Readiness code: Notes

WARNING: This page is about a different car, the 2003 Audi S6 and 2002 Audi S6. However, it is still accessible from the selected car via links, so may be relevant.

The readiness code appears as an 8 -digit display on measured value block 086, display zone 1. Each of the 8 digits is allocated to a particular emission -related system.

If the function of these systems is checked by On Board Diagnostic (OBD) through a test which has to be run fully, the position in the 8 -digit display is set from "1" to "0". This happens regardless whether the test is performed with "OK" or with "not OK". This is under the condition that the test has been fully completed.

If a test is performed fully but with "not OK" a Diagnostic Trouble Code (DTC) is stored in the DTC memory. Checking DTC memory. See DIAGNOSTIC TROUBLE CODE (DTC) MEMORY, CHECKING AND ERASING .

If the readiness code is produced after the test has been run successfully it is also called "0 0 0 0 0 0 0 0" (measured value block 086, display zone 1).
