Scenario: I have an instrument track with Battery on it, and the drums I'm using are routed out to their own audio tracks from Battery. I'm using the step sequencer to create drum clips on the Battery track. Everything sounds great. 

So then I decided that I'd rearrange the rows in the step sequencer so that the 6 drums I'm using are all next to each other, and rename them to their proper drum names as well. I didn't know, however, that this only applies to the clip you're editing, and not all clips on the track. I would basically have to go through that whole rigmarole on every clip on the track. Not good. 

So then I figured I'd use a drum map. My first time using them. So I select the Battery track, select "MIDI" in the inspector, and assign the relevant drum map in the output (Sonar having the appropriate Battery drum map as a preset). The rows in the step sequencer are now named properly. 

But now, for some reason which completely baffles me, the step sequencer is not playing the Battery drums. Oh no. It has decided that things would be altogether a lot more fun if it applied the step sequences to a completely unrelated bass track instead. So now my bass track is playing a series of tuneless notes (i.e. the notes in the drum step sequencer clips) as well as the MIDI notes on its track. How is this possible? How could applying a drum map to my Battery drum track suddenly route the notes on it to another (seemingly random) track? 

I use drum maps all the time, but I never use them with instrument tracks - I never use instrument tracks.  I always create an audio and a midi track for each synth.

Using drum maps on separate audio/midi tracks has never given me any problems whatsoever.

Can you try splitting the instrument track into a separate audio and a separate midi track?

And, independently of your issue, I have 1 midi track set up for pointing to my drum map, and I use a custom kit in Battery 3 with each drum cell getting assigned to a different audio output, and then I have separate audio tracks for each of the drum cells in the kit.  This gives me the ability to completely control relative volumes, panning, and effects for each drum and cymbal.  Once I set up a project with this mapping, I saved it as a project template so I can load it all up at once without having to duplicate any of the effort.  It works pretty well for me.  Just a thought.

I tried splitting the track and assigning the drum map to the output of the MIDI track, but am still getting the same results. The MIDI is still triggering notes on the bass track. To be honest I don't think it makes a difference if you do it on an instrument track or a separate MIDI track - the MIDI and Audio tabs at the bottom of the inspector let you access the inputs and outputs of each part of the Instrument track pair exactly as if you'd split them. 

The trouble with me making Battery templates is that I like to experiment with a wide variety of kits, and some of the more exotic ones have wildly different mappings of course. Having said that it's so easy to set up the multi outs from Battery - considerably easier than it is with Kontakt for example. 

One of the purposes of Drum maps is to allow routing different note numbers to different ports, physical or virtual. Did you make sure to set the output port to Battery?

^^^^ What Dave said - Sounds like the drum map itself is set to the wrong port. Open the manager and assign the output port to the Battery. Holding down ctrl + shift while changing one will change them all.

Well slap my butt and call me Judy! That fixed it....thanks guys. Have never used the DMM before.

Okay then Judy!!  Glad you're sorted.
