Car SSANGYONG NEW ACTYON/KORANDO C Year 2013 2.0 D20DTI

According to the client, the car in motion periodically began to "stupid" and did not respond to the gas pedal. During the movement, the failure manifested itself repeatedly. The car then drove normally, then how it rested against the wall.

The scanner gave the following errors:
Troubleshooting codes
P0633 (00) Immobilizer (defective)
P0671 (00) Glow plug Cylinder 3 - open in the chain
P0672 (00) Glow plug Cylinder 4 - open in the chain
P0674 (00) Glow plug Cylinder 1 - open in the chain
P1124 (00) Accelerator pedal position malfunction stuck

Errors P0633, P0671, P0672, P0674 are not related to the problem reported by the client. We postpone work on these errors for the future. The only error indicating a customer complaint is P1124 (00) Accelerator pedal position malfunction stuck.

This error directly points to a possible source of malfunction - Accelerator pedal position. The pedal position sensor, the wiring between the pedal position sensor and the control module (ECM), the engine control module (ECM) itself, and there may also be external factors affecting the engine control module (ECM) may be faulty. When checking on the spot in the service on a running car, the failure does not appear in any way. The motor responds to the gas pedal, error P1124 is not set. Needs to be checked on the move.

Recording parameters
1. engine speed
2. speed sensor
3.pedal position switch
4.pedal position switch N1
5.pedal position switch N2

Here is a screen (below) where the failure does not appear, and the car responds to the pedal. pedal position switch N1- 28.22% pedal position switch N2- 27.84% pedal position switch- 28.01%

And literally after a few seconds, the ECM, in the presence of signals pedal position switch N1-26.27% and pedal position switch N2 - 26.27%, sets the total calculated signal pedal position switch-0%

It is not clear why, with a time difference of several seconds, the DCM3.7 engine control unit sets the pedal position switch parameter to the corresponding signals of the pedal position switch N1, N2, then ignores these signals and determines the pedal position switch-0%.

Perhaps some interference interferes with the signals of the pedal position switch N1, N2. To test this version, the Autoscope 4 was connected to the signal connection points of the pedal position switch N1,N2 on the DCM3.7 connector. An oscillogram was recorded while driving during the manifestation of a malfunction in the engine:

The oscillogram shows that both signals of the pedal position switch N1, N2 do not have noise and interference. The voltages of pedal position switch N1 and pedal position switch N2 differ by approximately 2 times over the entire operating range.

Based on the signal received using the Autoscope, we can conclude that the pedal position sensor and the wiring from the pedal to the control unit are working. So there is external factor, causing the ECM to set the calculated pedal position switch to -0% if the correct pedal position switch N1, N2 signals are present.

Scanning all systems did not reveal any errors. Further, it became clear that in order to solve the problem, it was necessary to delve into the mangrove jungle of the non-linear logic of Kim Il Sung's falcons, which is fraught with irreversible changes in the cerebral cortex. And it may end with a fun trip with orderlies to Kashchenko. The prospect did not inspire. It was decided to shift the heaviest on someone else's shoulders. Through a friend, I got the phone number of an electrician from the SSANG-YONG dealership. This courageous man at first could not understand for a long time what they wanted from him. Understanding, he said that he did not have such a thing. Maybe it really wasn’t, or maybe it was, but he didn’t speak. Or maybe he just didn't want to get out. cozy nest in banyan roots. But as they write in the detectives, "the investigation has reached a dead end." And I climbed into the car and began to thoughtlessly examine the buttons and light bulbs in the hope of unexpected inspiration. And indeed, some accidentally lost Pegasus still kicked me with his hoof. And I pressed the brake pedal, while asking a mechanic who ran past to see if all the brake lights were on. He confirmed that everything is on fire. The DCM3.7 connection diagram shows that a brake pedal sensor is connected to the ECM, which can affect the calculated parameter of the pedal position switch

Checking the brake pedal sensor showed its serviceability. However, it suddenly turned out that when you press the brake pedal, along with the stop signals, the side signals also light up. And, conversely, when the interior light was turned on, the stop signals came on. Here it is! Eureka! Next is the matter of technology. The reason for this work was the short circuit inside the double-helix light bulb "gauge-stop", which caused the malfunction. Movement by the rules traffic carried out with the included headlights and parking lights. Through the closed spiral of the "gauge-stop" light bulb, a signal came to the DCM3.7 about the supposedly pressed brake pedal. At the same time, when Accelerator pedal position was pressed, the ECM took it for a false signal, set the error P1124 (00) Accelerator pedal position malfunction stuck and limited the movement, taking the calculated parameter pedal position switch-0%. No other errors were recorded in all the car's ECUs, which greatly complicated the search.

Very soon I was holding in my hand a two-coil light bulb, closed inside between the coils. Replacing this key part miraculously brought the gas pedal position readings back to normal. And strengthened my confidence in the invincibility of the great sons of Kim.

Many compatriots were very happy to see a line of cars from the Korean SsangYong on the Russian market. Still: you can take “for a million” an off-road SUV in full stuffing, with a factory warranty, and other reflections of gloss that overshadow your eyes. The reality turned out to be a little less rosy, and the attitude towards these Korean cars among the owners, in general, is ambiguous. And not everything in them is treated by the direct hands of the service and service stations - let's figure out why.

Are you having problems with your SsangYong?

This is not an SUV

The lineup of the Korean - and these are Kyron, Rexton, Aktion and exotic Nomad and Stavik - tell us with their appearance: "look, I'm a big off-road car." Straight "Jeep part-time". This is not true. Not at all. The entire model range in the basic condition - in best case, urban and family cars.

All SY Koreans don't have that much power output from the engine. Driving over 90 km / h on the highway becomes a problem: the dynamics do not allow you to convincingly overtake, speeding up to 110-120 and beyond is reluctant. We do not recommend driving at speeds of 130-140 at all, which will be discussed later.

An attempt to use the SY as a real SUV will end very quickly before it starts: there is no mechanical strength in the nodes of this car. Base and turning radius - not for rough terrain at all. Off-road dynamics leave much to be desired, and the cost of subsequent repairs will finally convince the owner that the idea was so-so.

To call on the curb, or to dig out of the snow can. But don't expect more from them.

Half of the problems and unfulfilled expectations stem from inconsistency appearance and inner possibility. But not only. Let's go down the list.

Common faults

Weak suspension

Every second owner complains about the Korean suspension. In short, it is too hard and rough to handle, and too soft to break through. It is connected with design features bridges and structures, nothing can be done about it. On models recent years the manufacturer (having drawn conclusions on the repair) puts reinforced components, but this does not fundamentally change the sensations.

Optics

Almost every SY from the salon is blind. But everything is simple here, the lamps are changed to normal, something can be “twisted”. If you do not think about it in advance, at dusk, generic blindness can be unpleasantly surprising.

exchange rate stability

A sore point of all the first generations of Koreans SY. Partly due to weight distribution - their center of mass is higher than we are used to, partly - with the properties of the suspension. SsangYong has malfunctions here in bulk.

Every second review on the forums in 2010-2013 looked like this: “I’m driving along the highway, I don’t touch anyone, oops! - and the car flies somewhere.

The manufacturer made conclusions as far as he could. But the sediment remained. The car behaves strangely and illogically. According to the owners, the situation could be corrected by all-wheel drive, but it does not work at track speeds. The propensity to fail fasteners only adds to the ambiguity.

The fact that the height and weight distribution is to blame is evidenced by the fact that the updated Rexton - which is lower and squat - almost got rid of these generic problems.

For long trips along the highway, cars are not very well adapted in terms of comfort. The car does not let you relax, there is no cruise control. Not a UAZ, of course, but an experience for an amateur.

Winter

With the winter, the Koreans are bad. At temperatures below -10, get ready to run with anti-freezes, find out “why it doesn’t start” and go to the service on a tow truck.

ball joints

The unsuccessful constructive element of the first generations of SY also did not add positive emotions to the owners. Ball joints flew out of the mounts on the go, for no apparent reason, the car was in a ditch, it's good if people are alive.

