its say reverse light not on canbus,

When the list was written it was assumed by the author that they aren't on the canbus as no warning messages appear on the dash.

But when there is a diagnostic test run on the car there will be an error code stored on the BCM for them so they are being monitored by canbus.

But as they don't put an error up the dash then there is nothing to worry about and hence why it's been left on the list.
