Nissan - P318097
Who is this for?
Final Score: 9/10 (For Motorsports Use) The P3180-97 bushings are a hallmark of a properly built Nissan chassis. They offer zero deflection and predictable handling. Just be prepared for a difficult installation and a stiff ride.
The code P3180:97 in Nissan vehicles refers to a High Voltage (HV) Battery System fault. This diagnostic trouble code (DTC) is most common in Nissan hybrid and electric vehicles, such as the Nissan Note e-Power and Nissan Leaf . Symptoms
Turtle Icon & Electric Fault Icon: Appearance of these warning lights on the dashboard.
Reduced Engine Power: The vehicle enters a "limp mode" where power is significantly restricted.
No Restart Possible: The car may refuse to start after being powered off.
Power Loss While Driving: Sudden loss of power that may require turning the car off and back on to temporarily resolve. Common Causes
Faulty 12V Battery: A weak or failing 12V auxiliary battery is a frequent culprit for triggering various HV system codes.
HV Battery Internal Issues: High internal resistance or specific bad modules within the main traction battery pack.
A/C Compressor Failure: In some e-Power models, a short or fault in the high-voltage A/C compressor can trigger battery system errors due to electrical feedback.
EGR System Issues: A stuck EGR (Exhaust Gas Recirculation) valve can cause the engine to stop, subsequently draining the HV battery and triggering fault codes. nissan p318097
Coolant Issues: Low coolant levels in the inverter reservoir can cause overheating, leading to power reduction and system errors. Recommended Steps
The code P3180-97 (often associated with P3180) refers to a Traction Inverter fault or high-voltage system error commonly found in Nissan e-POWER models like the Note or X-Trail. This error typically triggers a "limp mode" where the vehicle loses power or displays a "turtle" icon. Understanding Code P3180-97
The Meaning: It signifies a fault in the inverter system or a high-voltage insulation leak to the chassis.
Common Symptoms: Sudden power loss, warning messages on the dashboard, and the car failing to restart or engage gears. Potential Causes: Faulty traction inverter. Internal high-voltage battery insulation failure.
12V battery issues or faulty generators in 2022–2023 models. Performance & User Experience (Nissan e-POWER)
Based on community reviews of vehicles that encounter this system, owners generally rate the driving experience highly—when it works correctly.
Driving Dynamics: The e-POWER system uses a gasoline engine purely as a generator, while the wheels are driven 100% by electric motors. This provides instant torque and acceleration (0–100km/h in ~7.0 seconds for the
Fuel Efficiency: Real-world fuel economy is cited around 4.5L/100km for the and approximately 7.1L/100km for the
Interior & Space: Reviewers from Reddit (CarsAustralia) and Reddit (NZcarfix) highlight "ridiculous" amounts of rear legroom and a high-quality interior, though some find the basic infotainment display lacking. Common Ownership Issues
Nissan P3180-97 refers to a specific Diagnostic Trouble Code (DTC) commonly found in Nissan Who is this for
hybrid vehicles (such as the Nissan Note e-Power). It is not a single "piece" or physical part, but a system fault code. Understanding the Fault Code System Issue : This code generally indicates a High Voltage (HV) battery isolation fault Safety Trigger
: The vehicle's safety system detects that high-voltage current might be leaking to the chassis or body. To prevent electric shock, the car is programmed not to start or may enter a "reduced power" mode. Common Symptoms
The vehicle will not start or "Ready" light will not appear. red car icon with a key or a "turtle" icon may appear on the dashboard.
The vehicle may get stuck in "Park" and refuse to change gears. Potential "Pieces" Requiring Attention
While the code isn't a part itself, it points to failures in specific components that may need inspection or replacement: HV Battery Computer (LBC/BMS)
: If the HV battery is deeply discharged, the battery management computer can "lock" (or "brick"), requiring a specialist to reset the dump or replace the unit. HV Battery Cells
: A leak or voltage difference within the internal cell stack can trigger isolation faults. Traction Inverter
: Damage to the inverter electronics can also cause this specific DTC. 12V Auxiliary Battery
: A weak or discharged 12V battery can often trigger false hybrid system codes during startup. Recommended Next Steps Do not repeatedly try to start the car
: If the HV battery is already low, multiple start attempts can drain it to a point where the battery computer permanently locks. Check the 12V battery Final Score: 9/10 (For Motorsports Use) The P3180-97
: Ensure your standard 12V battery is fully charged (ideally above 12.6V). Professional Diagnosis
: This code requires a high-level diagnostic scanner and an insulation tester to safely find where the high voltage is leaking to the ground. Are you experiencing a no-start condition , or are you looking for a specific replacement part to clear this error?
The error code P3180-97 on a Nissan (commonly seen in the Note e-Power or Leaf) typically indicates a High Voltage (HV) battery system fault. This code is often accompanied by the car failing to start or entering "limp mode" with significantly reduced power. Key Meaning and Causes
Isolation Fault: The code often signals a high-voltage insulation fault, where electricity may be leaking to the chassis ground.
Deep Discharge: It frequently occurs after the high-voltage battery (VVB) has been critically depleted, often because the gasoline engine failed to start and charge it.
Cell Failure: It can also indicate an error reported by the battery controller due to a "dead" or failed battery cell. Potential Solutions nissan note epower repair part 1
Note: In Nissan’s OBD-II system, the full code is typically P3180 (without the trailing "97"). The "97" often refers to a manufacturer-specific sub-identifier or a component location code. This article covers the standard P3180 code and its known applications.
Nissan P318097 is not a traditional OBD-II (On-Board Diagnostics) trouble code like P0301 (Cylinder 1 Misfire). Instead, it is a Nissan-specific engineering part number, sub-assembly identifier, or a calibration file reference number used internally by Nissan Motor Co., Ltd. and its suppliers (e.g., Denso, Hitachi, or Jatco). Based on structural analysis and Nissan's part numbering conventions, P318097 most likely refers to one of the following:
Crucially, P318097 is NOT a standard diagnostic trouble code (DTC). If you saw this number on a scan tool, it was likely misinterpreted from a raw data stream (CAN bus ID or calibration verification number), or it appears as a software part number in the ECU’s identification menu.
Nissan engineers designed this code to monitor starting system efficiency. Common root causes include:
