resolved, in many parts, but sufficiently different to warrant a different post, here.
(I have a 2000 9-5 turbo.)
In that prior post, I had a dealer replace a flooded Twice. I tore down the old Twice package, the electronic board was corroded in places [accounting for shorts and a dead battery and misbehavior before car death with the radio and messaging panel, as well as goofy cabin lights and more.] When I swiped the Twice's male connector pins with a rag, the rag came away with traces of corrosion [a blue, copper oxide color]
With the Twice replaced, when I drove off from the dealer, the radio did not work, at all, and provided no clues why. Today, a few days later, to my surprise the radio worked. And then, minutes later, gremlins returned, with intermittent notations about "radio locked". Other gremilin evidence: The radio would go off then on at varying intervals, without [or with, sometimes] a radio locked message. On restarts of the car, sometimes there would be a message to check the theft system, sometimes not. Or the car would report a brake light out, or suggest problems with rear lights.
For some reason, I vaguely remember that the mentioned non-radio items are also connected to the Twice [not Dice or other computer] -- is that correct?
I suspect a bit of corrosion on the female pins on the Twice connector on the car's wiring harness beneath the seat? How sensitive is the car to corrosion, there? What are the signal strengths on that bus/harness, connected to the Twice? Where can I go to read up about the various buses that are on that connector?.
Could the computer under the passenger seat be bad? Are any of the symptoms connected with corrosion of that device [a Dice???] or corrosion on the male/female pins, there, under the passenger seat? I was surprised that only one computer got bitten by the couple of inches in the car -- not the one under the passenger seat [there is one there, yes?] But then, the carpet was merely wet, a little, on that side, while the driver side had an obvious volume of water in the rear seat passenger foot well.
Thanks to all in advance.
