Issue:
The Electric Vehicle (EV) driving mode does not operate as expected when selected by the driver.
In some cases:
The EV driving mode will not be selectable
The engine will start unexpectedly
An ‘EV Mode not available’ warning will be displayed on the Instrument Panel Cluster.
Cause:
The most likely cause is due to the Powertrain Control Module (PCM) air-fuel adaptions being in an
incomplete state. This can occur following a recent PCM Software Over The Air (SOTA) update or after
clearing Diagnostic Trouble Codes (DTCs) stored within the PCM, which results in the adaptions being
reset.
The PCM needs to identify a variety of engine running conditions in order to re-learn the adaptions and
therefore remove the engine start request, allowing the EV driving mode to operate as expected.
Action:
Complete the ‘PCM - Fuel Adaption Re-Initialization’ application in TOPIx Cloud
Make sure the EV battery has sufficient State of Charge (SoC) and then drive the vehicle, periodically
selecting the EV driving mode to confirm the concern has been resolved
If the concern is still present, then refer to TOPIx Cloud Fault and Breakdown for further guidance.

NOTE:
The ‘PCM - Fuel Adaption Re-Initialization’ application is only available for P6 PHEV vehicles. For P4
PHEV vehicles, the adaptions must be learned by driving the vehicle. The drive cycle must include the
following scenarios:
Steady cruise at a continuous speed
Steady acceleration from a stationary position
Overrun periods where the engine has the opportunity to enter the ‘Fuel-Cut’ state.
