Function
The readiness code is an 8-digit number code which displays the status of the emission relevant diagnostic.
When the diagnostic for a system (e.g. secondary air system) has been successfully completed, the corresponding position in the number code will change from 1 to 0.
The diagnostic is performed at regular intervals during normal driving. It is recommended that the readiness code be generated after performing repairs on an emission relevant system, to guarantee that these systems function correctly. If a malfunction is detected during the diagnostic it will be entered in the DTC memory.
Each time the DTC memory is erased, the readiness code will be erased.
