This system does not have a code 20, it uses codes 0 thru 8. It sounds like it might be in diagnostic mode. A constant 3 second flash with a 2 second interval between flashes indicates it is in diagnostic mode with no faults. Originally there was a fault with the fast flash. If it was a code 2, then that is for the drivers air bag circuit. In order to properly diagnose this you will need what is called an air bag simulator. You cannot test circuits with an DVOM or test light. Usually what causes this code is the air bag contact spring. I am attaching the self diagnostic procedure and the pinpoint test for code 2.
