| Your Situation | Recommended Action | |----------------|----------------------| | | Your scan tool is misreading CAN data. Clear all codes, drive until readiness monitors complete, then rescan with a professional tool (e.g., Autel MaxiCOM, Snap-on, CONSULT-III). Ignore P318097. | | Saw P318097 as an ECU Calibration ID | This is normal. It means your ECU software is up-to-date for that version. No action needed. | | Heard a mechanic mention P318097 | Ask for clarification: Is it a software part number, a drawing number, or a misread code? | | Need to replace an ECU and the new unit shows P318097 | That is just the software ID. Reprogramming may be required to match your VIN, but the ID itself is not an error. | nissan p318097
