Неисправна система 4х4 и DSC DBC активн руль отключён
После активной езды, через 40 мин Вышел завёл и на тебе гирлянда Неисправна система 4х4 и DSC DBC активн руль отключён но можете медленно продолжать движение до сто…
Печаль беда( завтра будем выяснять в чем дело.
Решение вопроса — прочитали ошибки
— блок активного руля не смог провести инициализацию мотора активного руля — из за низкого заряда акб!
— ошибки 4х4 и DSC DBC прошли после перекодировки автомата почему так пока вопрос… но видимо тоже из за севшего акб.
После кодировок и кручения рулем туда сюда все ошибки исчезли был произведен полет по объездной дороге за новым акб.
Основная проблема заключалась в севшем акб, а сел он как выясняется из за того что система не заряжает нормально пока гоняешь или стоишь на холостых заряд идет только когда мощность мотора не нужна те при поездке с круиз контролем на дальнее растояние или спуск с горы… так же для зарядки акб AGM нужен спец зарядник маленький такой с кнопкой AGM.
Поэтому после гонок я остудив масло на холостых ушел домой, а акб уставший работать с 2010 года пытался покинул этот мир)))
купил новый AGM акб прописал его и то его надо бы на зарядку поставить.
DTC BMW: что это?
DTC (Dynamic Traction Control) – это система динамического контроля тяги или «трекшен-контроль». Технология является частью комплекса DSC (Dynamic Stability Control) – системы курсовой устойчивости, которая используется на всех современных моделях BMW.
Активированный DTC позволяет ездить более агрессивно за счет частичного снятия ограничений на пробуксовку. Поскольку DTC снижает устойчивость авто, по умолчанию она отключена.
Подробнее о комплексе DTC
Из-за схожести аббревиатур, возникает путаница между назначением систем DSC и DTC. Система DSC ограничивает пробуксовку колес и предотвращает занос автомобиля. Например, если при выходе из поворота вы решили ускориться и одно из колес начинает пробуксовывать (быстрее вращаться), комплекс DSC ограничит мощность мотора или вращение самого колеса с помощью механического актуатора.
Возникает ощущение, будто автомобиль «мешает» водителю, едет «в натяг». Как только колесо перестает буксовать, комплекс отключается. DSC активируется самостоятельно – в это время на панели приборов начинает мигать красный треугольник.
Трекшен-контроль (DTC) обеспечивает более агрессивный режим езды при активной DSC. Суть в том, что при езде по рыхлым поверхностям незначительное проскальзывание колес может наоборот повысить их сцепление с дорогой. В этом случае активированный комплекс DTC позволяет добиться большей степени пробуксовки и снизить влияние системы DSC.
Когда нужно включать DTC
- Когда вы уверены в сцепных свойствах резины и хотите получить более полный контроль над машиной (например, на гоночном треке).
- Если вы решили «дрифтануть» — пустить авто в управляемый занос.
- Когда вы едете по снегу или грязи на небольшой скорости и хотите повысить сцепные свойства резины с поверхностью.
- При старте с места «враскачку».
Учтите, что активация DTC не означает автоматического отключения DSC. При активированном трекшен-контроле система DSC будет продолжать функционировать и в нужной ситуации вмешается в работу автомобиля.
Как отключить/включить DTC
- Комплекс активируется кратковременным нажатием на соответствующую кнопку (на приборной доске загорится желтый значок). При этом система DSC остается активной. В этом случае вы получите большую свободу действий и разрешите пробуксовку, но стабилизация будет все еще работать и пытаться не дать вам уйти в глубокий занос. Отключается трекшен-контроль также кратковременным нажатием кнопки.
- Чтобы отключить систему DSC, нужно немного подержать кнопку и затем отпустить. В итоге стабилизация отключится, а трекшен-контроль останется активным, то есть, машина будет «в полной боевой готовности».
Система DTC улучшает тягу автомобиля, но снижает его устойчивость на высоких скоростях, поэтому при включенном трекшен-контроле будьте предельно осторожны.

