I would like to know this as well - I thought that if you started
the motor with the A&B pins grounded, the ECM went into the 
field-diagnostic mode and the SES/MIL would flash quickly if in 
open-loop or like once per second if in closed loop.  It may also 
show rich/lean or something like that right?  What am I thinking of?
