Two similar projects on similar modern cars, no working speed-o and warning lights flashing. No one has pulled a code from the ECU? Please check for codes and post back if you can.
FSM - TM chapter states that the estimated vehicle speed signal is transmitted from the ABS actuator and electric unit, so having possibly messed up your ABS could have an effect on your speedometer. I pulled the one for 2009 and am looking at page TM-353. Now, I didn't dig real deep and I only looked at the 2009, but that should be similar for both of you. I do see info for the CVT in there as well. So, look around the FSM stuff and see if you can't find what you're looking for.
