Description
The battery management system (BMS) did not receive a synchronous set of battery monitoring board (BMB) data through the BMB-over-CAN interface.
Potential Impact
The BMS performs BMB sensor data substitution to replace missing data from unreceived CAN frames.
Set Condition
The BMS does not receive an expected CAN frame containing BMB information within the task timeout period.
Clear Condition
All controller area network (CAN) frames containing BMB information are received at the expected task rate.
