What the process of ECU diagnosis and program

Saturday, September 23, 2017 2:58:31 AM America/Los_Angeles

ECU diagnosis often when the program to brush out the ECU, the general non-developers are using the diagnostic brush program. Some can use the ECU vendor to provide a small software brush program. Because the application environment is different, maintenance personnel brush procedures need to consider more permissions and stability requirements, then talk about the use of diagnostic brush program, the diagnostic apparatus which services are called. This is the default using UDS diagnostic protocol. The Flash process here is common to all ECUs.

Flash process
1. Change the ECU status to the extended state; call Session Control = Extended Session

2. Read the ECU ID information, check the hardware information and the old software version number; call Read Data by Identify

3. Check whether the conditions of the brush ECU are ready, such as whether the engine is off; call the written Routine

4. Close the DTC service; call Control DTC Setting = off

5. Turn off CAN communication; call Comunication Control

6. Change the ECU status to start programming; call Session Control = Start Programm

7. Diagnostic instrument authorization; call Security Assess

8. Update the history, record the time and success of each brush program; call Write Data by ID-Write Fingerprint

9. Download the first part of the driver to remove the software; call Request Download

10. Delete the old software; call Routine

11. Download the second part of the driver for downloading new software; call Request Download

12. Download the new software; call Request Download

13. Verify that the software is authorized; call Routine

14. Check the software is complete; call Routine

15. Set the parameter variable, usually according to the old software parameters; call Write Data by Identify

16. Restart the ECU; call ECU Reset

17. Reboot CAN communication; call Communication Control

18. Restart the DTC service; call Control DTC

19. End of diagnosis, change the ECU as the default state; call Session Control = default Session

Above for the entire brush ECU process, hoping to let everyone understand the UDS service specifically what is the meaning and how the application in the diagnostic process.

What is Injector code , and why code injectors

Thursday, July 6, 2017 4:01:52 AM America/Los_Angeles

What is Injector code , and why code injectors

To code or not to code that is the question…..?

 In days gone by, diesel injectors although cumbersome to fit, were generally seen as plug and play. However, since the advent of common rail diesel systems, and in turn common rail injectors, the garage can often be left confused or unsure as to whether an Injector needs coding or not. 

Common rail diesel systems offers a number of benefits over traditional diesel systems, such as improved performance, lowered fuel consumption and quieter engines. Another significant advantage of a common rail system is its ability to uniquely reduce emissions, the buzz word on the lips of every Eurocrat.  

So why code injectors? An injector code, typically known as an IMA code (Bosch and Siemens) or a calibration code (Delphi), is a code that is programmed to the ECU for accurate communication and Injection control. With ever increasing emissions legislation and tightening of limits, vehicle manufacturers have been forced to more accurately control the flow of fuel going into the engine to optimize the efficiency of the combustion process and control emissions within acceptable limits... 

The IMA coding is an industry standard: Injector Menge Abgleichung (injector Quantity Offset). When an injector goes through the OE test it generates an IMA code which identifies where in the tolerance range the needle and nozzle assembly fit, this allows the ECU to vary the fueling accordingly and optimize the engine performance. Failure to code in the injectors can result in several issues:

  • Performance – In some systems it may be possible to drive away and not notice any difference. In reality, if the injectors have not been coded, it is unlikely that the customer will be getting the optimum performance from the vehicle and may well end up back at the garage with an increase in fuel consumption or black smoke etc.
  • Non start – In newer systems if you do not code in the injectors the vehicle will not start
  • Poor / lumpy running – as the injectors are not coded, the ECU will carry on fueling as if the previous injector was still present, which can cause poor performance. The engine management light is also likely to come on   necessitating another visit to the garage.  


How do I know if the injector I have purchased needs coding?

 DELPHI Common Rail Injectors – All require coding to the engine. Typical code is 16 alphanumeric characters (C2i Injectors) or 20 characters for more recent applications (C3i injectors). Code typically found on Injector head.  

DENSO Common Rail Injectors – As a rule, all require coding, although some very early releases may not. Typical code length is 16-24 alphanumeric characters dependent upon vehicle marquee. Code typically found on Injector head. You can also use the QR code found on the injector for this information.  

VDO/Siemens Common Rail Injectors Injector’s – Only VW applications at this moment require coding. Typical length is 6 digits and found on the injector head. 

