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.

Fault code & symptoms: The car can not start after the replacement of the instrument cluster, the diagnostic devices detect the immobilizer triggered, the fuel signal stopped.
Devices needed: OBDSTAR X100 PROS

1. Use the X100 PROS read the immobilizer code, select GM - read immobilizer code.
     Save the code(will be used when adapting)

2. Use the X100 PROS select GM adapting, input the immobilizer code wait another 12 minutes, then follow the X100 PROS notifications step by step.

A Bosch M7 ECU common failure repair experience

      The Bosch M7 ECU has a common failure, the water temperature sensor ground connection is prone to burn off the circuit, the failure is result from two main reasons: 1. the water temperature sensor is damaged; 2. the water temperature sensor electric circuit short circuited. Repair the water temperature sensor electric circuit, then open the M7 ECU, There are two PINs for ground connection, use a electric wire connect the ground pin to centre to solve this problems