This is a factory defect, a replacement under warranty, but the replacement was somehow sluggish: there are still a lot of Koreans in the secondary market, where no one has changed anything, and the SsangYong malfunctions have remained.

With other mechanical fasteners, the load-bearing parts of SY cars also show problems. Either dynamic loads were poorly calculated, or simply the quality of welding. But there is a risk that some necessary part will fall off at an unnecessary moment. Gentlemen, but this is not a UAZ, in fact.

nozzles

If a Korean has nozzles flowing, then they flow with soul, entirely and for all the money.

Solved by replacing injectors. It appears after 30-35 thousand kilometers. Breakdowns are not recognized as factory defects, they are just the way they are. Some configurations are lucky, and all is well. Patterns have not yet been identified.

automatic transmission

The Chirons are diagnosed with a factory defect with the control board in the automatic transmission. Changed under warranty. But there is quite a lot of fuss. It usually appears after 40 thousand, in recent generations promised to fix it.

Suspension again

The manufacturer did not work out with the rear axles. Especially if the owner considered his car an SUV, and after 40-45 thousand. And everything would be fine, but there are absolutely not enough new complete bridges for the whole of Russia, and you have to wait months for a spare part, telling friends and neighbors that the Koreans are so-so under repair.

fatal 50 thousand

Let's face it. By their 50,000 run, the Koreans begin to crumble, and in significant parts, and at the risk to the owner.

On the other hand, the price tag of the Korean is such that it allows you to take exactly the new SsangYong, instead of the used Japanese. And "to sell at 50". The only problem is that then everyone who has lived to the point of no return is trying to sell.

To take or not to take?

If it's about new car- why not. If you understand the limitations of the Korean line, and do not demand the impossible from the car. In fact, this is a city and family, sometimes country car, which occasionally - occasionally! – can manifest itself as an SUV.

If it's about secondary market then think twice. Possible problems, which did not appear in the previous owner, and are waiting for you, this car is not at all cosmetic. Repair SsangYong business is not cheap. At the same time, a Korean does not repair with a “sledgehammer and a band-aid” like an UAZ or old Japanese, and you risk collecting patch repairs from a car with all possible uncertainty.

If you have already have a koreanSY- now you know the possible places of "generic" problems. This, by the way, does not mean that everything else will not fall apart. But at the service station, pay attention to these nodes. If your vehicle does not have defective blocks replaced, consider replacing as soon as possible.

SsangYong New Actyon is offered with two types of 2-liter powertrains: 149 hp petrol. and diesel 149 hp Initially, the diesel was offered in two variations - 149 hp. and 175 hp

The gasoline engine received a number of complaints. Many owners periodically notice a rattling or a short “growl” when starting a cold engine. Extraneous sounds are not “born” every time the engine is started and can occur both on new cars and those that have been in operation for some time.

Another more serious drawback is the "winter start": the speed floats, and the engine stalls immediately after starting or after some time. The manufacturer tried to solve the problem by correcting the engine control program. But this method did not help everyone. Some auto mechanics suggested that the cause of the troubles lies in the wrong angle of the fuel rail: air leakage and “sweating” near the nozzles were noticed. " folk method» - bend the ramp and change the sealing rings. According to the owners who made such a revision, the engine began to run softer, and the speed stopped floating.

The diesel engine periodically causes inconvenience due to the short resource of the exhaust gas temperature sensor on the turbocharger: “Check” lights up, traction drops, cruise control does not turn on. The sensor resource is 20-40 thousand km, although there are many owners who have traveled more than 50 thousand km without problems. Dealers replace a faulty sensor under warranty. The cost of the sensor at the "officials" is about 5-6 thousand rubles, in the spare parts store - about 3-5 thousand rubles.

The engines are paired with 6-speed manual and automatic transmissions.

Owners of New Actyon with a manual transmission note a tight engagement of 1st and 2nd gears, accompanied by a knock or crunch. After several tens of thousands of kilometers, the problem usually goes away. Individual owners got rid of the disadvantage by adjusting the shift lever thrust.

