Sorry
Have not been out in the garage yet today. Been doing financial planning issues this morning. I was also waiting for my "help" to be responsive.
This has been at least a five week effort with "various tries" with different cadence responses from the beeper, top operation light blinking and windows going down, etc. over time. But never a pump working....
Like I said, I have already done fixes on the trunk partition, battery, electric trunk lock verification and firing up the DRBII Emulator to see the state of the sensors and actuators. Hopefully, I cleared up some of the chafe.
So now with my "helper" and the DRB III running, I can now start systematically document the behavior as it sits today (but after I do one more manual sync effort)
If I am optimistic, one more manual sync effort might cure the problem.
If not, I will tally up the present symptoms and report them along with some "DRBIII results" documentation.
