How to access the self-diagnosis menu of the Nissan Primera MK3

Model: Nissan Primera MK 3 - Years 2002-2008
Part: Instrument cluster

On the Nissan Primera, there is the possibility to access a secret menu that allows for a sort of self-diagnosis: in this video we can briefly see how it is done. On the central dashboard, we press and hold the "info" button, then turn the volume button. In this way, two options will appear on the display, including "self-diagnosis" which is already highlighted. We confirm the choice by pressing the central button, and in this way we can see the progression of the diagnosis as it is done by the system: we just have to cross our fingers and hope that no errors are found, which in case they are reported at the end of the scan.

If the central locking system of the Volkswagen Golf 4 is not working, it is likely necessary to reset the system: to do this, open the driver's door and detach the side panel of the dashboard next to the steering wheel. Under this panel, you will find the fuses, including the one for the central locking, which is indicated in the manual as number 14. To reset the system, remove this fuse from its housing, then reinsert it or replace it with a new one of the same amperage: this will reset the central locking system.
