DTC error codes. DTC software disabling, DTC software deleting, Disable DTC error codes in the ECU. Description, destination, standards

In such a well-developed industry, like the automotive industry, fresh ideas appear infrequently, therefore this industry is not developing "up", but "styling", that is, not qualitatively, and quantitatively. Already about 40-50 years, nothing significantly new in engines internal combustion did not appear. The achievements of this millennium in engine technologies can be recognized perhaps that the possibility of riding poor mixtures in order to save fuel and appearance hybrid carsUsing along with internal combustion engines electric motors. However, these ideas themselves are 15-20 years old, it's just an opportunity to optimally distribute the mixtures in the combustion chamber of the serial car engines appeared relatively recently, and relatively compact batteries for hybrid systems have been created as much recently.

Today, all car experts are unanimous in the opinion that in the coming years up to 90% of new products in the automotive industry will have to be mainly on electronic, and not on mechanical systems.

Progress in the automotive electronics will also contribute to the fact that now there is some slowdown in consumption growth on the computer market, so many manufacturers of traditional hardware and software For computers, they switched their attention to the automotive market.

Electronic Automobile Systems (Drive-BY-WIRE)

Automotive control systems are moving from mechanical and hydraulic schemes to electrical and electronic. The new generation of automotive control systems was named X-BY-WIRE. Currently, such management schemes are very expensive, however, they are more reliable, occupy less space and ease of use.

The basis of future electronic automotive systems should be a reliable, sustainable communication protocols and devices that need high-speed reliable communication channels with predictable delay durations - this will be a key requirement in the automotive industry. Indeed, in the "electronic" cars, the mechanical connection between the driver, engine, wheels and even the brake pads will be replaced by electronic and electric, so the electronics requirements are extremely high here.

The most striking representatives of the new generation of automotive management systems of the X-BY-WIRE family are the SAFE-BY-WIRE security systems, in the development of which companies such as Analog Devices, Inc., AutoLIV, Inc., Delphi Corp., Key Safety Systems, Philips, Special Devices, Inc., TRW Automotive, as well as Bosch, Siemens VDO Automotive and Continental Temic (BST). These companies have established a new Association of SAFE-BY-WIRE Plus Consortium, which develops uniform standards for communicating security systems for motorists based on the consortium of experience and knowledge accumulated by participants in this area.

SAFE-BY-WIRE PLUS CONSORTIUM plans - Presentation of a prepared standard for consideration by the Working Group of the International Standardization Organization (ISO) for adoption as a global standard of systems automotive securitythat will have to change existing systems, including the dynamic stabilization systems common today car ESP. (Electronic Stability Program). The current stabilization systems are about ten, and they all differ in each other are ESC, VDC, VSC, DSC, DSTC, ATTS, etc., etc..

As for new protocols, then the situation has not fully cleared. The FlexRay Communication Protocol is gaining popularity (for the first time this technology is fully implemented on bMW car X5 second generation, which was published in 2007). Flexray controllers are imposed on the tasks of monitoring the engine, transmission, suspension, braking subsystems, steering and other side electronics - areas where the expansion of the functionality and the availability of developed diagnostic tools is in demand. FlexRay controllers are built on a two-channel architecture specifically for electromechanical management, such as Steer BY-WIRE (electronic steering, or Active Steering) and Brake-BY-WIRE (electronic brake control). The introduction of electromechanical schemes is the question of time, and should not even doubt that all the management in the nearest future cars will be completely digital.

Chain / System Description

The heater reduces the heater in the heated sensor (HO2S), the heater reduces the time required to warm the sensor to the operating temperature, and maintains this temperature at long periods of operation at idle. When the ignition is turned on, the ignition voltage is fed directly to the sensor heater. At first, when the sensors are cold, the ECM controller controls the operation of the heater, periodically closer control circuit on the "mass". Due to the control of the heating of the sensors, the probability of exposure to the thermal shock sensors is eliminated, which is possible due to deposits on condensate sensors. After the specified time expires, the ECM controller submits the command to the constant inclusion of heaters. After heating the sensor to the operating temperature, the ECM controller can periodically slow down the control circuit to the "mass", supporting the desired temperature.
The ECM controller controls the operation of the heater by earthing the control circuit using a semiconductor device, the so-called. Drivers. This device is equipped with a feedback chain that increases voltage. The ECM controller can determine the circuit of the control circuit, the short circuit to the ground or voltage, controlling the feedback voltage.

