Readiness Code, Function

Readiness Code

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

The function of each of these systems is checked by On Board Diagnostic (OBD) and relevant position for system in 8-digit display is changed from "1" to "0" in a test sequence which must be fully completed .

The readiness code produced after successful completion of test sequence is then "0 0 0 0 0 0 0 0" (measured value block 086, display field 1).

If an individual test has been completed, but is "not OK", a DTC is entered in the Diagnostic Trouble Code (DTC) memory. Checking Diagnostic Trouble Code (DTC) memory. With Manufacturer's Scan Tool

The readiness code is reset to "0 1 1 0 1 1 0 1" if:
- Diagnostic Trouble Code (DTC) memory has been erased,
- Voltage supply to ECM has been interrupted (e.g. connector disconnected, battery disconnected).
- A new Engine Control Module has been installed

NOTE: When driving with varying loads the exhaust relevant tests are initiated by the control module and the readiness code produces itself. In this case the concluding control possibility is omitted, i.e. it is not obvious whether the vehicle was handed over to the customer without any DTCs.
