sensor
- Dingo on-board computer - practicality with a minimum budget
- Autoscanner for self-diagnosis of any car
In addition, State X1 has three additional functions that have pleased domestic motorists. The Tropic mode implies automatic control of the cooling system of the car, Plasmer is responsible for drying the candles and their subsequent warming up to a temperature that makes it possible to cold start the engine without problems, Afterburner resets when switching the fuel from gas to gasoline and vice versa.
A small nuance. The Afterburner function works exclusively with high-quality brands of gasoline (95 and higher). Installation of State X1 is carried out without the slightest difficulty in the plug on the dashboard.
You will need instructions for installing the BC in a specific VAZ car model. The installation principle is the same. It is necessary to remove the trim from the dashboard, and then alternately connect the one-color factory wiring with the wires of the on-board computer. State X1 does not need special tuning. Install the BC, turn on the ignition, start the device, and it immediately goes into trip computer mode. If you need to switch to the diagnostic mode, press the CORR button. The BC goes into the alarm (emergency) mode on its own.

1 Standard options on-board computer State X5 M
The next useful option is Plasmer. By enabling this function, the owner of Lada Kalina triggers an inflow of additional impulses to the electrodes of the candles. So on frosty days, the Lada starts up much faster, and the computer gives out fewer error codes. The "View ECM Errors" function is designed to visually view the codes.
Another very useful option for Russian drivers is Fuel Quality Control. Using the “-” or “+” icons, the on-board computer shows the percentage of the quality of the refueled petrol. Thanks to the "Powertrain parameters" option, the Lada driver has the opportunity to see a clear picture of the engine condition; the time spent heating it; as well as the battery charge level and voltage indicator in the gauges in the instrument panel. In the event of a malfunction of the motor elements, the device generates error codes with the name "Engine ...".
The State X5 M on-board computer on Kalina also has a built-in display settings function. Using it, the driver can display those indicators that are of the greatest importance to him on the screen of the device. With the same option, you can adjust the color, contrast and brightness of the display.
Another useful feature is the Petrol Pump Diagnostics. It controls the pressure and power of the system. This option also makes it possible to determine the state of each injector of the Lada injector.

3 DIY installation of the device - how to avoid mistakes
Every motorist should have a universal device to diagnose his car.
You can read, reset, analyze all sensors and configure the on-board computer of the car yourself using a special scanner ...
- instructions for connecting a computer;
- a set of new electrical wiring;
- screwdriver;
- double sided tape;
- soldering iron.
First, disconnect the negative terminal from the Lada battery, and then unscrew the 4 screws that secure the standard ashtray. We take it out and find a block with contacts for turning on the alarm. We take out the block - we will connect the on-board computer to it.
Next, we take out the orange wire, which is connected to the seventh pin, and instead we connect the red and white wire from the computer. After that, insert the orange wire into the single connector of the red and white cord. Disconnect the red-black cord from the tenth contact and install the red wire from the computer instead. Insert the previously disconnected black wire into the single connector of the red wire.
If the computer is not working, you need to pull it out and use pliers to strip the ends of the electrical cords. If grooves have formed during the installation process, they can be soldered using plastic or metal strips.
Do you still think that car diagnostics is difficult?
If you are reading these lines, then you have an interest in doing something in the car yourself and really save money, because you already know that:
- STO lomat big money for simple computer diagnostics
- To find out the error, you need to go to the specialists
- Simple wrenches work in the services, but you can't find a good specialist
And of course you are tired of throwing money away, and there is no question of driving around the service station all the time, then you need a simple ELM327 AUTOSCANNER that connects to any car and through a regular smartphone you will always find a problem, redeem CHECK and save a lot! !!
We have tested this scanner ourselves on different machines and it showed excellent results, now we recommend it to EVERYONE! So that you do not fall for the Chinese counterfeit, we publish here a link to the official website of the AutoScanner.

Owners of Russian cars know firsthand what meager capabilities a regular BC has.
For example, my car does not even have an engine temperature indicator ((
In addition, I would like to have a device for diagnosing errors and, if necessary, be able to reset them.
At first I wanted to buy a Bluetooth scanner, but for work I need to connect a device with Android OS, which is not very convenient. Therefore, it was decided to purchase an additional on-board computer.
