Note on display zone 1:

Display zone 1 is the most important. This display indicates which system has been checked by the self-diagnosis since the last time the fault memory was erased or since installation of a new control unit. After erasing the fault memory, all testable values are set to "1" and then to "0" after successful completion of the test.
