Mitsubishi P1B0D
Return to Step 1. NO : The diagnosis is complete. TROUBLE SYMPTOM CHART M1549222500102 SYMPTOM PROCEDURES Inspection Procedure 1: The cruising range shortened. . COMMENTS ON TROUBL
Quick answer
P1B0D is documented in Mitsubishi i-MiEV service information for specified US 2012, 2014, and 2016 vehicles. The supplied evidence shows a diagnostic procedure involving DTC clearing, charging, and rechecking; if P1B0D returns, the procedure directs EV-ECU replacement after prior diagnostic steps. The exact plain-language DTC definition is not established by the supplied verified evidence.

1. What does P1B0D mean?
P1B0D is documented in Mitsubishi i-MiEV service information for specified US 2012, 2014, and 2016 vehicles. The supplied evidence shows a diagnostic procedure involving DTC clearing, charging, and rechecking; if P1B0D returns, the procedure directs EV-ECU replacement after prior diagnostic steps. The exact plain-language DTC definition is not established by the supplied verified evidence.
2. Technical explanation
Official Mitsubishi service-bulletin material filed with NHTSA instructs technicians to check whether P1B0D is stored/set in the EV-ECU. After erasing the DTC and charging the battery—using either a quick-charging gun or a regular charging connector depending on the procedure—the technician rechecks for the code. If P1B0D is no longer present, the diagnosis is complete. If it returns, the procedure directs a return to the initial diagnostic step. The supplied excerpts also state that an EV-ECU replacement is directed at an earlier point when P1B0D is present, followed by a confirmation check. The excerpts warn that CAN-bus faults can cause an incorrect DTC to be stored/set and instruct diagnosis of CAN-bus lines before this diagnosis. The specific initial diagnostic steps are not included in the supplied evidence.
3. What system is affected?
EV-ECU and CAN-bus diagnostic context are established by the supplied official bulletin excerpts. A fuller affected-system description is not yet established by verified evidence.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- The supplied Mitsubishi material includes a trouble-symptom-chart entry for shortened cruising range.
- The supplied evidence does not establish that shortened cruising range is uniquely caused by P1B0D.
6. Possible causes
- A CAN-bus-line problem can result in an incorrect DTC being stored/set, according to the supplied Mitsubishi bulletin excerpts.
- The supplied material lists low ambient temperature during charging and high-load driving operation in the shortened-cruising-range symptom discussion.
- A direct cause of P1B0D is not yet established by verified evidence.
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
- Arrange diagnosis by a Mitsubishi-qualified service facility.
- Do not attempt EV-ECU replacement or high-voltage-system repair yourself.
- Provide the technician with the stored-code details and charging circumstances if known.
10. Step-by-step troubleshooting
- A technician should follow the applicable Mitsubishi diagnostic procedure.
- The supplied procedures call for checking CAN-bus lines before this diagnosis because CAN faults may cause an incorrect DTC.
- The supplied procedures include clearing P1B0D, charging the battery with the applicable connector/gun, and rechecking whether P1B0D returns.
- The complete initial diagnostic sequence is not included in the supplied evidence.
11. When to contact service
Service evaluation is appropriate because the verified procedure involves EV-ECU and CAN-bus diagnosis and may direct EV-ECU replacement.
12. What the service center may check
- Check whether P1B0D is stored/set in the EV-ECU.
- Diagnose CAN-bus lines before this diagnosis, as directed in the supplied bulletin excerpts.
- Clear the DTC.
- Perform the applicable charging confirmation procedure and recheck for P1B0D.
- If the code returns, follow the bulletin's instruction to return to the initial diagnostic step.
13. Possible repair or resolution
- The supplied procedure directs EV-ECU replacement at an earlier diagnostic decision point when P1B0D is present, then requires a post-repair charging and code-recheck confirmation.
- If P1B0D does not return during the confirmation check, the supplied procedure states that diagnosis is complete.
- Whether EV-ECU replacement resolves every P1B0D occurrence is not yet established by verified evidence.

19. Frequently asked questions
What does P1B0D mean on the Mitsubishi i-MiEV?
The exact plain-language definition is not established by the supplied verified evidence. The official excerpts place P1B0D in an EV-ECU diagnostic procedure.
Can a CAN-bus problem trigger P1B0D incorrectly?
The supplied Mitsubishi excerpts state that a problem in CAN-bus lines can cause an incorrect DTC to be stored/set and instruct CAN-bus diagnosis before this procedure.
What happens if P1B0D returns after clearing and charging?
The supplied procedure directs a return to the initial diagnostic step. The provided excerpts do not include that full initial step.
Does the procedure mention a repair?
Yes. At an earlier decision point, the supplied procedure directs replacement of the EV-ECU when P1B0D is present, followed by a charging and code-recheck confirmation.
