What Does Code P1612 Mean? DTC P1612 is a manufacturer-specific diagnostic trouble code typically indicating an issue within the vehicle’s immobilizer system, often associated with Subaru vehicles. The code, often referred to as an “SBDS Interactive Code,” signifies a communication fault or an integrity failure within the security link between the Engine Control Module (ECM) […]

What Does Code P1613 Mean? DTC P1613 is a manufacturer-specific diagnostic trouble code, primarily indicating an issue within the vehicle’s immobilizer or anti-theft system’s communication with the Engine Control Module (ECM) or Powertrain Control Module (PCM). The brief description “SBDS Interactive Codes” points to a communication fault within a proprietary diagnostic system, such as Subaru’s […]

What Does Code P1614 Mean? DTC P1614 typically indicates an issue within a manufacturer-specific interactive system, often related to the vehicle’s security or immobilizer system, such as Nissan’s NATS (Nissan Anti-Theft System). The Engine Control Module (ECM) or Powertrain Control Module (PCM) detects an invalid, missing, or improperly synchronized signal from a networked control module […]

What Does Code P1615 Mean? The OBD-II diagnostic trouble code P1615 indicates a malfunction within the vehicle’s immobilizer system, specifically an issue with the communication between the Engine Control Module (ECM) or Powertrain Control Module (PCM) and the NATS (Nissan Anti-Theft System) or a similar manufacturer-specific immobilizer control unit. This code signifies that the ECM/PCM […]

What Does Code P1616 Mean? DTC P1616 is a manufacturer-specific diagnostic trouble code, most commonly associated with Nissan and Infiniti vehicles. It stands for NATS (Nissan Anti-Theft System) Control Unit – Malfunction or ECM-NATS Communication Error. This code indicates that the Engine Control Module (ECM), also referred to as the Powertrain Control Module (PCM), has […]

What Does Code P1617 Mean? DTC P1617 indicates a fault within the vehicle’s immobilizer system, specifically related to an “Interactive Code” condition, often associated with manufacturer-specific anti-theft systems like Nissan’s NATS (Nissan Anti-Theft System). This code signifies that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an irregular or absent communication […]

What Does Code P1618 Mean? DTC P1618, often identified as “SBDS Interactive Codes” or “Brake System Malfunction – VDC Control Module,” is a manufacturer-specific diagnostic trouble code primarily associated with Subaru vehicles. This code indicates a communication failure or an internal fault within the Vehicle Dynamics Control (VDC) system that prevents the Engine Control Module […]

What Does Code P1619 Mean? DTC P1619 indicates a malfunction within the vehicle’s immobilizer system, specifically an issue with the “SBDS Interactive Codes” which typically refers to a failure in the communication or authentication process between the Engine Control Module (ECM) / Powertrain Control Module (PCM) and the Immobilizer Control Unit (ICU), often designated as […]

What Does Code P1620 Mean? Diagnostic Trouble Code P1620 typically indicates an issue within the Theft Deterrent System (TDS) fuel enable circuit, signifying that the Powertrain Control Module (PCM) or Engine Control Module (ECM) is not receiving a valid fuel enable signal from the anti-theft module. This signal, often referred to as the PassLock, VATS […]

What Does Code P1621 Mean? DTC P1621, often interpreted as “Control Module Long Term Memory Performance / Immobilizer Code Words Do Not Match,” indicates a critical issue within the vehicle’s Engine Control Module (ECM) or Powertrain Control Module (PCM) related to its non-volatile memory (NVM) and/or the vehicle’s immobilizer system. This code fundamentally points to […]
