Mitsubishi P102F
ECU. Q: Is the DTC set? YES : Carry out troubleshooting for the DTC. NO : Go to Step 2. STEP 2. Measure the resistance between the G-01 EV charging cable (+) terminal and the G-19
Quick answer
P102F is documented in Mitsubishi service material as an EV-ECU DTC to be troubleshot when set. Verified applicability is limited to the 2016 Mitsubishi i-MiEV in the US.
This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P102F mean?
P102F is documented in Mitsubishi service material as an EV-ECU DTC to be troubleshot when set. Verified applicability is limited to the 2016 Mitsubishi i-MiEV in the US.
2. Technical explanation
The verified source is NHTSA-hosted Mitsubishi TSB-19-54-005, published March 13, 2019. Its EV-ECU diagnostic procedure instructs technicians to check for P1019, P101A, P102E, or P102F. If P102F is set, the procedure says to carry out troubleshooting for that DTC. The supplied evidence also references a subsequent resistance measurement between the G-01 EV charging cable positive terminal and the G-19 main drive lithium-ion battery cable positive terminal when the listed DTCs are not set. The evidence provided does not establish P102F's specific fault definition.
3. What system is affected?
EV-ECU; EV charging cable and main drive lithium-ion battery cable are referenced in the verified diagnostic procedure.
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 official procedure references EV charging cable connection/quick charging and quick-charger malfunction in the supplied source excerpt, but the evidence does not establish either as a specific cause of P102F.
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
- Have diagnosis performed by a qualified Mitsubishi EV service provider.
- Do not attempt high-voltage component service. The verified source includes a danger warning concerning service of high-voltage-system components and removal of the service plug.
10. Step-by-step troubleshooting
- A technician can use scan tool MB991958 to confirm whether P102F is set in the EV-ECU, as specified by the verified Mitsubishi procedure.
- When the listed DTCs are not set, the procedure proceeds to a resistance measurement between the G-01 EV charging cable positive terminal and the G-19 main drive lithium-ion battery cable positive terminal.
- The supplied evidence does not provide the complete P102F troubleshooting sequence, specifications, or pass/fail criteria.
11. When to contact service
Contact a qualified Mitsubishi EV service provider for diagnosis, particularly because the documented procedure involves high-voltage-system components.
12. What the service center may check
- Confirm P102F in the EV-ECU using scan tool MB991958.
- Follow the applicable Mitsubishi diagnostic procedure for P102F.
- If the relevant DTCs are not set, the documented procedure calls for resistance measurement between G-01 EV charging cable (+) and G-19 main drive lithium-ion battery cable (+).
13. Possible repair or resolution
- Not yet established by verified evidence.
