Computer diagnostics of errors in Chevrolet Cruze, codes and decoding

When strange numbers or symbols appear on the Chevrolet Cruze instrument panel, this means an error due to a car malfunction, which is important to be able to decipher, reset and correct the condition of your vehicle. With each new version of the Chevrolet Cruze it becomes more and more difficult to read the codes, because... their number increases significantly. But let's look at how to behave in a situation where an error appears on the panel, how to clear the code yourself, when computer diagnostics of a car at a service station cannot be avoided, what PC programs will help you with self-diagnosis and a complete list of codes for the 2014 Chevrolet Cruze.

What to do when the main error messages come on

Error codes 84 and 89 on Chevrolet Cruze: causes, diagnosis and troubleshooting

Electronic control units of modern cars have diagnostic functions, which greatly simplifies life for drivers. If the ECU sees an error in the operation of the engine and other units, the driver is notified about this by the corresponding information on the multimedia system display.

The Chevrolet Cruze also performs automatic diagnostics, capable of notifying the driver of various problems. Most often, owners of this car model have to deal with errors 84 and 89.

They signal relevant problems that must be corrected in order for the engine to operate normally again.

Chevrolet Cruze: error code 89

All Chevrolet Cruze owners have to deal with error code 89.

This error does not indicate a failure in the system, but warns the driver that it is time to undergo scheduled maintenance.

The electronic control unit informs the driver about error 89, based on the speedometer readings. The following course of action is suggested when error 89 lights up on the display:

1. The driver must check the official Chevrolet regulations, from which it will become clear what specific work needs to be done for the achieved mileage;
2. Next, you need to go purchase consumables: oil, filters, and so on;
3. The final step is to perform all Chevrolet recommended work on the Cruze at your current mileage. Depending on the complexity of the scheduled maintenance, the driver can perform it independently or at a service center.

It is worth noting that in rare cases, the cause of the Chevrolet Cruze error is the incorrect operation of the speedometer, which transmits incorrect information about the mileage to the electronic control unit.

Chevrolet Cruze: error code 84

Another common error that Chevrolet Cruze owners often encounter is 84. It less accurately tells the driver what work needs to be done to fix the problem.

This error signals that the electronic control unit has reduced power in order to preserve engine elements.

In other words, the car will begin to accelerate “stupidly” and spend more fuel if you ignore error 84 in the Chevrolet Cruze and continue to drive with it.

At the same time, there may be a lot of reasons why error code 84 appears on the Chevrolet Cruze. The following are the most common:

1. Problems with the throttle valve. Chevrolet Cruze vehicles are equipped with electronic throttle. The following problems most often arise with it:
   Blockage. The standard “disease” of all chokes is a blockage that prevents the damper from completely closing. Since the ECU controls the position of the throttle valve, it indicates to the driver with error 84 that it is not closing completely. In such a situation, you will need to clean the throttle valve;
2. Erase a contact. Under the throttle cover there are contacts and tracks - 4 pieces each. A common problem is the center contact rubbing off. Due to the fact that the contact does not reach the track, malfunctions occur in the throttle, which are detected by the ECU. To correct the situation, you need to press the contact in the track using tweezers. But this solution can be called rather temporary, and if such a situation arises, a complete replacement of the throttle will be required. Please note: In rare cases, error 84 occurs due to the accelerator pedal, which has the same electronic unit as the throttle, and a similar “disease” of erasing the central contact.
3. Low coolant. Perhaps the simplest reason for error 84 in the Chevrolet Cruze. If the pipes through which the coolant passes overheat, the ECU will know about this and notify the driver with code 84. In such a situation, it is enough to add coolant to the tank;
4. Problems with the electronic control unit. It is possible that error 84 in the Chevrolet Cruze arose due to problems with the unit itself, or rather with its contacts. It is recommended to clean oxidized contacts, especially 42, 43, 44, 45 and 46; most often, oxides on these five contacts can lead to error 84.

Types of electronic control units and their purpose

An electronic control unit (controller unit) is a microprocessor with software capable of analyzing data on the operation of subsystems, displaying error codes on the dashboard, on-board computer and transmitting control commands to the electronic-mechanical actuator where the failure occurred.

The ECU receives information about the quality of the fuel mixture (oxygen sensor), the position of the throttle valve and gas pedal, various temperature and level indicators (oil, coolant, engine temperature), the operation of the crankshaft and timing belt, pressure in hydraulic units and tires, and much more. to control all systems.

In total, a basic car can be equipped with 10 or more sensors and several controller units, which are divided into types:

The blocks are integrated into a common control system and operate in constantly changing modes, ensuring the joint correct operation of all mechanisms.

Each malfunction is systematized and defined by its own code, which is displayed on the on-board computer in the form of a “check” of a general indicator or a specific error code during computer diagnostics.

