SSU - Last Exit Codes

Control Unit SPN FMI Last Exit Codes Description
SSU     None The system is just initializing - nothing has been checked yet.
SSU     Steer Whl Indicates steering wheel has been moved manually disabling/deactivating AutoTrac operation.
SSU     Too Slow Indicates vehicle speed is too slow, which causes AutoTrac to not enable/activate, or causes AutoTrac to disable/deactivate when active.
SSU     Too Fast Indicates vehicle speed is too fast, which causes AutoTrac to not enable/activate, or causes AutoTrac to disable/deactivate when active.
SSU     Reverse Indicates vehicle is in reverse. AutoTrac does not operate in reverse gear.
SSU     Track Indicates vehicle has wandered to a different parallel track number, which causes AutoTrac to disable/deactivate.
