Readiness code
The readiness code appears as an 8-digit display
in measuring value block 086, display field 1.
Each of the 8 digits is allocated to a specific
exhaust related system.
During a test sequence which must be performed
completely, On Board Diagnostic (OBD) checks
the function of each of these systems and then
changes the character assigned to it in the 8-digit
indication from "1" to "0" once test has been
performed successfully.
When the readiness code is generated after a
successfully completed test sequence, it reads "0
0 0 0 0 0 0 0" (measuring value block 086,
display field 1).
If a single test is completed entirely, but indicated
as "not OK", a DTC will be stored in DTC
memory. Check DTC Memory Page 01
