Ошибка работы двигателя или АКПП P0600 автомобиля Audi

P0600 is a relatively uncommon OBD2 trouble code. It indicates that there’s been a communications failure between your Audi Q5’s ECM and one or more of the separate modules that it communicates with.

P0600 is a generic trouble code, so it has the same meaning for the Audi Q5 as it would any other vehicle.

Definition: P0600 Serial Communication Link

Your Audi Q5 uses a network of high-speed data wiring to connect modules to the ECM. Each module has a specific system that it controls. It’s commonly referred to as the BUS network.

How many modules your Q5 has depends on the model year and options that it has been equipped with. As a rule, the newer the vehicle, the more modules it’ll have. Here are some of the common modules that can be linked to the ECM:

• Ignition system
• TCM
• Traction Control
• ABS
• VVT
• Transmission Control
• Cruise
• Lane Assist/Road Departure
• Turbo Module
• Windows/Sunroof
• Airbags/Safety
• Body Control Module
• A/C

If ANY of them lose contact with the ECM, P0600 will be thrown, and the check engine light will come on.

P0600 Symptoms: Audi Q5

The symptoms of P0600 will depend on which module lost communication with the ECM.

For instance, if you have a transmission that isn’t shifting correctly, it’s fair to assume the transmission control module has lost communication. Airbag light? Inspect the airbag module and so on.

Before doing anything else, check to see if any other codes have appeared with P0600. They can give you a clue as to which module is faulty.

For example, if your Q5 has code P0300, which is ignition-related, start by checking the ignition module. P0700 indicates an issue with the transmission control module, and you’d want to look at the connection between it and the ECM.

If there are no other codes present, it’ll be tough to track down which module is causing the problem. When this is the situation (and even if it’s not), we recommend taking it to a mechanic with specialized diagnostic equipment to access the BUS system. They can make short work of diagnosing P0600.

P0600 is most likely caused by the following three conditions:

1. Module Connections

Check where the module in question connects to the wiring harness. Check to make sure that the pins are in good shape and corrosion-free. The module wiring will often run through one or more BUS junctions before finding its way to the ECM.

2. Ground

Your Audi Q5’s ECM, data BUS, and module in question both need a good ground to operate. Verify that it is in good working order.

3. Bad Module

If the module itself has gone bad and is not responsive, P0600 will be thrown. Wiring issues are more common than the module itself going bad.

Conclusion

The real problem with fixing P0600 in the Audi Q5 at home is that everything is so hard to get to (under the carpet, behind a panel, etc… ) We recommend taking it to a professional on this one (a very rare recommendation on this site).

• Двигатель не заводится
• Не правильно работает АКПП

Диагностика
ошибки P0600

• Первый шаг — это использования сканера для
  проверки наличия любых кодов неисправности, включая временные коды DTC.
• Для каждого кода необходимо
  проанализировать стоп-кадр, чтобы определить, в каких условиях автомобиль
  находился в момент появления ошибки.
• Все коды ошибок необходимо удалить, а
  после этого провести тестовую поездку для подтверждения симптомов.
• Затем необходимо провести визуальный
  осмотр на наличие поврежденных или изношенных компонентов.
• Необходимо проверить напряжение аккумуляторной
  батареи
• Используя мультиметр проверить
  целостность цепей питания и заземления блока управления.
• Провести тестирование блока управления
  двигателем в соответствии с рекомендацией производителя для этой ошибки. В
  зависимости от марки и модели автомобиля процедура может отличаться.

Частые ошибки
при диагностике кода P0600

Наиболее распространенная ошибка при диагностике – это неисправность
блока управления двигателя, хотя реальной причиной ошибки является «просаженный»
аккумулятор.

Всегда необходимо выполнять все этапы диагностики, в
правильном порядке, не пропуская никаких шагов, чтобы избежать неправильной
диагностики ошибки DTC P0600.

OBD-II Trouble Code Technical Description

What does that mean?

This is a generic powertrain diagnostic trouble code (DTC), which means it covers all makes/models, 1996-newer. However, specific troubleshooting steps will vary depending on the vehicle.

This code indicates a malfunction in the wiring link between the electronic control module (ECM) and one of its supporting control modules. On board diagnostics (OBD) trouble code P0600 is generic by design and encompasses all computer-controlled vehicles.

Explanation of OBD code P0600

Your vehicle’s ECM or powertrain control module (PCM) has lost its control over one or more actuator modules. Most vehicles have as many as 18 actuators that the primary ECM controls. It does so through a controller area network (Can Bus Automotive Network), which is a series of wiring harnesses from the ECM to the controllers.

The controllers operated by the ECM, known as modules, control the majority of the functions of your vehicle. The code P0600 was set when the ECM recognized a loss of communication and control over one or more of these modules for eight consecutive starts.

ECM and associated control modules

This is a list of the primary control modules operated by the ECM:

• Fuel injection system
• Ignition system
• Variable camshaft timing
• Turbo charger
• Emission systems
• Air conditioning
• Transmission shift points
• Body ride control
• ABS brakes
• Cruise control
• Anti-theft
• Sunroof and seat position
• Power windows
• Traction control systems
• Proximity alerts

These are just a few, not to mention all the available computer controlled options available today.

Symptoms

This is a commonly misdiagnosed code inasmuch as it may cause a deceptive symptom. Always bear in mind that the code P0600 indicates a communication failure. For instance — an ignition system failure or a failed fuel injector can cause a misfire.

An inexperienced technician may begin by attempting to diagnose the affected system rather than the loss of communication. If the ECM is not controlling the ignition control module or grounding the fuel injector, a misfire will occur.

This is not a fault with the system, but with control of the system itself. Depending on the location of the failure, the following symptoms may be present:

• Check engine light illuminated accompanied by an additional code,
• ABS light illuminated,
• Transmission light illuminated (vehicle may not shift properly),
• Big drop in fuel economy,
• Driveability problems may occur, such as stalling at an idle, rough running and poor acceleration, or
• Problems with a particular system indicating a possible communication loss in this area.

Potential Causes

Experience has proven that a poor connection or failed ECM driver is the root cause of this code. For the most part, the ECM acts as a ground to control these components and modules as opposed to supplying power to them.

A loose or corroded connector is more likely than a frayed or broken wire between both devices. Poor grounds are another plausible cause. The ECM, as well as the activator module, need a good ground to operate.

The wiring harness or Can Bus may be defective and have a short to ground or an open wire.

Diagnostic and Repair Procedures

The best advice concerning the diagnosis and repair of this particular code is to take the vehicle to a professional technician that has a Autohex or Tech II diagnostic computer.

If you unplug the ECM or the associated wiring and then probe the terminals, your bank account could suffer extreme consequences.

Most vehicles need to have a memory saver installed before disconnecting the battery to retain the ECM’s memory. Should the ECM lose its memory due to lack of power, the vehicle will not start until reprogrammed at the dealer.

Probing the wiring must be done systematically using the wiring diagram and pin values. If you probe the wrong terminal, the ECM and/or its associated module will be destroyed.

A competent technician will program your vehicle’s information into his Autohex or similar diagnostic computer in preparation to diagnose the P0600 code. He will then start the vehicle and monitor all the systems in real time. The tool shows the pin values and modules in operation and indicates any abnormalities. It’s an essential tool for diagnosing wiring or computer related problems without running the risk of damaging any components.

If you’re fortunate, symptoms or an additional code following code P0600 will steer you to the system in question experiencing the communication failure.

Upon identifying the system through symptoms or an additional code, check the connections for discrepancies such as loose or corroded terminals. A service manual with the wiring diagrams, pin values, locations of connectors, precautions and procedures are imperative.
