Readiness Code, Function

The readiness code is an 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 "0". 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 DTC memory. Check DTC Memory.

When the readiness code is generated after a successfully completed test, "00000000" will be indicated.

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 re - generated.

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 whether all positions of the readiness code are set to "0."
