Readiness code
The readiness code is a 8 digit display in
measuring value block 086, display field 1. Each
of the 8 digits is assigned to a specific exhaust
related system.
If the function of these systems is checked via a
test by On Board Diagnostic (OBD), which is
successfully completed, then the position
assigned to this system will be switched from "1"
to "2." This occurs regardless of whether the test
is indicated as "OK" or "not OK" as long as the
test is successfully completed.
If a test is completed, but indicated as "not OK",
a DTC will be stored in the DTC memory. Check
DTC memory Page 01
-15
.
When the readiness code is generated after a
successfully completed test, "00000000" will be
displayed. (Measuring value block 086, display
field 1).
