Readiness Code, Function

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.

If, due to a test which needs to be completed, the function of these systems is checked via output DTM, the position allocated to that system in the 8-digit display is switched from "1" to "0" if the test is completed with "OK".

If a test is completed, but indicated as "not OK",a DTC will be stored in DTC memory. Check DTC Memory

When readiness code is generated after a successfully performed test, it reads "00000000".

Readiness code is reset to "11111111" if:
- DTC memory was erased.
- Voltage supply to ECM was cut off (e.g. connector disconnected, battery disconnected)

In this case, readiness code must be regenerated. Readiness Code, Generating

During driving operation in various load conditions, exhaust relevant tests are performed by the control module within a "short trip" and readiness code is generated on its own. In this case, however, concluding control possibilities are not available, meaning that it will not be indicated that all positions of the readiness code are set to "0".
