PSA AXN8 TCU IMMOBILIZER EMULATOR
![](https://www.ecuserwis.pl/wp-content/uploads/2024/07/AX8N_EMU.jpg)
A service to add an emulator to the PSA TCU AXN8 automatic transmission controller, where we read the PIN code and prepare the emulator to unlock the controller.
Once the emulator is connected in the car to the power supply and CAN bus, it unlocks the immobiliser implemented in the TCU AXN8.
The pin code is read out without opening the TCU control unit.
The service requires the TCU controller to be sent to my laboratory.
*If you have the PIN code of your TCU AXN8, we can prepare and send you a ready-made emulator.

Four wires should be connected: CAN-H, CAN-L, GND (ground) and +12 V IGN ( terminal „15”) or +12 V after the POWER relay.
Ensure the connection adheres to the vehicle’s repair schematics.
The colors of the corresponding wires are specified in the photo.
The location of the eeprom 24C02 memory is also specified in the photo.
Please remember the CAN terminator – terminator resistor J5 jumper, is in many cases indispensable especially when the TCU works standalone.
On emulator PCB we have 3 x LED GREEN, RED, YELLOW, thanks to them we can carry out diagnostics of the emulator connection, they clearly indicate the current status of the CAN bus connection and the status of matching to the TCU.
If you are an EU-based automotive electronics company, you can send us an TCU AXN8 unit for PIN code recovery and testing the emulator for service – please contact us or to one of My distributors .
In order to use this solution, the customer must be qualified as an automotive electronics technician and have the necessary diagnostic tools and wiring diagrams.
In the event of problems and the need for technical support, a CAN bus analyzer will be required in addition to the ECU files, as well as the ability to operate it.
