Operation
Automobile audio will be locked up when power-off improperly. It only can work again after inputting the code.
To modify Kilometers. Change the Kilometer after odometer repairing or replacing.
To resume the original data. The device stores other data except kilometer and audio code, so you should write the original data into when the device data is lost or replacing with a new one.
Use as a programmer. Let you read/write, save, display, edit and copy the device data.
View and delete the saved data.
Audio Decoding
Audio mainly has two kinds: with IC, to decode by modifying the device memory; with address code, to decode by connecting diode or removing elements.
Audio with IC
1.
Operation
1-1 Please refer to《Diagrams and Charts Collection》for the audios supported.
1-2 Audio type with “-” behind, the code cannot be changed. Write the right file to get a fix code and the original one cannot be used.
Example: to write file “BMW-PH7850-1118” into the device, the code should be
"1118" behind “-”, if only “o” behind “-”, indicates the audio can run without any code.

Data Resuming
For resuming the original data.
⑴ Operation:
1. It has some original data except that the user saved. When data is lost or using a new chip, original data should be written into before adjusting. Or the odometer kilometer may display properly, but cluster running may be incorrect or car no start.
2. Volkswagen with Anti-theft II or III system, such as Passat B5, Audi A6, Bora and Polo, its kilometer and anti-theft code are stored in a same chip. Resuming the data will make the anti-theft code changed, so after resuming is completed, need to process by trouble coder decoder to start the car.
All the data may be covered when doing this operation and cannot be resumed.
Important data must be saved first!!!
⑵ Example:
Now we have a VW A6-1.8 with barcode 4C0920900 needs to resume the data because of lost data due to a damaged chip. Note: bar code commonly on the cluster.
1. Look up《Diagrams and Charts Collection》and find “4C0920900” under “VW” in
《Data Resuming·Original Data》 to confirm this instrument has original data for this type.
2. Put a new chip (the original one damaged, the chip used: 93C86) onto the adapter and note its direction.
3. Insert the adapter into the instrument.
4. Start the instrument and select “Resume Data” and press “OK”.
5. Select “VW” and press “OK”.
6. Select “4C0920900” and press “OK”.
7. It prompts you “Well Connect the Device!” and the chip used displays. Press “OK”.
8. Then it prompts you “Save the Device Data?” Press “ESC” because it’s a new device.
·11·
www.autoecu.com.cn 科技创新 超值服务
9. The instrument writes the data into this device. When it prompts you “Data Written into
Success!” press “ESC” three times to exit.
10. You need to adjust the odometer to a wanted kilometer after original data written into. Refer to “Cluster Adjusting”. That’s to select “Adjust Cluster”→“Audi”→
“A6”→“VDO 99-01 C86”→“Adjust Km”→Input a Km→“OK”.
11. Mount the cluster back to car. As this car with Anti-theft II system, the kilometer and anti-theft code are in one chip, anti-theft code will be changed when rewriting original data. So need to process by trouble code decoder after adjusting.
Note: Those clusters with no anti-theft can work normally again after back to car.
12. To process with a trouble code decoder, you need to input an anti-theft code; please contact the manufacturer to get this code.

Appendix
Ⅰ.Attentions when adjusting
1. Must save data first before adjusting.
2. A cluster commonly has one chip, usually 8-pin IC. Please note its direction when removing it from board.
3. Device can be rewritten times. The same type device may use in different cars, but the data may be different. E.g. Citroen 988 and Hongqi Century Star use the same kind device X5045, but memory in each is totally different.
4. If you want to verify the cluster working properly, electrify it as picture shown in《Diagrams and Charts Collection》. Usually the power supply should be +12V, but HONGQI +5V.
5. For some clusters, you need to pull out the cluster hand to remove the chip.
5.1 Do not pull those with hairspring (that is the hand may return automatically when power off). For those hands don’t return when power off and return to “0” when power on, it can be pull out, such as Passat B5, A6, Bora and Polo, if no especial instruction.
5.2 For BMW 530 and some other BMW clusters with hairspring, clamp the rotor to make it not move then pull the hand out. Or the cluster may be damaged.
5.3 Buick Sail hand is easy to damage when pulling.
5.4 For Honda 2.0, 2.4, do not pull the hand; you can make a hole on the plastic.
5.5 For Jetta, do not remove the motor, or it may make the hand wiggle. Just pull the hand it may be OK.
6. VW with anti-theft system:
6.1 With anti-theft II: Passat B5 (1.8/1.8T), Audi A6 (1.8/1.8T), Bora and Polo.
6.2 With anti-theft III: Passat B5 (2.0/2.8), Audi A6 (2.4/2.8)
6.3 Switch off the ignition before removing the cluster. Do not start the car after removing it from car, or the anti-theft may start.
6.4 Select the right type and use the original chip to adjust, the anti-theft will not start.
6.5 When using a new chip or data was lost, resume the original data first.
6.5.1 Resume original data you saved and then to adjust, the anti-theft may not start.
6.5.2 Resume the original data in the instrument and then to adjust. When putting it back car, the anti-theft starts, need a trouble code decoder.
7. For some cars, the kilometer/Mile stores in two places, such as Peugeot, Picasso, New Benz,
New BMW. Do not try to modify yourself if not supported.
Example: You have a Picasso cluster to be adjusted and you have saved data and then to modify it. It may display 990,000Km after back to car due to incorrect modifying and now another place will memorize this Km, it may be 990,000Km even if you resume the data.
8. For BMW with 35080, replace it with a new one if you want a lower Km.

Ⅳ. How to Remove and Weld Devices
Ⅰ.Welding preparation
1.Soldering Iron selection
Soldering iron must be connected to a reliable GND, If have no constant temperature soldering iron, then select the soldering iron of 20W (heater inside) or iron of 25W (heater outside); The inside one should be less than 25W, the outside should be less than 30W.
2.Welding-aid selection
Use rosin as welding-aid substance, never use strong corrosive soldering tin paste, if rosin has been carbonized & becomes black, replace it.
3.Soldering wire selection
Select rosin activated core wire with low melting point.
Ⅱ.Chip Removing
1. When removing DIP device, use a suction gun or suction pipe to clean welded tin. Do not pull it by force.
2.When removing SMD device, smelt more rosin to the pins and use soldering iron to heat the pins until the device gets entire loose, and then remove it. Do not pull it by force.
3.Heating time should not be too long to avoid any damage to the chip.
4.The chip on board is commonly protected by protecting lacquer, use soldering iron to heat protecting lacquer at first (heat to 70-80℃), then remove the chip after the protecting lacquer is cleaned.
Ⅲ.Chip welding
1.Welding time should not be too long to avoid any damage to the chip
2.Soldering iron is easy to be oxidized in high temp for a long time, clean the head of the soldering iron often to keep it clean.
3.Heat transferred by soldering tin when welding, put soldering iron head on chip will do no good to welding.
4.The chip shall not be moved or quivered before welding concreting.
5.When welding SMD, weld two diagonally pins to fix chip first, then weld others.
