Circuit/System Description

WARNING: This page is about a different variant/trim than selected.

The hybrid powertrain control module continuously monitors the system voltage on the Ignition voltage circuits. The hybrid powertrain control module is located within the drive motor generator power inverter module and is not serviced separately. A higher than normal voltage may cause the control module or sensors to operate improperly.
