Quick answer

P1A17 is documented in Mitsubishi i-MiEV EV-ECU diagnostic procedures. The supplied verified evidence does not establish a plain-language fault definition, severity, driving status, charging status, or a specific repair.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P1A17 mean?

P1A17 is documented in Mitsubishi i-MiEV EV-ECU diagnostic procedures. The supplied verified evidence does not establish a plain-language fault definition, severity, driving status, charging status, or a specific repair.

2. Technical explanation

Official Mitsubishi diagnostic material instructs a technician to erase the DTC, cycle the electric motor switch through specified positions, and check whether P1A17 returns in the EV-ECU. If P1A17 is stored/set again, the procedure directs a return to Step 1; if it does not return, the diagnosis is complete. The supplied evidence also cautions that a CAN bus-line problem can cause an incorrect DTC to be stored and instructs that CAN-bus diagnosis be performed before this diagnosis.

3. What system is affected?

The DTC is checked in the EV-ECU. The diagnostic excerpts reference the electric motor unit and main drive lithium-ion battery section. A more specific affected system 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

  • A CAN bus-line problem may cause an incorrect DTC to be stored, according to the supplied official diagnostic material.
  • Any additional cause of P1A17 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 qualified Mitsubishi EV service provider.
  • Do not perform high-voltage component or wiring repairs yourself.

10. Step-by-step troubleshooting

  1. The official procedure checks whether P1A17 returns in the EV-ECU after the DTC is erased and the electric motor switch is cycled through the specified OFF/LOCK, ON, and temporary START positions.
  2. If P1A17 returns, the official procedure directs the technician to return to Step 1.
  3. If P1A17 does not return, the official procedure states that diagnosis is complete.
  4. The supplied material says CAN-bus diagnosis should be performed before this diagnosis because a CAN bus-line issue can store an incorrect DTC.

11. When to contact service

Service is recommended because the documented procedure requires EV-ECU DTC confirmation and CAN-bus diagnostic consideration. Service-required status is otherwise not yet established by verified evidence.

12. What the service center may check

  • Check P1A17 in the EV-ECU after clearing the DTC and performing the documented electric motor switch cycle.
  • Determine whether P1A17 is stored/set again.
  • Perform CAN-bus diagnosis before this diagnosis, as directed by the supplied official material.
  • Follow the applicable Mitsubishi diagnostic flowchart when the code returns.

13. Possible repair or resolution

  • Not yet established by verified evidence. The supplied excerpts document verification steps and a return to Step 1 when P1A17 returns, but do not provide the complete repair outcome.