BOSCH Common Rail Injectors – As a rule all require coding, although some earlier releases may not, in simple terms if an IMA code is present then the injector will need coding. Typical length of code is 6-10 digits and found on Injector head.

N.B. – The coding information above is related to new diesel  Injectors. A remanufactured injector if purchased from an Authorized Field Repairer will also have a new calibration code, which is typically affixed to the injector as a sticker or label.


How can do Injector coding

The injector coding number should be noted by the technician prior to fitting the new injectors and after replacement is completed the technician can then program in the new injector numbers to replace the ones previously programmed into the ECU

Injector programming can be carried out with high level Diagnostic Scan Tools such as Autel Maxisys pro. Autel maxisys ms906bt

Care must be taken when reading the identification code stamped on the injector to ensure the correct number is entered into the ECU for the corresponding cylinder. Inputting an incorrect number or fitting the wrong injectors for the engine will result in the injector failing the programming procedure.

New Injector Calibration Data has been entered here. After pressing OK, the ECU will then check the number to complete the programming procedure

How to use PIWIS 2 tester Tampering with DME map data

Thursday, July 6, 2017 3:39:31 AM America/Los_Angeles

How to use PIWIS 2 tester Tampering with DME map data

tool and system : Porshce piwis 2 system

Information: Modifications to the hardware and software of the DME control module is not allowed.

Any alterations in the electronics or software (e.g. in order to improve the engine performance) may

have various effects, including a change in the permissible values for fuel consumption or exhaust and

noise emissions.

Starting with MY’02 911 Turbo (996) and MY’02 911 (996), you are able to perform a system test to

see whether the DME map data has been tampered with.

PST2 software version 12.0 and higher is able to perform this function.

Tampering with the DME map data will void the warranty.

Work Procedure: 1. Connect PST2 to the diagnostic socket; switch on the PST2.

2. When the PST2 is operational, select the Vehicle type from the Start menu.

3. Start the Automatic control unit search and wait until the search is completed.

4. In the function “Control units”, select DME.

5. In the menu “Function selection”, select “Control unit programming”.

6. Then select “System check”.

7. Then enter the old DME code. (The code obtained from IPAS)

8. The PST2 now states “Switch off ignition”.

9. The PST2 now states “Switch on ignition”.

10. After the system check, the following text appears in the info box in the PST2 display:

11. “Data record is OK” – indicates that there is no tampering.

12. “Data record was tampered with” – indicates that there is tampering.

13. Use the “ESC” button to return to the Start menu.

How to Reset the Tire Pressure Sensor

Wednesday, July 5, 2017 3:56:15 AM America/Los_Angeles

The National Highway Traffic Safety Administration (NHTSA) requires all models of cars and light trucks newer than 2008 to be equipped with a tire pressure sensor system. This law was enacted due to the high accident and mortality rate of cars and trucks with overinflated or underinflated tires being involved in tire blowouts or rollover accidents.

Direct or Indirect Monitoring System

There are two types of tire pressure monitoring systems (TPMS): direct and indirect. Each tire pressure system monitors the tire pressure within each of the tires and alerts the driver of low tire pressure (25 percent or more below or above recommended inflation pressure); however, the two systems monitor that pressure in two different ways.

The direct TPMS is used more often in the United States. The sensors are located in the tire pressure valve, which acts as an antenna, or are wrapped around the rim of the wheel with a band clamp. These devices transmit the information to an on-board computer. However, these devices can throw off the balance of a tire and can corrode in severe weather conditions.

The indirect TPMS is used more often in Europe. The sensors are located within the ABS braking system and/or the speed sensors of each wheel. They monitor the speed of the rotations of the wheels for any change since underinflated tires are smaller and rotate faster. Though they do not affect tire balance nor corrode, they must be reset with a scanning tool whenever tires are replaced or rotated.

