Description
Invalid Pedal Monitor (PM) PM_state2 message or Drive Inverter (DI) DI_brakeCommand message received.
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 did not receive the PM_state2 CAN message for more than 200 milliseconds or DI_brakeCommand message for more than 100 milliseconds, had a checksum, counter, or message length error, or had signals transmitted as invalid.
Clear Condition
PM_state2 and DI_brakeCommand Controller Area Network (CAN) message integrity checks pass after the Integrated Dynamic Brake (IDB) is power cycled.
