How to Read ECM Anti-Theft Passwords with LAUNCH X431 IMMO PLUS
When the BSI cannot read anti-theft passwords, then you can use the LAUNCH X431 programmer to read anti-theft passwords from engines in the BENCH mode. This article shows how to do this using a Peugeot/Citroen vehicle as an example.
Function Introduction:
Anti-theft Password Reading — All Lost Anti-theft Password Reading — ECM.
Requirements:
Device required: LAUNCH X431 IMMO PLUS/ X431 IMMO Elite.
Software required: Peugeot, Citroen V10.20 and later.
Procedure:
It is roughly divided into three steps:
a). Open the programmer software to obtain the wiring diagram, and connect the engine computer in the BENCH mode.
b). Use the IMMO programming software to read out the EEPROM data of the engine computer and save it as a backup.
c). Enter the Peugeot/Citroen IMMO software, and decrypt the anti-theft password by loading the EEPROM data.
The following details the operation steps and related precautions for reading the engine password.
1. Enter the [IMMO PROG] software. Connect the device and programmer hardware as shown in the figure, and then click OK.
2. Choose the [Engine] module and choose the corresponding menu according to the engine manufacturer and type. Take MED17.4 as an example here: choose the [MED17/ EDC17/ ME17 Series] menu.
3. Choose [Search For ECU Model]. Enter the ECU type name of the engine, as shown in the figure, enter MED17.4, and click OK. Then, the type will be recognized automatically
4. The type TC1766 is recognized. Click OK.
5. Precautions are shown in the figure below. Click OK.
6. Choose [View Wiring Diagram] to obtain the wiring diagram.
7. Connect the ECU according to the wiring diagram.
8. After connecting the ECU, choose [Backup EERPOM Data] to execute the function and start to read and save EEPROM data.
Wait for the completion of EEPROM data reading. After EEPROM data reading is completed, enter the file name to be saved.
9. Choose and confirm the save path of the file. File backup is successful.
10. Click the Peugeot and Citroen logo to enter the software as shown in the figure below, and choose [Anti shift Password Reading] — [All Lost Anti-theft Password Reading] — [ECM]. Choose the ECM type to be read, and take MED17.4 as an example to demonstrate.
11. After you choose the type, the following prompt box will pop up. We have already backed up the EEPROM data in the previous steps, so we can click OK to continue.
12. To perform this function, you need to connect to the network to ensure that the device network
is smooth. After confirming the network connection, we continue, choose the saved EEPROM data and click OK. Here choose MED17.4.
13. Wait for the password to be read, and then a success message will pop up.