Resetting Tire Pressure Sensor

  • Determine the type of TPMS system. If your car uses a direct system, resetting the tire pressure sensors may be as simple as pushing a reset button on the dash or following a menu as indicated in your owner's manual. If your car uses an indirect system, the system must be reset using a magnet or scanning tool by either a dealer or one you have bought yourself. Some systems have a reset button inside the glove box that needs to be pressed and held down for three seconds with the ignition on.
  • Inflate the tires. Make sure all tires are properly inflated. Remember you are setting the sensors back to "zero" so all tires must be properly inflated otherwise the sensors will not be calibrated properly and their readings will be incorrect.
  • Check the battery. If your car uses a battery to power the sensor, be sure that it is not dead. It is a good idea to replace the battery every five years. Sometimes this requires replacing the entire sensor unit since the battery is built-in.
  • Recalibrate the transponders. Each wheel has its own transponder. Rotating the wheels changes the location of each responder and the TPMS must learn their new locations. This relearning procedure differs from vehicle to vehicle but may be found in the TPMS chart in your manual or online. It is a good idea to change valve stems when getting new tires if the valve stems are also the tire pressure sensors.
  • Use the magnet method. With the key on but the engine off, press both the lock and unlock buttons on the key fob. After an initial chirp, place a magnet over each of the valve stems until the horn chips for each one in this order: left front, right front, right rear and left rear. Verify that the pressure readings are displayed on the driver information center.
  • Use the scan tool method. If no sensors are being replaced, you can follow the menu prompts for TPMS Reprogramming Procedure listed in the owner's manual.

Here we have instruction of how to use scan tool reset TPMS

what is BMW ECU / DME reprogramming re-flash and what can do it

Friday, June 16, 2017 11:33:14 PM America/Los_Angeles

There are many "myths" and misunderstandings about BMW ECU / DME reprogramming. We hope to help answer and give you solutions to the most commonly asked questions.

1 My mechanic/dealership says that you can’t reprogram, re-code, or swap a used BMW ECU between cars. How can you help me?


This is true, but we have the solution!

Ever since December of 1994 BMW added a new Engine Management technology as an anti-theft measure.

The new anti-theft technology is a device called the "EWS", which is also known as the "Immobilizer". This module compares the VIN number of the car between different electronic modules in the car. If the VIN number isn't consistent, the car will not start.

Also the EWS has a password feature called the "Rolling Code" which changes between the modules every time that the car is turned off. This makes it virtually impossible to swap used ECU's between BMW cars.

However, we’ve found a way to work around this.

We can reprogram a used ECU using another VIN number and reset the Rolling Code, virtually making the unit "virgin". Only then, can we successfully exchange and swap a used ECU to work in another BMW car.

2 Why can’t I buy a used BMW ECU online and install into my car myself?


Because if you install a used ECU in any BMW, the VIN number and Rolling Code will not match, and it will prevent the car from starting.

The EWS was created for this very purpose. What happens is that the EWS system connects with the key transponder, but fails to properly communicate with the DME. The car might crank, but the DME will never get the "permission" to power the fuel pump and send the spark signals.

.3 When I buy an Exchange BMW DME from you, will the unit be Plug and Play?

Our Exchange ECU's are programmed to your BMW's VIN number.

However, due to the fact that the EWS systems have a random "Rolling Code" we can't guess this code. Therefore, we reset this feature in order to make the ECU "blank".

In order for the unit to work in the car, a DME to EWS Alignment/Synchronization has to be carried out.

This is done using a BMW scanner like a GT1, ISTA, Autologic, Launch X431 or Baum Tool DS2021. It takes 5 minutes to "marry" the ECU to your car, and then the ECU is ready to start the car.

4 If you Repair my ECU, do you I need to “re-flash”, "re-code" or “re-program” the ECU before installing back into my car?


ECU re-programming is not required because most repairs are done on the hardware parts and not on the software programming. Therefore, the programming of the ECU will never be altered.

Every mechanic and dealership will often use different words and terms to explain to you how ECU's and scanners work, which can be confusing.

Here is a quick "definitions guide" to help you understand them better:

  • BMW Scanner: They are used to scan all the electronic modules in the car to find out what may be causing a Check Engine Light to come on, or to define fault codes found in the modules to figure out, and to install software updates on the electronic modules of the vehicle.
  • DME ECU Programming: This is the same as when you install the the Windows Operating System in your desktop computer. This process tells the DME to which car it will installed in and how it should manage the engine performance while the car is working. The reprogramming process takes an average of 45 minutes to 1 hour.
  • DME ECU Recoding: This process sets on the ECU the VIN number, programming codes, and transmission settings. Many times this process is done together with the ECU Programming.
  • DME Alignment/Synchronizing: This is a simple "Copy & Paste" process which takes only 5 minutes. The BMW Scanner copies the "Rolling Code" from the EWS and Pastes it in the DME memory. This process "marries" a new ECU to the vehicle allowing it to start.
