Description
Drive Inverter (DI) brake command message DI_brakeCommand checksum is incorrect.
Potential Impact
The IDB may internally generate and actuate brake torque requests as a function of brake pedal stroke, and actuate External Brake Requests (EBR) in response to DI_brakeTorqueCommand instead of DI_brakeTorqueCommandFull.
Set Condition
The IDB receives the DI_brakeCommand CAN message with incorrect CRC for longer than 100 milliseconds.
Clear Condition
The Integrated Dynamic Brake (IDB) receives the DI_brakeCommand Controller Area Network (CAN) message with correct Cyclic Redundancy Check (CRC) for 100 milliseconds.
