The catayst monitor takes about 2 weeks to past readiness test.
The EGR should perform test durning de-cel every time that you drive UNLESS you are a 2 footed driver. You need to COAST downhill for 4-5 seconds with the engine at 1800-2000 RPM for the EGR test.
Also the secondary air-injection test needs about 10-15 minutes of driving & then setting at idle for 1-2 minutes.
