Degradation eventually becomes Power Logger not connecting
Hi Eric - For a month or so my Scanmaster (with 2.1 chip) has been giving me flaky readings when driving. For example MPH would sometimes blink from (normal) 35 mph to 70 mph. Same momentary doubling for other SM parameters (like coolant temp, etc.). Two weeks ago, the SM started displaying nothing but all zeros. I bought a new SM, installed the 2.1 chip and it also read the same zeros. Therefore, nothing wrong with SM.
Today I connected my XP laptop to the PL. Just once the laptop displayed lots of wacky PL readings in monitor mode (like coolant temp at -130). But now the PL no longer appears at all in the laptop's device manager and of course there are no longer any data readings.
Plugging the USB connector in and out of the laptop does nothing. Tapping F8 creates a laptop beep. Now the SM reads SCN2.2, then PL, then the display extinguishes completely.
The only positive thing I can say is that the PL green light lights once at key on and the engine still runs. Isn't the green light supposed to blink about once a second when the engine is running? Mine doesn't. Is that a clue? Is the PL bad?
