Faulty A/C compressors, radiator fans, or coolant pumps have also been reported to cause feedback that trips these codes. Next Steps Fault code P3180 causing reduced power mode in Nissan Leaf

Nissan P318097 is a complex error code that requires a thorough understanding of the vehicle's fuel system. By understanding the causes, symptoms, and solutions to this code, vehicle owners can take the necessary steps to diagnose and repair the issue. Regular maintenance, such as checking the fuel filter and fuel pressure sensor, can help prevent the P318097 code from being triggered. If you are experiencing issues with your Nissan vehicle, it is essential to consult a professional mechanic who can diagnose and repair the issue efficiently.

This sub-code typically indicates a specific component or system behavior within the larger fault category, often pointing to an "isolation" issue—meaning the high-voltage system has come into contact with the chassis ground, which is a safety critical failure.

Repairing the battery pack by replacing the specific "dud" or dead cells, which requires specialized handling.

| Format | Example | Meaning | |--------|---------|---------| | 5-character DTC | P0300–P3499 | Standard OBD-II code | | 10–12 digit numeric | 318097-XXXX | Part drawing or assembly number (often found on castings) | | Alphanumeric with "P" prefix | | Likely Parameter/Calibration ID for an ECU or TCU | | "P" + 7 digits (no letters) | P318097 | Uncommon for parts; common for calibration files |

For definitive verification, connect a or a high-end Autel/Launch X431 scanner, go to "ECU Identification" or "Calibration Info", and check if P318097 appears as a field labeled "Calibration Number" or "Program ID". If so, it’s simply a version label—not a fault. Faulty A/C compressors, radiator fans, or coolant pumps

The computer networks (CAN bus) responsible for monitoring the high-voltage system are completely powered by the standard 12-volt auxiliary battery. If this 12V battery drops close to or below 12.0 volts, the computers will log erratic sensor readings, drop communication packets, and misinterpret normal battery states, triggering false-positive system failures. 4.

: A manufacturer-specific code indicating that the Vehicle Control Module (VCM) has detected an error signal originating from the Lithium-ion Battery Controller (LBC) or Battery Management System (BMS) for longer than 0.02 seconds. Regular maintenance, such as checking the fuel filter

Nissan's official service manual provides a specific diagnostic procedure. The manual's first instruction for P3180 is to: "Check the DTC which detected with Li-ion battery controller" . This confirms that P3180 is a secondary code; the primary fault lies within the battery's controller.

This is a very common cause. One or more cells in the battery pack may have degraded faster than others, leading to a massive drop in voltage ("cell crash") and triggering the P3180 code.
