NISSAN CONNECT 4 – AIVIL42P0: CAN Filter Installation Guide
The Nissan Connect 4 navigation unit (AIVIL42P0) becomes immobilized when removed from its original vehicle, preventing its use in another car or for extended bench testing. Typically, the first time after removal, the unit remains operational on the bench for approximately 30 minutes before displaying the message:
“SYSTEM IS LOCKED. RED, PLEASE CONTACT YOUR NISSAN DEALER.”
Once this message appears, the unit is locked and cannot be used or tested further. Unfortunately, Nissan dealers are generally unable to assist with unlocking previously used units.
AIVIL42P0 unit used in:
- Nissan Juke F16 2018-2025
- Nissan Altima L34 2018-2025
- Nissan Micra 2018-2025
- Nissan Rouge T33 2020-2025*
- Nissan Z RZ34 2022-2025*
*Note: Units used in non-EU markets typically do not have the immobilizer function activated.

Connectors quantity and type on the back panel might be different and depends on model hardware configuration.
Testing on the bench
Examining the system wiring in the car, you can notice that ACC and Ignition wires are not available in the wiring anymore, only constant power is supplied to the system. The system wakeup is now carried out over the CAN bus. However, examining system hardware reveals that ACC and Ignition signals over separate wires are still supported internally. This discovery allows the system to be powered on the bench by applying these signals to the corresponding pins.
External CAN bus filter installation
To test the system on the bench while overriding its security—or to permanently install the radio in a different car—a CAN filter (emulator) can be installed on the external wiring.
Important! The CAN bus filter must be configured for this unit type by soldering jumper J1 on the PCB.
Connection & Configuration
- Power Supply:
- Connect the CAN filter’s +12V and GND pins to constant power.
- CAN Connection:
- Connect the CAN filter CAN2 lines to the unit’s V_CAN lines.
Testing Scenario:
- For bench testing, only the CAN bus connection between CAN2 (emulator side) and V_CAN (unit side) is required.
- CAN1 connections can remain unconnected during bench tests.
Vehicle Installation Scenario:
- For in-vehicle installation, the CAN1 connections must also be connected.
- This involves cutting the V_CAN wires in the car’s wiring harness and connecting the CAN filter in series with the unit.
Internal CAN bus filter installation
The CAN filter can be installed inside the navigation unit, providing a more integrated solution that allows the unit to be used seamlessly in any compatible vehicle.
Key Considerations:
- This installation requires advanced electronics knowledge and soldering skills.
- It is recommended for professionals only due to the complexity and risk of damaging internal components.
By performing an internal installation, there is no need for external wiring modifications, offering a clean, OEM-like appearance and permanent security override functionality.

Hello! Can i find a diagram of connectors near antennas of aivil40? I want to install it in a 2017 xtrail and before starting to build an adapter frame, i need to know i have all connectors ready. Thank you!
Hi. I do not have a full wiring diagram for this model.
Buongiorno sto installando l’emulatore per un Nissan AIVIP32R0,seguendo le connessioni relative al NISSAN CONNECT 4,ma non riesco ad uscire dal blocco.
Il led arancione dell’emulatore è sempre lampeggiante, può aiutarmi? Devo variare qualcosa nei collegamenti? Attendo notizie.
Angelo Manuguerra
Ciao,
Hai dei ponticelli saldati sull’emulatore? Questo tipo di unità non richiede ponticelli saldati e dovrebbe funzionare immediatamente. Verifica di aver effettuato correttamente i collegamenti del bus CAN.
Buongiorno, grazie della risposta, effettivamente levando il ponticello sull’emulatore l’unità si è accesa ed è funzionante. Poichè devo installare l’emulatore all’interno dell’unità e non ho la macchina del cliente a disposizione, staccando il pin 44 dalla massa l’unità non si riaccende sul banco: devo collegarlo internamente a massa per farlo funzionare in macchina?

I have fitted this emulator into an F16 however I still have the locked RED message.
I have:
Removed the two can resistors inside the board
Soldered J1 jumper (also tried with jumper disconnected)
Tried the +5v line as shown in the picture, but I have also tried +12v directly from the connector
I see a steady flashing orange light from the emulator. Any help would be so highly appreciated
Please write me model/part number of the navigation unit on your F16 Juke. Is it AIVIL42P0 or different ?
If its a AIVIL42P0, you have to wait learning process to complete as shown in video. For this type unit J1 must be shorted
Hi
Fitted to a 21 Juke, radio sat nav etc all work which is great but reversing camera can not be accessed by manual button or by selecting reverse. Scan with Thinkcar shows audio not installed. Any ideas?
Hi, radio should be configured with correct reverse camera option. It can done using nissan consult diag tool.
Hi, do you know if the emulator works with YBN-AIVIV20 for Renault, the connectors look the same as for Nissan so maybe it will work?
Hi, i have not tested it on AIVIV20 for Renault yet. It must be tested.
hi can you unlock the nissan juke 2020 head unit thank you
Hi, What you mean unlock Nissan Juke head unit? If you want to use a 2nd hand unit, and have a message “System is Locked”, it is possible to solve this problem with CAN filter (security emulator). CAN filter can be installed on the radio wiring or inside the radio.
