One more electrical oddity...

:
2012 Mazda5 Sport 6MT
On a few occasions while driving I've noticed that all of the warning lights in the instrument cluster will turn on, the instrument needles will swing to maximum and down to zero, and then everything will return to normal. There isn't any reduction in power or performance issues, just the lights and needles. Any chance that this could be due to the cheapo WiFi adapter I have plugged into the OBD2 port for communication between the car and DashCommand on my phone? I can't really predict when this will happen, so I'm reluctant to disconnect the adapter as I use DashCommand almost daily.


Thanks,
Ryan
 
Disconnect it for a fee days to see if it still happens. If it does, then its not the adapter.
