Zapping the Volt

Some owners of 2011-2014 Chevy Volt vehicles may comment that the vehicle did not fully complete a charge or that charging was interrupted. A MIL may also be illuminated.

Technicians may find DTCs P1E00 set in the ECM and P0D3E or P0D3F are set in the HPCM2. The condition is known to occur with certain models of EVSEs (charge cords or charge stations) such as the Bosch Power Xpress (formerly SPX) and GE WattStation. This is due to an interaction of the diagnostics between the vehicle and the EVSE.

A P0D3F may also set if the vehicle was charging during a thunderstorm and the voltage dropped from the electrical grid during charging.

A new software package was released for the K57 Battery Charger Control Module (BCCM) to address this concern. Flash in the latest calibration for the BCCM.