Troubleshooting BMW DBC Malfunction Problems
Is your BMW DBC (Dynamic Brake Control) malfunctioning? Know the causes of why the DBC is malfunctioning and learn possible solutions to fix the DBC by following the procedures below. Many newer BMW cars come with Dynamic Brake Control or DBC. This is an advanced active safety system that monitors and adjusts the braking power of each wheel. By doing so, it improves brake effectiveness, particularly in emergencies. When the driver needs to stop during an emergency, the system applies maximum braking power in a controlled manner to stop the car at the minimum distance. As this system controls the brake application electronically, it can offer useful additional features. One is Start-off assistance, which helps the driver start at the incline without pressing the brake.
Symptoms
If this system has a problem, a set of warning lights will alert the driver. In addition to the DBC malfunction message on the iDrive display, there will be several yellow warning lights on the dashboard and central display. In most cases, all of these will be related to the brake system. As a result of DBC issues, Start-off assistance stops will stop work, with Start-off assistance inactive message on the iDrive warning the driver. Lastly, the driver may notice that the braking feel and performance are different. The driver needs to adjust the driving style in such a situation.
What causes DBC Malfunction on a BMW?
- An internal fault within the ABS hydraulic module is the most common cause. In addition to disabling the DBC system, it can also affect both DSC( Dynamic Stability Control) and ABS systems. As this fault is quite frequent, many specialists can repair the module. This is a cheaper option than buying a new one and more reliable than installing a used module.
- A battery going bad and not holding the charge can cause electrical issues. In such a scenario, brake systems like DBC and DBS are the first to be affected. Checking the voltage on the battery terminals will reveal its condition. It is good to check the battery terminal for dirt or corrosion, which can have the same effect as a bad battery.
- Like a bad battery, a dying alternatorcan cause various electrical systems to act unusually. DBC and DSC are very sensitive to voltage, so they are easily affected.
- Steering angle sensor. A piece of important information for this system is the steering wheel’s angle, as it needs to know if the car is turning or going straight. A steering angle sensor provides this data; if it fails, the DBC system will go off. In some cases, the misalignment of the wheels can have the same effect.
- A faulty wheel speed sensor will bring down all brake assist-related systems, as they all need information about wheel speed. In practice, rear sensors are more likely to fail. Check the wiring and the connector before replacing the sensor. After removing the sensor, check it for damage in the frontal area. If there are any scuff marks, the ring is either rusted or bent out of shape. A ring of this type must be replaced, as it can damage the new sensor.
The YOUCANIC Full System Scanner can read and clear fault codes through every control module on a vehicle.

Что такое dbc bmw x6
While driving down the highway the car jerked suddenly and the following malfunction lights came on:
«Chassis stabilization malfunction»
«DSC and xDrive malfunction» — Chassis stabilization and traction reduced. Drive moderately. Have the system checked by the nearest BMW center.
«DBC malfunction! Drive carefully»
After the warning lights came on, the car of course drove in limp mode until I got home (thankfully 1mile away). After parking the truck and restarting the error lights went away and oddly drives normally as if nothing happened.
Has anyone had this problem? I searched around a found several pre-2010 5-series owners having this issue with the cause being a faulty steering position sensor.
I have a 2010 X5M w/11k miles and it hash’t been serviced/been to a dealership since the purchase last Nov.
Aside from this error, I did get the «power reduced error» once after hitting the rev limiter in 1st which went away after restarting.
Also on a few occasions, normally on my way home in traffic, I’ve noticed the engine would sometimes emit a large amount of white smoke after some stop and go traffic, or when up-shifting under light/moderate load. I’ve asked ESS and they never heard of this issue.
The truck has Akrapovic downpipes, SS catless downpipes, ESS reflash and K&N filters. I’m debating bring it in to the dealership, however I’m hesitant given the downpipes and reflash (very noticible). Any ideas?

My X3 did this back in February. They needed to replace the transfer case.

