Nissan P318097 ((install)) (PLUS — 2024)

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

: 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.

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

: 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. While the code points to the battery system,

: 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

: Technicians use an insulation tester (megohmmeter) to inject high voltage into the battery and check for leaks to the chassis. : In Nissan’s diagnostic language, the sub-code "97"

: Ironically, a weak or discharged standard 12V auxiliary battery can cause "ghost" codes in the HV system. Technicians often recommend testing and charging the 12V battery first.

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
