Answer below assumes the throttle actuator on the E420 is very similar
to the E320.
By test you mean what? The unit itself will go through a self-test
every time the key is turned on. YOu can usually hear the throttle
motor winding through its full movement every time you turn the key.

and will not show up with the built in LED.
Just in case someone else is listening in, here's one of the best code
summaries I've seen along with a link to
I wish mbz was more like Chrysler in that respect.
Turn a Mopar ignition on,off,on,off,on and the old cars would flash
