This specific error is typically categorized as a . When a vehicle triggers this code, the Hybrid Control Module (VCM) detects that high voltage is potentially in contact with the chassis ground, which is a major safety risk.
While the code points to the battery system, the root cause may be an external component leaking current to the high-voltage lines:
: Tools like LeafSpy are used to check the voltage of individual cells to identify "crashing" modules.
: 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.
: 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
: 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.
