Readiness Code

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.

During a test sequence which must be performed completely, On Board Diagnostic (OBD) checks the function of each of these systems and then changes the character assigned to it in the 8-digit indication from "1" to "0" once the test has been performed successfully.

When the readiness code is generated after a successfully completed test sequence, it reads "00000000" (measuring value block 086, display field 1).

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

Readiness code is returned to "0 1 1 0 1 1 0 1", if:
- DTC memory was erased
- Voltage supply to ECM was cut off (e.g. connector disconnected, battery disconnected)
- A new Engine Control Module (ECM) was installed

In this case, the readiness code must be re-generated. Generate Readiness Code

NOTE: During driving operation in various load conditions, exhaust relevant tests are performed by the control module and the readiness code is generated on its own. In this case, however, the concluding control possibilities are not available, meaning that it will not be indicated whether the vehicle is free of malfunctions upon transfer to the customer.
