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 AXN8 module to be sent to my lab, or full bin files from the AXN8 module to be uploaded.

*If you have the PIN code of your TCU AXN8, we can prepare and send you a ready-made emulator.

*If you have the files from the AXN8 TCU, we can calculate the PIN and prepare a ready-to-use emulator, there is then no need to send the AXN8 TCU module to us.

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.
