IETMS was (and still is) disabled.

 

Dawg, I just went through my historical codes again and lo and behold here's what I found:
U1040
Which is:
Loss of ABS serial data
8
2.3 DTC U1016,U1040,U1064,U1097,U1255
You many remember that I submitted a post about my rear brake bleeding down during this trip. Funny thing is, it went out 24 hours after this incident (when the check engine light illuminated).
Question: the trouble codes are listed on the speedo readout under their respective areas. P S SP t and b, respectively. My code, U1040, was under the "SP" area. Which is "speedometer." I'm not sure I quite understand that. Also, the fact that each code is prefaced with either a B, C, P or U. Can you shed any light on this for me? Much appreesh...

 

Here's the link to the post about my rear brake (and my radio!).
