The "Ready Status" menu item indicates whether the OBD system has performed the required fault checks since the last time the 'fault memory was erased' or 'reset'. If a check proves to be OK, the one-off check is sufficient for a Ready status; if the system is faulty, the Ready status is achieved after a second check.

This is important, for example, for Inspection and Maintenance; this is where it is possible to detect whether the fault memory of a faulty vehicle was erased before the examination, without the cause(s) of the fault having been remedied.

The ready status is displayed for the following sub-systems:

Oxygen sensor heater
Oxygen sensor
Secondary-air system
Fuel tank ventilation system
Cat. conv. efficiency

Once the Ready status has been reached for a sub-system, this is stored until the next time the 'fault memory is erased'.

NOTE:

in some countries (currently: USA, Canada), it is necessary to restore the Ready status following manipulation of the DME before the vehicle is supplied to the customer.
To do this, you must perform the short test available in the 9588 Porsche System Tester II or a test drive to achieve the relevant diagnostic conditions (these are listed for each system at the beginning of the test instructions for P codes in this article).
If you have any questions, please contact your nearest importer.
