Protection Level Changed

Default definition: |  | ALARM + EXTERN + ACTIVE |
Used by block: |  | CPU |
Category: |  | MAINTENANCE |

A change in the protetion level of the system has been detected by the firmware on the CPU-D4 central processor board. The change could be either due to a removal of the FECU (Feature Enabling Control Unit) or due to a re-connection of the FECU and should not occur during normal operation. The protection level of the system is verified by the firmware on the CPU-D4 board every time, a supervision request is received from the central software.

- D1: Previous protection level
- D2: New (current) protection level
- D3: Type of dongle
- D4: Undefined

#### Recommended action

If the warning occurs during normal operation without manual interaction of a service technician, the FECU is probably damaged and has to be replaced.
