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

Meaning	Translation	What to do
Change Engine Oil Soon	The time to change the engine oil is approaching (less than 5% service life)	Fill the oil and reset the readings of this resource
Low Engine Oil Level	Low engine oil level	If after filling the oil the message does not disappear, then let the power unit operate in the thermodynamic cycle, because instrument cluster is ok
Oil Pressure Low – Stop Engine	Low engine oil pressure - stop the engine	Bringing the indicator into line
Program Cluster	Program the instrument cluster	Performed after replacing devices or when information appears on the display. the center of such a message. We recommend carrying it out using the SPS system
Service Vehicle Soon	The next vehicle maintenance is approaching	The error is displayed when a problem is detected by the ECM engine control unit

Do-it-yourself code 95 Chevrolet Cruze error reset

So how can you reset errors on a Chevrolet Cruze yourself? The article is the final one in a series of my experiments on reading and resetting Chevrolet Cruze airbag errors.

I no longer believed in the possibility of self-resetting with Chinese devices when I received a parcel at the post office with another car scanner. The seller promised that this scanner would clear errors on my car (just like the previous one).

I'll tell you a little about the parcel itself. It reached me in about two weeks, delivery was fast, as promised by the seller. The packaging is not wrinkled, which was surprising; nothing inside was damaged. The disc downloaded to the computer quickly, without problems, there was an activator on the disc, video instructions in the application, everything was great. Everything was perfect, it really alarmed me, well, the Chinese don’t have jokes.

Having connected the scanner to the car, it lit up with light blue lights as expected, the drivers installed without problems (available on the disk), after installing the drivers, the lights changed to dark blue. After starting the program, the scanner was normally detected by the computer, I was informed that the scanner software was out of date, by clicking on the button in the program I updated it.

ATTENTION! The software update in the scanner occurs only when the cable is connected to the computer; it is not done over the air, because the Bluetooth module is turned off during the firmware update. During the firmware installation, the scanner lights up and flashes red lights; you should not remove the voltage from it unless you want to get a “brick” instead of an expensive device. After the firmware it glows either blue or dark blue.

The program menu contains a Chevrolet Cruze, I chose 2012, the blocks were diagnosed. And most importantly, the scanner found the SRS unit, read the airbag errors, found a crash record (this is a record that appeared during a collision in the SRS controller, which does not allow a pregnant man to disappear). With a trembling hand, I pressed the error erase button, the scanner began to click the switches, at that moment I expected anything from an error message to the shooting of the surviving airbags (in the seats and doors). And then it happened! The scanner erased the errors and the pregnant man on the instrument panel went OFF!

After gawking a little at the dashboard and the disappearing “Code 95” error message, I decided to turn off the car and turn off the ignition. After turning on the ignition and turning on the car engine, the error did not appear. At this moment I thought that it couldn’t be that I guessed correctly with the resistances of the decoys and the most important thing is that all these resistances have normal contact (I didn’t solder) and the shock sensor was not damaged, because I installed the original sensor in place , into the standard connector. I turned off the ignition again and started the car again, but again nothing, everything works fine.

To experiment with the ignition off, I removed the trick from the belt pretensioner, turned on the ignition, error 95 immediately appeared on the panel, after connecting the trick with the ignition off and turning on the car, the error no longer appeared.

After reading the airbag unit with a scanner, I found an error about the missing connection between the belt pretensioner and the controller. Everything works, I'm amazed!

I described the connection of decoys in the article “Installing decoys”

I recommend! The scanner comes with a 4 GB memory card.

