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 Diagnostic Trouble Code (DTC) memory was erased or since installation of a new control module. After erasing the Diagnostic Trouble Code (DTC) memory, all testable values are set to "1" and then to "0" after successful completion of the test.
NOTE:
In the previous graphic, for generating readiness code, go to READINESS CODE, GENERATING .
NOTE:
The readiness code is only produced when all display digits in display zone 1 are set to "0".
If the specification "0 0 0 0 0 0 0 0" is achieved in display zone 1:
- Press < button.
- Check Diagnostic Trouble Code (DTC) memory to check. Go to DIAGNOSTIC TROUBLE CODE (DTC) MEMORY, CHECKING AND ERASING (there must not be any stored DTCs).
If specified value is not obtained:
- Generate readiness code. Go to READINESS CODE, GENERATING .
