Nissan P318097 -

: 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

The code (often colloquially referred to as "Nissan P318097") is a critical diagnostic trouble code (DTC) primarily associated with the high-voltage (HV) battery systems in Nissan e-POWER and Nissan Leaf electric/hybrid vehicles. Understanding Diagnostic Code P3180-97

While the code points to the battery system, the root cause may be an external component leaking current to the high-voltage lines: 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.

: Tools like LeafSpy are used to check the voltage of individual cells to identify "crashing" modules. : In Nissan’s diagnostic language, the sub-code "97"

: Dirt or moisture in HV connectors (such as the charging port or inverter plugs) can cause insulation resistance to drop below the safety threshold. Diagnostic and Repair Procedures

: Common symptoms include a "No Start" or "No Ready" condition, the car entering a "Reduced Power" or "Limp" mode, and multiple dash warnings related to the EV/HV system. Because the compressor is powered by the high-voltage

Diagnosing P3180-97 requires specialized tools due to the high-voltage risks involved.

: 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 older Nissan Leaf models, a "dead cell" or a significant voltage drop in specific battery modules can trigger P3180, leading to a loss of power.
