BIT was developed for easy diagnosis, to display errors that occur during test procedures and internally. The idea is that a 2-6 digit error code will pinpoint the failure. This unique presentation allows a simple display of which error(s) are detected by the mower.
After a test is done (From the Service ⇢ Tests menus), if the test passed, “Passed” will be displayed. If failed, a “Failure xxx” number is shown on mower’s display. If it is between 201 and 227, look up its System Failure Error Code.
If you got an error code number, which could be 2-6 digits, and it is not a number between 201 and 227, contact customer support to get its meaning.
