Circuit/System Description

The Battery Energy Control Module compares an expected value with a value reported from a Hybrid/EV Battery Interface Control Module. If the value does not match for a particular Hybrid/EV Battery Interface Control Module, then a DTC is set for the corresponding Hybrid/EV Battery Interface Control Module. This fault is internal to the Battery Energy Control Module and the Hybrid/EV Battery Interface Control Modules and no external circuits are involved.
