If the vehicle is turned off, it may refuse to enter "READY" mode again. The high-voltage contactors will stay open to isolate the pack.
The car may refuse to accept a charge from either level 1, 2, or fast chargers. Top Causes of P3180-97 in Nissan Vehicles
When you encounter the part number , you are looking at a genuine replacement bolt for a variety of Nissan models, including the Armada, NV vans, and others. It is not a diagnostic trouble code, but a critical, safety-related fastener.
The P3180-97 code rarely appears out of thin air. In the vast majority of cases reported by Nissan owners on communities like Drive2 and [MyNissanLeaf](https://mynissanleaf.com/threads/my-first-leaf-my-first-problem-p3180 and-p33d4-2-days-after-buying-it.38958/), it is triggered by one of the following root problems: 1. Severe Cell Imbalance or "Crashing" Cells
A paradox frequently encountered in imported Nissan Note e-Power vehicles is that a completely dry fuel tank will trigger high-voltage battery faults. Since the gas engine acts strictly as a generator to feed the small traction battery, a lack of fuel causes the engine to stall or fail to initiate. The vehicle will attempt to compensate using the remaining small battery charge, completely draining it past its threshold, forcing the EVCU to lock out the system with error P3180-97. 3. Low Voltage or Failing 12V Battery
Because this involves high-voltage systems, diagnostics should be performed with caution, often requiring specialized tools like an insulation tester.
and hybrid vehicles, such as the Nissan Note e-Power and Nissan Serena. This error typically signals a severe state of the high-voltage (HV) battery, often colloquially referred to by enthusiasts as "bricking" the battery management system (BMS). Understanding Error Code P3180-97
: The car drastically limits acceleration and speed (often capping it to around 25 mph) to prevent thermal or electrical catastrophes.
The boot corresponding to part number is subjected to a brutal environment. Located behind the wheel, it endures:
Faulty radiator fans or AC compressors can sometimes cause electrical feedback that triggers battery system errors.
Primarily affecting Nissan’s electrified vehicle lineup—including the Nissan Leaf EV and e-Power hybrid models (like the Note and Serena)—this specific trouble code indicates that the vehicle's Electric Vehicle Control (EVC) unit has registered a profound malfunction or total data loss from the battery's internal management computer. In the automotive technician community, triggering this code alongside its sister code C1B5B is frequently referred to as "bricking" the battery management block. What Does the "-97" Sub-Code Mean?
