The front view camera module disable history buffers are used to store information about the front view camera module features that are disabled. The buffers will only update if the disable condition changes.

Example: If the data received from the steering wheel angle sensor is Invalid across many ignition cycles then it will only appear in 1 history buffer and not all history buffers. If this condition is the current reason why the front view camera module is disabled then it will be set in front view camera module disable history buffer 1.