Diagnostics involves connecting the ECU via an OBD 2 scanner adapter to a laptop (computer or smartphone) with the necessary software installed.

Cruz Chevrolet code 95 how to remove

Good afternoon, I can’t clear the error - code 95, it says that there is a mechanical error - open circuit - short circuit - no grounding.

As I understand it, the whole problem is in these yellow clips in the photo and the contact has come off due to the fact that its passengers constantly touch their feet under the seat?

Well, remove the terminal and check the contact under your seat.

If everything is ok there, then it means that the snail on the steering wheel may have broken and the SRS unit does not see the airbag

norfolk197609, I looked in, there’s some kind of homemade thing there, there’s a resistor screwed in manually, on the passenger side it’s not there at all and the wire is stupidly hanging out - tomorrow I’ll go to the electricians, let them look at what kind of heresy there is.

norfolk197609, the car is used - but according to the scanner the airbags are all active and in working position and there are no traces of their activation and the car was completely checked for painting, etc. - probably the craftsmen themselves tried to remove the error

sell199505, after the airbags fire, the craftsmen solder a transistor with a resistance into the circuit so that the system thinks that all the airbags are active. So when you scan you see that they are there. Remove the steering wheel cushion and see if there is a plug there

norfolk197609, I looked at the steering wheel recently, they took everything apart - everything is in place, it’s just a mess with wires under the seat, either the passengers mutilated them with socks or whatever - the car is not broken at all. Yes, I looked on the forums - many people have this error, and on almost new cars with mileage starting from 4k

Chip tuning

Some drivers do chip tuning of the Chevrolet Niva in order to increase engine power. The essence of this procedure is to remove the established restrictions by adjusting the optimal factory settings in the electronic control unit. This procedure helps to extract the additional performance inherent in the motor.

The whole process can be divided into several stages:

The main advantage of this procedure is:

The disadvantages include:

Each specialist has a different attitude towards chip tuning, some consider it useful, while others think that this procedure can negatively affect the performance of the car, while reducing its service life.

Reasons that can cause a fire "Check engine"

One of the most harmless reasons for the appearance of a check on a Chevrolet Cruze is the use of low-grade fuel. Usually this problem manifests itself a few kilometers after visiting a gas station.

Refueling with low-octane gasoline leads to detonations when the air-fuel mixture ignites. The electronic control unit records this violation in engine operation and issues a command to the “Check engine” indication.

A low engine oil level or insufficient circulation as a result of a clogged filter leads to poor lubrication of friction units. This causes increased loads and excessive wear on motor components. If a malfunction is detected in the oil circuit, the ECU lights a check.

While stuck in a traffic jam, the power plant may overheat. The lack of cooling of the radiator by counter air flows leads to a rise in temperature above the optimal one.

To maintain stable operation of the power unit, the Chevrolet Cruze has a lot of sensors. Failure of any of them leads to incomplete information to the ECU, which makes it impossible to control the engine normally. The revs begin to fluctuate, the dynamics deteriorate, and fuel consumption increases. Very often the engine starts to stall. At the same time, the driver may notice the “check engine” light on the instrument panel.

If ESP OFF, slippery road and “Check engine” light is on, then a common cause is a dead battery. After charging it, it is usually not difficult to remove the illuminated indicators.

Tell me, which program is best to use to watch Cruise via elm usb?

What about the one on the screenshots that you’re not happy with?

I haven’t tried it yet, it seems to come with the scanner

What about the one on the screenshots that you’re not happy with?

Hello, are there any goodies that I can enable? for example, so that a key fob that has been wound up with a standard key can be closed with a button, otherwise in winter you have to turn the cylinder with a second key, and in general, some kind of adjustments and settings

Hello. No, just read the errors and watch the operation of the sensors responsible for the operation of the engine.

Hi all! Chevrolet Cruze 2012 The open door problem started. Everything is closed, but the alarm also shows when the standard alarm is turned on that the door is open. Is it possible, using the existing ELM327, to determine which door or trunk is fooling you?

It's unlikely to show. Most likely the limit switch is faulty on some door.

The elm cord doesn’t sew anything here, it’s only magicians who are lucky with the functions))

Well, I know Ford Sew Elm. How can I flash it with what adapters?

Ask in the community.

I also use this program. a good thing)

the adapter on the ELM327 does not see all errors, with its help we can only see what is transmitted via OBDII, and there is also a protocol that Chevrolet (GM) uses, and without a dealer scanner, according to my MDI, we will not be able to see anything (

This is true. I only need it for engine diagnostics, to see what sensors work, what errors are in the engine ECU. The rest doesn't interest me. Yes, and software for dealer scanners costs a lot of money, and, if memory serves, you can’t just buy it.