Code 84

This error is a little more complicated. It indicates a problem with the engine and its transition to emergency mode. Essentially, it means that the motor is running only to get to the service on its own. It is not recommended to drive for a long time with error code 84 illuminated. This can lead to serious damage. There may be several reasons for this code:

Lack of coolant. The problem is related to the pipes passing through the throttle. When they overheat, an error may appear. After adding liquid, this code may disappear. This is perhaps the simplest fault;

Check the condition of the throttle valve. When using bad fuel, various blockages can occur. However, it may not close completely. In this case, the control unit sees changes in the angle. As a result, it shows this error. If contamination is detected, be sure to clean the throttle;

Another problem also arises from the throttle valve. It's electronic on the Cruze, and that's where problems arise. Under the side cover there are 4 contacts and 4 tracks. The center contact often wears out. In this case, it turns out that the contact does not reach the track. This is treated with tweezers. With its help, the contact is pressed to the track. True, the effect of such repairs does not last long. Soon you will still have to change the throttle. To do this you need to buy it assembled. Parts for it are not sold separately;

The gas pedal can also cause this error. On the Chevrolet Cruze, the accelerator also has a block similar to that installed on the throttle valve. The reasons for their failure are the same;

Electronic control unit. Oxidation of the contacts on it often occurs. You should pay attention to contacts 42 to 46. After inspecting them, clean those contacts that are covered with green oxides.

These are the most basic reasons for the occurrence of codes 84 and 89. But sometimes they light up due to problems with the software of the control unit. If, after checking all possible options for the error, you cannot find the source, then most likely it is a block glitch. In this case, it is necessary to reflash the unit. This should only be trusted to an experienced craftsman familiar with this work. In this case, you should only use the original program.

Errors 84 and 89 on Chevrolet Cruze: what they mean and how to get rid of them

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 corresponding problems that need to be eliminated in order for the engine to operate in standard mode again.

Chevrolet Cruze: error code 89

All owners of a Chevrolet Cruze 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:

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;

Next, you need to go purchase consumables: oil, filters, and so on;
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:

Problems with the throttle valve. Chevrolet Cruze vehicles are equipped with electronic throttle. The following problems most often arise with it:

When reporting an error, the electronic control unit stores it in memory, which may negatively affect its operation in the future. It is recommended to reset errors after fixing the problem. To do this, disconnect the battery terminals for a few seconds and connect them again.

How does a mechanic diagnose a P0136 code?

When diagnosing this error, the mechanic will do the following:

Reads all stored data and error codes using an OBD-II scanner, clears the error codes from the computer's memory, and test drives the vehicle to see if the P0136 code appears again
Observes real-time oxygen sensor readings using a scanner to determine if the sensor is working properly
Check the electrical wires and oxygen sensor connector for corrosion and damage
Measure the resistance in the oxygen sensor heater circuit and compare the value obtained with the value specified in the manufacturer's specifications
Check the exhaust system for exhaust gas leaks
If no problem is found, continue diagnosis following the procedure established by the vehicle manufacturer

Chevrolet Cruze dashboard not working

Device fuse installed under the panel.
Contact groups and module wiring.
If all structural elements are in order, you should check the device itself.

The dash doesn't light up

The wiring and connection diagram of the panel is checked in the same way if the backlight disappears.

Cruise's dash is blinking

Panel malfunction is often caused by loose contacts on the terminal blocks. It is necessary to disassemble and clean the elements from oxides, possible plaque or rust.

Also, the reason for the blinking of the tidy can be loosening of the contact groups and weakening of their pressure. To fix the problem, you need to replace the pads.

Cruz: the starter does not turn and the tidy goes out

Check battery charge. This is a clear sign that the battery is hopelessly dead.

To eliminate the problem of voltage drop when turning the key, just charge the battery or replace it with a working one.

Other faults

Error code 89 Frequently encountered problems that prevent the engine from starting and methods for troubleshooting Chevrolet Cruze with 1.6 and 1.8 engines are summarized in the table below.

Malfunction	Description
The gear selector is incorrectly installed	The ECU of cars with an automatic transmission controls the position of the gear selector lever. Starting is not possible if one of the movement options is selected. Moving the gearbox to the “P” position will eliminate the impossibility of starting. Cars with manual transmissions do not have this problem.
Code 89	In most cases, it reports a thermostat malfunction. Code 89 rarely becomes the reason for the inability to start the engine, but with a combination of other faults, it can prevent the car from starting. To fix the problem, you need to replace the thermostat.
After washing the car stalled and would not start. Sometimes the engine seizes.	Dry the engine compartment. If necessary, replace the air filter.
