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.

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.
