proper prodedure for clearing DTC's from ECU memory
What is the right way to erase the fault memory on the ECU? I know I'm supposed to pull a fuse or fuses, but which one(s)? I've heard that I can pull either the clock/radio fuse, OR the ECU fuse. Will both of them erase the fault memory?
Do I pull the fuse with the ignition turned on? or off? Will it hurt the ECU if the fuse is pulled while the ignition is on? Hopefully someone knows this. Thanks

remove the clock/radio backup fuse and reinstall with the ignition off.
you can damage the ecu if you do this with the ignition on according to the Helms manual.
the fuse labeled "ECU/ECM" will do nothing. that only controls main power to the ecu. the backup power fuse is the one that will cut auxiliary power for memory erasure.
