4 OBD codes, solved the problems, perhaps! 700 1990

Bruce,

My understanding is in tune with yours. The ECU pulses the motor at a rate and duration to balance the inertia of the armature and spring return, providing a variable air gate. Pulsed signals are not easily analyzed with a DVM. Good application for that piezo buzzer.

However I only say this from experience in reference to LH2.4. The one Regina in my life continues to give my mother-in-law complaint-free "drive ability".

One important difference between Regina and LH2.4 controllers I think: LH2.4 has no non-volatile storage. You pull the power, its adaptive memory is gone. The Bendix controller has the ability to retain memory as we became aware of reading the "Regina Programmer" green manual. Not sure of what exactly is kept there regarding adaptive behavior.
