I saw this on another post.... (that should be added to the Techinfo article) When I'm getting the calibrate message it doesn't want to let me set the zone or continue the calibration process. It'* like the DIC ignores my input.
If after three consecutive attempts to retrieve the current zone setting the cluster does not receive a valid response, the cluster will dash the zone number. At this point the driver may press the Reset button to change the zone.
That sound like what I'm seeing. At this point I'm seeing the -- and the reset button just flashes the --, no numbers. If I get the time this weekend I might disconnect the module and see what the symptom is.
