P1615 INFINITI: KEY DIFFERENCE
P1615 NISSAN: NVIS DIFFERENCE OF KEY
Over the years, vehicle manufacturers have designed various systems to ensure safety levels. One of these is the immobilizer, a component whose function is to avoid or prevent the engine from operating without the presence of the correct key. With this system, a considerable reduction in car robberies is achieved taking into account that, thanks to this system, the car is prevented from being hot-wired.
The most recent immobilizer systems have advanced cryptographic codes or IDs. It is through these that it is able to avoid the key or controller code from being replicated. Inside the key, there is a microcircuit that is activated by an electromagnetic field that is responsible for inducing the electrical signal in the key body, which produces the binary code that is scanned by the ECM (Engine Control Module) or a corresponding module.
When the P1615 OBDII fault code is set it is because the IMMU or Body Control Module received the key ID signal, but the result in the ID check does not match the one stored in the IMMU.
The P1615 OBD2 diagnostic code is set for one of the following reasons:
The steps to follow to correct the DTC P1615 OBDII code are:
