Circuit/System Description
When the battery energy control module is flash programmed, the hybrid battery interface module operating software and calibrations are provided to the battery energy control module. The hybrid battery interface module software and calibrations are then loaded to each of the hybrid battery interface modules from the battery energy control module. This operation is automatic and requires no operator action. At this point, if any of the hybrid battery interface control modules are not programmed correctly, the appropriate DTC is set.
This fault is internal to the hybrid battery interface control modules and no external circuits are involved.
