lock-out/back-up lamp switch or engine speed signal or vehicle speed signal or closed throttle position switch or safety relay in EA/CC/ISC control module
Out of desperation, I replaced the remanufactured unit with a known working
unit pulled from an identical fully functional vehicle. Idle speed/cruise
control now work properly. So far, there is no indication of intermittent
failure.
Returned unit to Beckmann for testing, they confirmed reman unit was defective. (the drive motor was bad)

Tnx for posting that . . .all info is good info.
A suggestion to DTC posters is to use the
NAME of the module being read from the PIN. . . . not just the pin. The reason is simple: In a E320 the diag connector's pin layout is different from that of a S500; 16 vs 38 pins. By talking "function", all confustion is eliminated.
