That's a computer issue if I've ever seen one.
if I recall you can unplug the battery to reset the ECU. |

Have you installed a remote starter, alarm system, fog lights, or anything else which would have required tapping wires? The automatic transmission shift supplies a signal to the ECM indicating what position it is in. It is a simple switch that in each position directs a +12V signal to a different wire and the ECM has a pin for each shift position.
If I had to guess, I would say that somehow the brake switch or tail light feed got joined to one of the shift selector output wires and is confusing the ECM. |

If the problem just started, and the alarm has been installed for that long, I would look for a damaged or pinched wire. You would need to take the center console out to get at the connectors on the shift lever.

This is a mighty hard one to diagnose remotely. What does the battery voltage measure before and during the these events?
Also, which automatic transmission does your Yaris have? |
