I just started having an issue with my 2008 CX-7. The head unit and instrument panel have started rebooting when driving. The last time this happened, the TCS light also came on, though I cleared it by turning the wheel and restarting, as normal after a battery disconnect (and the battery is maybe 6 months old).

So I am pretty sure that there is a bad electrical connection somewhere, but I don't think its at the battery. Other Mazdas (though they tend to be newer than 08) have this issue, and it seems that there may be a bad connection at the Body Control Module. I am planning on hitting those with some electrical contact cleaner, but does anyone know whether there are other components I should check?

Also, no codes.

Thanks.
