The monitors won't get ready until a Drive Cycle has been completed. Please click here to view/download the official Chrysler OBD-II Drive Cycle that applies to all 1996 and later light-duty vehicles.

You must drive the vehicle exactly as indicated by the procedure or the monitors will not get ready.

Also, please note that monitors won't get ready if there are any current or pending data trouble codes stored in the onboard computer.