On diesel versions of New Aktion, an “automatic” of Australian origin DSI M78 AT was installed. Many note the appearance of jolts when the box moves from 1st to 2nd or after stopping, less often when moving 2-3. The manufacturer tried to solve the problem by changing the firmware of the box ECU, but the update does not help everyone. When trying to change the working fluid in the box, it was found that the conveyor was underfilled from 0.5 to 1.5 liters of the transmission. Unfortunately, changing the fluid and bringing its level back to normal did not solve the problem of jolts.

Gasoline versions are equipped with a Hyundai automatic, which is installed on a potential competitor - the ix35 crossover. There are no problems with this box.

Some owners make claims against the all-wheel drive system, finding the operation of the system untimely. But there are no errors in the system, and real cases failure was not found.

The front suspension of the SsangYong New Actyon often begins to knock already in the first ten thousand kilometers. There is no panacea: some specimens were helped by tightening the nuts for fastening the supports of the front struts, others by tightening the central nut on the shock absorber rod. Replacing the bearings does not solve the problem. The rest resigned themselves and drive, not paying attention to the periodic knocks in the suspension.

When inspecting the chassis with a run of more than 20-40 thousand km, a rupture of the anther of the outer CV joint of the front axle shaft is often found. The cost of a new boot at dealers is about 1.5-2 thousand rubles, in the online store 1-1.5 thousand rubles. Some owners with a run of more than 30-50 thousand km were faced with the need to replace a buzzing front wheel bearing. Sometimes, when examining the suspension, the destruction of the rear stabilizer bracket is revealed, it is also the bracket-holder of the rear stabilizer bushing.

Some owners of Actyon note the appearance of a crunch or clicks when turning the steering wheel from the extreme position to the opposite. The warranty replacement of the lower part of the steering shaft assembly with the EUR solved the problem. The cost of the node is about 70-75 thousand rubles.

Body iron and painting quality is traditional for modern cars. Metal in places of chips blooms in a couple of days. Over time, chips appear on the rear fenders at the upper points of the rear lights. Probable Cause– Excessive mobility of the tailgate with a diagonal load. Chrome-plated body trim elements become cloudy after a couple of winters and sometimes begin to swell, especially on the nameplates and the tailgate trim.

Cracking of the upper brake light is often found. Most likely, the lantern overheats, which indirectly confirms the deterioration of the spray of the rear washer nozzle built into the lantern - the water boils. In winter, when the liquid poured into the washer freezes, it squeezes out the front washer nozzles from the seats. The cost of a set of nozzles is about 400 rubles.

Often there are problems with power windows, more often the rear ones: at first they work every other time, and then they completely stop responding. Authorized services replace the electric motors of the drive under warranty (about 3 thousand rubles). Possible reason malfunctions - insufficient lubrication in the rollers and pinched guides, as a result, the electric motor cannot withstand a constant heavy load.

Plastic in the cabin often creaks, especially with the advent of cold weather. The backlash of the glove compartment hinge makes its contribution to the accompaniment on bumps. After the first ten thousand kilometers, the steering wheel cover often begins to peel off. Unfortunately, not all dealers go to meet the client and change the “balding” steering wheel under warranty.

Not without a couple of "glitches" of electrical systems. One of them, disable cruise control. The reason is described at the very beginning of the article - the failure of the exhaust gas temperature sensor on the turbocharger.

The other is found on Aktion equipped with ESP. Owners are faced with the flashing of a “garland” of ESP + ABS + handbrake signaling device, which is sometimes “seasoned” with EUR malfunction signaling devices and the “Check AWD” all-wheel drive system. The illumination of the scoreboard, as a rule, occurs immediately after working out the ESP in the winter on ice, more often on an uneven surface. It should be noted that this situation does not occur every time the system is triggered. After turning off the ignition, the "glitch" goes away, and the system continues to operate normally. Solutions to the problem and explanations of the nature of the origin of the "phenomenon" from dealers on this moment no.
