On the Diag. connector

To clear SIR codes.
Connect Pin A (which is ground) to pin K.
Turn ignition to RUN (don't start the engine).
Wait for the fault codes to begin flashing.
Unground Pin K for 3 seconds.
Again ground Pin K for 3 seconds.
Unground Pin K and wait 10 seconds.
Turn ignition off.
I look at an analog clock that has a second hand on it. When doing this procedure the ground and ungrounding of pin K has to within plus or minus 1/2 second. So you may have to try the procedure a couple of times before you can get the codes to clear.
Note: Codes 52,53 and 54 Can not be cleared. These codes indicate the air bag system has been deployed and the DERM must be replaced.
