DESCRIPTION
Some customers may complain that the quick charging does not start or stops immediately when using specific charging
points. This may caused by the onboard charger not being compatible with some brand chargers.
NOTE: For reference, “EVTronic," and "Alpitronic” brands are reported as the inapplicable type of DC charger at this
moment.
To eliminate this concern, the control software of the onboard charger has been modified.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Reprogram the OBC with the Mazda Modular Diagnostic System (M-MDS), using the Mazda Diagnostic And Repair
Software (MDARS). Refer to MDARS ECU Reprogramming Procedure.
• If the current calibration file name in the ECU FILENAME screen is the same as shown in the Calibration Files
Information or with a later suffix, reprogramming is not necessary.
3. Clear the DTC, turn the ignition off, and get out of the vehicle.
4. Close and lock the door.
5. Wait for at least ten minutes.
6. Verify the repair by starting the engine and making sure the Check Engine light is OFF and no abnormal warning lights
are ON.
NOTE: If any DTC should remain after performing a DTC erase, diagnose the DTC according to the instructions on
MGSS.
