1. What does P0DAB mean?

For Mazda CX-70 and CX-90 vehicles listed below, P0DAB is identified in Mazda service communication SA-044-26 as a different issue that should be referred to SA-001/25. The supplied evidence identifies the description as “U0401:68 Error signal received from ECM (e-SKYACTIV PHEV)/PCM (except e-SKYACTIV PHEV), el.”

2. Technical explanation

Verified evidence links P0DAB to an error signal received from the ECM on e-SKYACTIV PHEV vehicles or PCM on non-e-SKYACTIV PHEV vehicles. Mazda communication SA-044-26 states that P0DAB indicates a different issue and directs technicians to SA-001/25. Earlier supplied communications for SA-001-25 and its revisions describe P0DAB:17 in the MHB module and P0DAB:00 in the SGC2/DMCM module in connection with a specified instrument-cluster message.

3. What system is affected?

The verified description references the ECM (e-SKYACTIV PHEV) or PCM (except e-SKYACTIV PHEV). The supplied evidence also references the MHB module and SGC2/DMCM module for specific P0DAB subcodes.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • An instrument-cluster message stating “Hybrid System Malfunction. Have the Vehicle Inspected” is described in SA-044-26 as occurring where P0DAB may be stored.
  • An instrument-cluster message stating “STEM AND i-STOP MALFUNCTION” is described in SA-001-25 communications when P0DAB:17 and/or P0DAB:00 are set.

6. Possible causes

  • An error signal received from the ECM on e-SKYACTIV PHEV vehicles or PCM on non-e-SKYACTIV PHEV vehicles is the verified diagnostic description.
  • The underlying cause is not further established by the supplied 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