Fault diagnostic information

Before using this diagnostic procedure, check the diagnostic system.

Chain / System Description

Oxygen sensors with an electric heater are used to control fuel and control after the neutralizer. Each oxygen sensor compares the oxygen content in the surrounding air with an oxygen content in the exhaust. Oxygen sensor must have a operating temperature to issue right signal Voltage. The heating element inside the oxygen sensor (HO2S) reduces the time required to achieve the operating temperature of the sensor. The voltage is fed to the heater through the fuse along the ignition circuit. When the engine running, the heater mass is supplied according to the low level of the oxygen sensor heater (HO2S), through a low-level driver in the controller. From the controller, a command is issued to turn on and off the heater in order to maintain the temperature of the oxygen sensor (HO2S) in a specific range.
The controller determines the temperature by measuring the current flowing through the heater, and the resistance calculation. Based on the resistance in the controller, the temperature of the sensor is determined. To control the functioning of the heater in the sensors, a latitude and pulse modulation (PWM) is used. The controller calculates the resistance of the heater at a cold start of the engine. This diagnostic procedure is performed only once per ignition cycle. If the controller detects that the calculated heater resistance is outside the expected range of values, these malfunction codes are issued.

1. Turn off the ignition, disconnect the harness connector from the IAT sensor.

Important: To check the sensor outside the car, you can use a thermometer.

2. Check the IAT sensor, changing its temperature and simultaneously measuring the electrical resistance of the sensor. Compare results with the values \u200b\u200bshown in the table dependence of resistance from temperature. Inlet air sensor (IAT). Measured resistance should not differ from the required values \u200b\u200bof more than 5 percent.
If resistance is different by more than 5 percent, then the IAT sensor must be replaced.

Remove DTC, DPF BMW X5 E70 with EDC16 block

Loss of traction , Disconnecting the turbine, stalls the engine, errors over the gas emissions and the stuffing of the particulate filter are the symptoms that the replacement of the particulate filter is required. The first option is to buy an expensive component and change it, and the second is simply disabled it programmatically in the firmware. To disable it, this information will help you. The lesson consists of the original and modified BMW X5 E70 firmware. As well as the MAPPAK that, after downloading, will show you all the cards that you want to edit with already signed offpers and axes. More accurate information about the functions of the map and the necessary edits that you need to add you to be found in Mappaka. The kit consists of:

• Original BMW X5 E70 Firmware
• Modified firmware with remote DPF, DTC
• Mappak itself with a description of maps directly.

Also, consider that when removing the particulate filter, you need to remove the following errors: 4605 4606 4607 4608 Microfilter system 4030 4031 4032 4033 OG temperature sensor in front of the catalyst, signal 452a 452B 452C 452D System 4010 4011 4012 4013 OG reforts sensor in front of the microfilter, signal 4020 4021 4022 4023 OG temperature sensor in front of the microfiller, signal 4165 4166 4167 4168 4CF1 4CF2 4CF2 4CF2 4CF3 4CF3 4CF3 4CF3 System 41b3 41bc Signal Sensor 41ba 41BB 41BC 41BD OG 4D00 4D01 4D02 4D03 Sensor 4D00 Sensor 4625 4626 4627 4628 4D10 4D11 4D12 4D13 4D13 4D20 4D21 4D22 4D23 4D23 4D42 4D42 4D42 4D43 4175 4177 4177 4178 4175 4175 4177 4178 System summer filter, signal 4D70 4D71 4D72 4D73 microfilter system 4185 4186 4187 4188 OG temperature sensor in front of the catalyst, signal 4665 4666 4667 4668 System of the particulate filter
