Diagnostic Aids

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

If the condition is the current reason why the frontview camera module is disabled, it will be identified in the Frontview Camera Disable History 1 parameter. If a new disable condition occurs, such as vehicle speed validity is invalid, the invalid steering wheel angle sensor fault will shift into the Frontview Camera Disable History 2 parameter and vehicle speed validity invalid will be in Frontview Camera Disable History 1 parameter. Since there are only four disable history buffers, the invalid steering wheel angle sensor will be cleared from the disable buffer if four other disable reasons occur since the last invalid steering wheel angle sensor event occurred. The Frontview Camera Disable History 1 parameter contains the current reason that one of the frontview camera module features is disabled.
