Nissan: P318097

: One of the most documented causes for P3180-97 in Nissan Note e-POWER models is a failing air conditioning compressor. Because the compressor is powered by the high-voltage battery, an internal short can leak current, triggering isolation faults like P3180-97 and P0AA6.

The vehicle will not start (Ready light does not come on), and you may see a "Hybrid System Error" on the dashboard.

: If the internal computer has locked out due to deep discharge or a software glitch, specialized EV repair shops must remove the battery controller, read the EEPROM memory chip, and rewrite it with a clean, uncorrupted software "dump" from a functional donor vehicle.

: Identifies a generic, manufacturer-controlled fault in the High Voltage Battery System. nissan p318097

: Because e-POWER engines only serve as generators, running out of gas forces the car to rely entirely on the HV battery until it is dangerously depleted. Extreme Cold

: If a specific part—like the A/C compressor—is found to be leaking current, it must be replaced to restore the system's insulation integrity. Maintenance & Parts nissan note epower repair part 1

: In Nissan’s diagnostic language, the sub-code "97" often refers to a system component failure where the signal is not reaching the control module or is invalid. Common Causes for P3180-97 : One of the most documented causes for

: Low coolant levels in the inverter reservoir can cause overheating, leading to power reduction and system errors. Recommended Steps

In the context of genuine factory parts, . It's important to note that, like many factory-engineered fasteners, this part is often designated as a "VIN-specific" item, meaning its exact fit can depend on your vehicle's unique chassis number.

: Standard OBD-II scanners often cannot clear this code because it is stored as a "permanent" or "critical" fault in the BMS. Common Causes : If the internal computer has locked out

To understand the P318097 link, one must understand the engine it inhabits. Introduced in the 2018 Infiniti QX50 and later utilized in the Nissan Altima, the VC-Turbo engine solves the age-old engineering trade-off between power and efficiency.

If the gasoline engine (generator) fails to start—due to lack of fuel or mechanical failure—the HV battery can drain below its critical threshold. A/C Compressor Short:
