AUDI A6 Q5 ESL/ ELV Module J518 repair solution & repair kits

AUDI steer column Module – J518 is easy been damaged, it’s a common problem, when the J518

Module is failure, the following problems will occurred when insert the key:

1. Steer column will not be unlocked;

2. Car will not start;

3. Dashboard can not be light up.

But the key can rotate normally.

Repair solutions:

1. dismantle the J518 Module form the car, open it, use XPROG read the MCU, there are three kind of MCU Model exist:

 --- MC9S12DG256CFUE OL01Y;

 --- MC9S12DG128CFUE 1L59W;

 --- MC9S12DG128CFU 3L40K;

Read both the flash and eeprom dump from the MCU and saved on desktop, the XPROG wiring diagram:

2. Buy new MCU from www.u-obd.com, as the MCU is new and blank, use the XPROG write the dump been saved in the first step in to the new MCU, then solder back on the J518 circuit board.

3. Change the Relays Model No: ACT512;

4. Better change the micro switch and the ELV motor as well.

5. If the J518 circuit board is burned or badly damaged, or don’t want to do time -comsuming soldering work, better change a new blank circuit board.

Attention: When change the MCU, Desoldering the MCU, please mind the small resistors beside the MCU, The hot air gun may damaged the resistor, please be carful.

2. if the MCU is totally damaged and can not read the dump out, ask some one to share a dump, after write into the new MCU or new blank circuit board, use device to do adapting work.

Thanks for reading! If you like it please share to more people in need.

How to inspect the soldering work of a circuit board with microscope and amplifier

How to inspect the soldering work of a circuit board with microscope and amplifier

A good eyes is crucial for circuit board repairman, many times we didn't get our ECU, TCU, BSI, BCM circuit board repaired even we make great efforts, that because we didn't have good microscope to help us inspect if the PINs of a components are well soldered to the circuit board, here I recommend this mircroscope and amplifier with USB interface we can amplify any part of the electric circuit on the big PC screen

SUBARU Forester Smart key adapting method for all key lost tutorial

SUBARU Forester Smart key adapting method for all key lost

Preface:

We all knows SUBARU spare parts is very expensive, all key lost will cost a lot, here we share the SUBARU Forester key

adapting method for all key lost.

Abstract:

SUBARU Smart key all key lost key adaption have two common methods:

1. Disassemble the SMT Main ECU, Use AD900 programmer to write data into Toyota smart key, it can directly start the car, No need adapting on the car again, but must use AD smart key.

2. Disassemble the SMT Main ECU, immobilizer(ESL/ELV), Write initialization data, then study the key on the car.

Here we share the second method, SUBARU Forester use 5290 smart key, Year 2013, No immobilizer, disassemble the SMT Main ECU and ELV Write initialization data and study the key.

Process:

1.  Get the ELV(below steer column), disassemble the ELV module, find the 8 PIN EEPROMon the circuit board, Model No. : 93c46.

Desoldering the 93c46, use programmer and adapter read the data, make a backup first then change the code shown as below picture.

-keep the Red marked code code the same, others all change to F, When dump revised, use programmer and adapter write back to 93c46 eeprom, and solder back to the circuit board.

2. Disassemble the SMT Smart ECU(back side of the A column of the car), it’s appearance is the same as Toyota except the LOGO, disassemble the shell find the 8 PIN eeprom near the CPU, EEPROM Model No. : 93C86.  Disassemble the 93c86, Write initialization data, assemble back to the car, if without error the dashboard could be light up.

3. Use Key programmer add new keys directly.  Use K518, X300, or I80 key programmer, connect the car OBD interface, select SUBARU, then XV smart system, direct add new key, all down, after the keys added, no need sync, directly start the car.

Volkswagen 35xx instrument immo keyadapting tutorials all key lost

Volkswagen 35xx instruments cluster immo(New Jetta, New Santana, Skoda, volkswagen family the fourth generation immo manufactured after year 2013 ) all key lost adapting is an acknowledged head burn problems, many people try and then failed, here I got a new method to solve this tough problem, adapting new cars for volkswagen NEC 35xxinstrument cluster all key lost.

Abstract: because the volkswagen encrypt the 35xx instrument, result in the impossible to get the immo code from the eeprom without a key, when all key lost we can not adapting new key in term of the common methods. but we can get a alternative instrument cluster unencrypted sorts such as 24c32, 24c64(smart sort), via online adaption, let the volkswagen server write the original 35xx instrument cluster data into the alternative instrument cluster 24c32 or 24c64,  Ok, when this steps is down, we can use common methods to adapting 24c32 or 24c64 all key lost, because the alternative instrument cluster unencrypted, we can treat it as common all key lost case, when adapting work of 24c32 or 24c64 instrument cluster is down, we shifting back the 35xx instrument, all is down.

Devices & software needed: 35xx test cables, VCDS, VVDI2 Or K518, CN900, ODIS;

Process:

1. Use VCDS select the 25th column – immobilizer, advanced identification,  read the 35xxinstrument keys ID, record the ID (take picture or write down on a paper)

2. Change the instrument cluster 24c32 or 24c64, use the ODIS software online adapting.  Select 25th column – immobilizer, adapting immobilizer, stoped before adapting keys, ESC.

3. Common methods adapting new keys for 24c32 or 24c64 instruments all key lost, manually input the keys ID we record on the first step.  Use VVDI2 and 35xx testing cables to adapting 24c32 or 24c64 instrument keys on bench, there will be 6 steps, 1 to 5 steps, we follow it’s notification.

4. The sixth step: VVDI2 click read immobilizer data, then the interface will display VIN, CS code, PIN code etc, all the key position is FFFFFFFF, Blank. input the keys ID manually into the first and second key position. then click write immobilizer data, the two original car key ID already been write into the eeprom.

5. Click generate the distributor keys:  select the car brands and models, then select the OEM keys, select generate key1 or key2, then click generate distributor keys, down.

6. change back the original 35xx instrument cluster directly, the two keys no need study, cause their ID is the same as ID in the 35xx instrument,  no need study keys the car can start with the two keys.

Note: for fear the ABS code lost, better get the ECU and instrument adapting on bench, recommend buy the dedicated 35xx test cables, no need adapting on the car, decrease the risk of code lost.
