Signal Name Description Condition Impact Important
Controller Area Network (CAN) message received from the vehicle security controller (VCSEC) electronic control unit (ECU) has an invalid counter value, indicating an error in data integrity has been detected.
CAN message counter received from the VCSEC ECU does not increment as expected.
The VCSEC to Electronic Power-Assisted Steering (EPAS) interface is interrupted. Tire-based steering tuning may be affected.
No
Controller Area Network (CAN) messages received from the vehicle security controller (VCSEC) electronic control unit (ECU) has an invalid checksum value, indicating an error in data integrity has been detected.
CAN message received from the VCSEC ECU has an invalid checksum value.
The VCSEC to Electronic Power-Assisted Steering (EPAS) interface is interrupted. Tire-based steering tuning may be affected.
No
