Not neccessarily.  The bits go by so fast that the average voltage may not
change enough so show up on a voltmeter.

If you just want to know something was sent, connect a CAN line to a audio
preamp input.  Each message should sound something like a click.  If you ge=

nothing, then you know the bus lines aren't wiggling at all.  Do this test
on both of the CAN lines independently to make sure they are both wiggling.

Again however, without a 'scope, this is going to be quite a time sink.
