1. What does P1D08 mean?

For a 2012–2013 Mitsubishi i-MiEV (US), DTC P1D08 is identified in Mitsubishi TSB-20-54-003 as “Load Connection Abnormal 12” in high-voltage circuit AB. The cited TSB directs replacement of the on-board charger/DC-DC converter if the DTC is set after the specified check.

2. Technical explanation

The verified source labels P1D08 as “Load Connection Abnormal 12” and associates it with high-voltage circuit AB between the on-board charger/DC-DC converter and traction battery. The source’s diagnostic decision states: if P1D08 is set, replace the on-board charger/DC-DC converter; if it is not set, treat it as an intermittent malfunction under Mitsubishi’s intermittent-malfunction procedure.

3. What system is affected?

High-voltage circuit AB, including the on-board charger/DC-DC converter connection to the traction battery.

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

  • The verified TSB directs replacement of the on-board charger/DC-DC converter when P1D08 is set. A more specific underlying failure cause is not yet established by verified evidence.
  • If P1D08 is not set during the TSB’s specified check, the TSB identifies an intermittent malfunction.

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 EV service facility.
  • Do not attempt inspection, disconnection, or repair of the high-voltage circuit or traction-battery cables yourself.

10. Step-by-step troubleshooting

  1. The verified TSB instructs a check for whether the DTC is set after the specified regular-charge procedure.
  2. If P1D08 is set, the TSB directs replacement of the on-board charger/DC-DC converter.
  3. If P1D08 is not set, the TSB directs use of Mitsubishi’s intermittent-malfunction procedure.

11. When to contact service

Service is recommended because the cited procedure involves high-voltage circuit AB and replacement of the on-board charger/DC-DC converter when the DTC is set.

12. What the service center may check

  • Perform the TSB-specified regular-charge check and determine whether P1D08 is set.
  • Follow the TSB decision path for a set versus not-set DTC.
  • Use Mitsubishi’s intermittent-malfunction procedure when the DTC is not set.

13. Possible repair or resolution

  • When P1D08 is set, Mitsubishi TSB-20-54-003 directs replacement of the on-board charger/DC-DC converter.
  • When P1D08 is not set, the TSB directs intermittent-malfunction handling rather than identifying a component replacement in the cited evidence.
