Readiness code

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2003 Audi S8, 2003 Audi A8, 2002 Audi S8, 2002 Audi A8, and 2001 Audi A8. However, it is still accessible from the selected car via links, so may be relevant.

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. See DIAGNOSTIC TROUBLE CODE (DTC) MEMORY, CHECKING AND ERASING .

When the readiness code is generated after a successfully completed test, "00000000" will be displayed. (Measuring value block 086, display field 1).

The readiness code will be reset to "1 1 1 1 1 1 1 1" if:

The DTC memory was erased
A new Engine Control Module was installed

In this case the readiness code must be generated. See READINESS CODE, GENERATING .
