Mitsubishi P1019
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
P1019 is documented for the 2016 Mitsubishi i-MiEV sold in the United States. The verified Mitsubishi TSB instructs technicians to check whether P1019 is set in the EV-ECU and, if it is set, carry out DTC-specific troubleshooting.
This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P1019 mean?
P1019 is documented for the 2016 Mitsubishi i-MiEV sold in the United States. The verified Mitsubishi TSB instructs technicians to check whether P1019 is set in the EV-ECU and, if it is set, carry out DTC-specific troubleshooting.
2. Technical explanation
The supplied official TSB evidence identifies P1019 as an EV-ECU diagnostic trouble code checked during diagnosis involving the EV charging cable and main drive lithium-ion battery cable. The excerpt also directs measurement of resistance 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 supplied evidence does not establish a plain-language fault definition for P1019.
3. What system is affected?
EV-ECU; EV charging cable and main drive lithium-ion battery cable are referenced in the verified TSB 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 TSB excerpt references malfunction of the EV charger cable (quick charging) and malfunction of a quick charger, but the supplied evidence does not establish these as confirmed causes specifically for P1019.
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 qualified Mitsubishi EV service provider.
- Do not perform the TSB resistance measurement yourself; the supplied procedure includes a high-voltage danger warning.
10. Step-by-step troubleshooting
- A technician uses scan tool MB991958 to confirm whether P1019, P101A, P102E, or P102F is set in the EV-ECU.
- If P1019 is set, the TSB directs the technician to carry out troubleshooting for that DTC.
- If the listed DTCs are not set, the TSB directs measurement of resistance between the G-01 EV charging cable positive terminal and the G-19 main drive lithium-ion battery cable positive terminal.
11. When to contact service
Service involvement is appropriate because the verified procedure concerns high-voltage-system components and includes a danger warning.
12. What the service center may check
- Confirm EV-ECU DTC status using scan tool MB991958.
- Follow the applicable P1019 troubleshooting procedure if the code is present.
- Perform the specified cable-terminal resistance check only under the TSB's high-voltage service precautions.
13. Possible repair or resolution
- Not yet established by verified evidence.
14. Affected vehicles

19. Frequently asked questions
What vehicle is P1019 verified to apply to?
The supplied applicability evidence supports the 2016 Mitsubishi i-MiEV in the United States.
Does P1019 mean the EV charging cable has failed?
Not yet established by verified evidence. The TSB references EV charging cable and quick-charger malfunctions, but the supplied excerpt does not assign either as a confirmed P1019 cause.
Can I continue driving or charging?
Not yet established by verified evidence.
Can I test the cable resistance myself?
No self-service guidance is supported. The verified procedure concerns high-voltage components and includes a danger warning.
