Code Cause Operation Reset Procedure

The document lists various error codes, descriptions of the issue causing each code, how the system operation is affected, and procedures for resetting or correcting the problem. The errors relate to communication failures, short circuits, open circuits, out of range voltage levels from sensors and components, incorrect speed sensor readings, issues with the fuel sensor, and abnormal alternator voltage levels. Many of the errors will reset automatically once the underlying problem is addressed, while others require manually turning the start switch after fixing the issue.