Its been about a month and a ~1000 miles worth of driving and I haven’t had the issue reoccur. Since I’m due for my 1-year service and the upcoming water pump recall I’ll have the dealership check the system, however I’ll probably remove the downpipes and software first (leaving the exhaust on). Does anyone know if flashing back to the factory software will reset the trouble code memory?

Sorry to derail the thread.
How do you like the Downpipes, and did you install them after the Akra or at the same time?

I installed the downpipes about a month after I installed the Akrapovic exhaust, and installed the software about a month before I installed the exhaust.
I felt the biggest performance impact from the downpipes and downpipe reflash.
ESS 91 octane software only: The truck felt much stronger off the line and in the mid-rpm range. The upper rpm range felt similar to stock. The shifts were also slightly better. Spending roughly 2k is worth it.
ESS 91 octane Software + Akrapovic exhaust: The truck felt exactly the same, no noticeable improvement in performance. The cold start was slightly louder, and while driving, the truck had a slightly louder sound though it�s almost indistinguishable from inside. The shifts did have a slightly better pop, and the truck did feel slightly more nimble from the decent weight reduction. Personally I wouldn’t pay 6k for this exhaust and expect a noticeable performance impact or significant change in sound (from inside the truck). If you look at the stock exhaust you�ll understand why its not much of a restriction.
ESS 91octane downpipe software + Akrapovic exhaust + SS downpipes: The truck felt MUCH stronger and MUCH louder. The difference is stunning. The entire rpm range feels significantly stronger and the response after shifting seems much quicker, probably due to the decrease in backpressure. On cold start the truck is VERY loud. So loud that it will sound as if a race car started (and this is coming from someone who drag races 1200hp turbocharged cars). Spending 2k on downpipes is stupid, though the difference (with software) is great. A cost effective solution is only doing software and catless downpipes, though some said the exhaust sounds strange. Depending on what downpipes you get, I bet you can do software and downpipes for under 3k. Much better than the 10k setup I have, and will have similar performance to what I got, and while retaining the stock look.
In normal mode and under normal throttle conditions the truck is louder than stock and emits a faint turbo whistle in the lower rpms. On occasion I do get some slight turbo surging (typically from heat soak after being in traffic) and mild on/off throttle hesitation, typical on factory turbo cars with similar mods. Only under full throttle (when the exhaust valves open) does the truck get very loud. Also the manual shifting in normal mode feels very sluggish and actually makes a louder and longer burble sound when shifting.
In sport mode (exhaust valves always open) the truck feels very responsive and the shifting is crisp. Manual mode feels great and has a great quick pop sound. You’ll also notice a stronger smell of gas/exhaust fumes in this mode as a result of the outer exhaust tips bypassing the muffler.
In M-mode (all vehicle settings set to max performance): the truck feels great. Very responsive, quick shifts, great exhaust notes, VERY loud, and very twitchy in traffic.
General Downsides:
— You will get a strong smell of gas/exhaust fumes while driving in traffic, sitting at stop lights or during cold start or after a quick pull through the gears. I’ve actually had a few people pull next to me and complain while in traffic (though it�s the SF Bay Area, CA so I’m surprised).
— From time to time I do get traces of detonation during partial throttle in lower rpms (exhaust is too loud to hear it in the upper rpm range).
— On a few occasions I’ve noticed the truck emit plumes of white smoke (smells like oil) during normal acceleration/shifting after slowing down in the highway. No idea why this happens or why it rarely happens and it�s not repeatable.
— I did have one engine malfunction error after hitting the rpm limiter in first gear under full throttle. After restarting the error went away and I’ve never had it happen in the past 5,000 miles).
— I had the error described in this thread, however I’ve been unable to neither replicate it, nor do I know the cause. Unfortunately I’ll need to remove the downpipes and reflash back to stock (leaving the exhaust) to avoid dealership issues.
— The downpipe install is not fun. I did it myself (very experienced and have the correct tools) which took 2.5hrs. A normal user would have great difficulty doing this. Most shops would charge a ~5-8hrs for this job (350-1000 in labor depending on the rate)
