POWERTRAIN – CONCERN REGARDING EV MODE (PHEV)
Customerr Voice:
–
Customers will be reporting EV (Electric Vehicle) Mode not available when selected
by the driver, engine running when not expected, or ‘EV Mode not available’ warning
displayed on the screen.
Technicall Description:
–
–
–
Engine start is requested due to conditions of the Powertrain system.
The most likely cause is due to PCM Air-Fuel adaptions being incomplete. This can
happen post a PCM SOTA update or DTC clear event which results in the adaptions
being reset.
The PCM needs to see a variety of engine running conditions in order to re-learn the
adaptions, allowing EV Mode to function.
Status:
–
–
–
–
Please run the ‘PCM - Fuel Adaption Re-Initialization’ application in TOPIx.
Ensure the HV battery has sufficient State of Charge and then drive the vehicle,
periodically selecting EV Mode to confirm the concern has been resolved.
If the concern persists, then please refer to TOPIx workflow for further guidance.
The PCM application is available only for P6 PHEV powertrains. If the vehicle has a
P4 PHEV powertrain, the adaptions must be learned by driving the vehicle.
