1. What does P3102 mean?
For Nissan Leaf models listed below, verified Nissan service communications instruct technicians to erase DTC P3102 after the applicable battery-ID loading procedure, then run the CONSULT “BATTERY GRADUAL CAP LOSS DATA CLEAR” work-support function.
2. Technical explanation
The supplied evidence does not establish a conventional fault definition for P3102. It documents P3102 within a Nissan CONSULT service procedure: after “LOAD BATT ID” is completed, the technician returns to EV/HEV Self-Diagnosis and erases P3102. The procedure then directs use of EV/HEV Work Support > BATTERY GRADUAL CAP LOSS DATA CLEAR, starting the procedure again when prompted and ending it after the status reads “Completed.”
3. What system is affected?
EV/HEV battery-related diagnostic and capacity-loss data functions. A more specific system name is not yet established by verified evidence.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
Not yet established by verified evidence.
6. Possible causes
- Not yet established by verified evidence. The supplied official communications place P3102 in a procedure involving battery-ID loading and clearing EV/HEV battery gradual-capacity-loss data, but they do not establish a root cause for the code.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
Not yet established by verified evidence.
9. What you can safely do
