[Ovmsdev] Not processing canbus frames anymore

I have a v3.3 module in my Corvette and recently got it back on the road 
but I find that following the sim7600 modem testing I did a few weeks 
ago, it doesn't seem to be processing canbus frames. When the car is 
running, the module does not appear to update soc or vin although this 
used to work.

Comparing "module sum" between it and my Cadillac turned up something 
extra in the [vehicle] section:

    [vehicle]
      12v.alert:

-    type: CHEVROLET_C6_CORVETTE
      units.distance: M

While the [auto] section only has expected differences:

I don't really remember/know how to quickly monitor the canbus but with 
the car running it *seems* to be seeing canbus frames:

     OVMS# can log start monitor crtd
     CAN logging to MONITOR active: Type:monitor Format:crtd(discard)

     Note: info logging is at debug log level, frame logging is at 
verbose, and errors as usual

Any suggestions on how to figure out what I'm doing wrong?
