1. Caution on testing VW Airbag2000-2001 Golf/GTI/Jetta/Beetle Airbag System (important!)

Air Bag Warning Lights stay on permanently after testing with X-431. The Air Bag Controller shows DTC number 65535, indicating an internal error

which cannot be cleared. This problem seems to be limited to airbag controllers with the part number 6Q0-909-605-A. If you have a 2000-2001 Golf/GTI/

Jetta/Beetle, or similar SEAT or Skoda model, you should physically inspect the airbag controller and look at the part number. If it is not 6Q0-909-605-A,

then it should be safe to scan. if it is 6Q0-909-605-A, then it is at risk of this problem -- please avoid scanning the airbag controller in these cars, unless

you are prepared to but a new one!

If you unintentionally connect to the Airbag controller with the part number 6Q0-909-605-A, please immeadiately click [exit] to quit. If you insist on

doing the following tests, the company will disclaim the responibility for all the results produced. Accessing the other control modules in the car should

not affect the airbag controller in any way.

Comment: There is no way that testing a controller should cause it to become dysfunctional in this manner. We believe there is a bug in the firmware in

these controllers. We also believe VW knows this, but isn't admitting it. The affected controllers are no longer available as replacement parts, they have

been superceeded by a new part number - 1C0-909-605-A which appears not to have this problem.

How to Match Mercedes-Benz W220 Instrument (ICM)

All kinds of monitor gauges, such as tachometer, oil pressure, water pressure, fuel storage, light, working status and travel meter locate on Instrument

Cluster. And we can promptly obtain the correlation information from the display board.

When the automobile locates a different region, we can set the distance unit, temperature unit and country language that displays on the instrument cluster.

When the automobile achieved maintenance time / distance interval, it needs reset oil service indicator. Here, how to use the Launch X-431 for matching

Benz W220 instrument cluster is discussed.

After entering instrument system (ICM), the screen will display as Fig 1. Select control unit adaptations to enter the menu as shown in Fig 2. Here we can

set / reset the options: distance unit, temperature unit, language and oil service.


45/68

1. Distance unit

We can set the distance unit (kilometer and mile) displayed on the instrument if necessary.


46/68

When setting distance unit, select the first menu on Fig 2. Firstly, X-431 will read the current distance unit (Km or Miles), and then the user can press the

button to choose the unit (e.g. F1 for Km and F2 for Miles). See Fig 3. After confirming the distance unit, the screen will display the interface as shown in

Fig 4. Press YES in Fig 4. then the unit will display as shown in Fig 5.


47/68

2. Temperature Unit

We can set the temperature unit (C & F) if necessary under this option. See Fig 6. Firstly, X-431 will read the current temperature unit (C & F), and

then the user can press the button to choose the unit (e.g. F1 for C and F2 for F) See Fig 6. After confirming the temperature unit, the screen will displaythe interface as shown in Fig 7. Press YES in Fig 7. then the unit will display as shown in Fig 8.


48/68


49/68


50/68

4. Oil Service

When a reset symbol occurs on the instrument cluster, it needs to reset the oil service indicator. It has 3 options: 229.1, 229.3 and 229.5. See Fig. 12. Users

can choose the different option as the different model and different oil specification. After press OK, X-431 will prompt that 'Has an oil change been

carried out?' See Fig. 13. After confirmation, X-431 will reset oil service indicator of itself and the reset symbol on instrument will disappear. It will

display new travel course.


51/68

Generally, modern car's instrument divides into two parts: one part is the panel before steering wheel and instrument covers and platform; another is vice

panel on the driver's side channel. We can know the working status of the car and make some corresponding adjustment according to the various

information displayed on instrument.

Toyota Diesel Injector Reprogramming

To balance Injection quantity deviation among injectors, Toyota developed a software compensation method for the new common rail system, which

compensates injection quantity deviations among the injectors. Speciffically, by adopting a two-dimentional code, each injector has a 30 digit code that

contains its own deviation. The engine ECU then reads deviations of the injectors during assembly and compensates for them. As a result, the system can

keep performing injections with required small fuel quantities, at high accuracy during its operation.

The following will introduce the process to reprogram Diesel injectors with X-431:

Condition: Toyota Software version must be V31.03 or above. CAN BUS II connector is selected in this operation.

After download Toyota Software and enter Engine system, clickWORK SUPPORT in the function menu interface, see Fig. 1. below. Then X-431 will

search all available special functions for this system and display it as in Fig. 2. below.


52/68

ClickInjector Compensation to enter next menu, see Fig. 3.

1. Set Compensation Code: is defined to write new injector code into ECU.2. Read Compensation Code: is used to read each injector code information from ECU memory.

You must select an injector that you want to perform this function after you click any above item displayed in the Fig. 3. interface, see as Fig. 4.


53/68

Read Compensation Code function is very useful when you forget the injectors corresponding position after they are all removed out and disarranged.

You can also save the code after you perform this function.

Set Compensation Code contains 2 items: Fetch a code from the preserving and Handwork input code, see Fig. 5. The previous function is used to

fetch the saved code if you have performed Read Compensation code, it is convenient to match any injector that its code can be fetched from preserving

if you only change injectors position with each other without replacing any one.

The latter Handwork input code is used when new injector(s) is installed, because the new injector code is not memorised in the ECU, so you have to

input it by hand to match. The input code interface is shown as Fig. 6.

After finished Match working, you can perform Read Compensation Code again to check the code is coherent or not. If it is coherent, well done! The

injector reprogramming has been successful.

BMW Air-mass Flow Sensor Reset For Diesel Engine

In normal operation, the air mass flow meter is subject to effects such as soiling and ageing. Those effects cause divergence between the stored

characteristic and the specified status resulting in symptoms such as lack of power or black smoke. In order to prevent the effects of this problem, the Air

mass flow meter adaptation function has been introduced on the DDE5.

Function:

Air mass flow meter adaptation is performed by the DDE control unit at two operating points: when idling and under load in an operating range defined as

follows:

- Engine speed = 1700 ... 3000 rpm

- Charge-air pressure = 1100 ... 2800 mbar

- Speed = 90 ... 160 km/h

- Change in intake air temperature < 2/s

- Change in injection rate < 2mg/stroke/s

- Delay period = 3s

Adaptation sequence at each of those points:

The air mass flow meter adaptation uses certain operational data to calculate the theoretical air mass flow passing through the engine. The DDE control

unit compares the figure obtained with the level measured by the air mass flow meter.

If the DDE control unit finds that the measured level differs by more than 8% from the theoretical figure, that difference is stored on the control unit as a

compensation factor.

That compensation factor enables the control unit to adjust the measured levels before they are processed by the various functions.

Application:The service function Air mass flow meter adaptation must be performed after the air mass flow meter is replaced. The stored compensation factors are

reset to 0 in the process.

Vehicle use:

The air mass flow meter adaptation is used as follows:


59/68

The air mass flow meter adaptation is used as follows:

- E46 M47TU: as of volume production launch


- E65 M57TU: as of 03/2003 with integration stage 6.108 and DDE software VQ5.7
