Flashing dash when engine is OFF

[klej89]

I found the solution to my problem.
On pin 1, black wire, plug right (power supply of meter after ignition) appeared voltage when the engine was turned off.
12 V when the plug was pulled out.
8-7 V when the plug is connected.
Unfortunately, the power scheme does not agree with the "2007 Yaris Factory Repair Manual", probably because I have a start-stop system.
I cut off the old wire and connected to pin 1 new wire supplied directly from the IG2 relay (15A fuse AM2). For now everything looks good.

Pin 1 should be ignition switched power, even on your European Yaris with start/stop. With that wire having some power on it when the car is powered off, I would be concerned about something dragging the battery down, when it should not be drawing current.

Do you have any aftermarket electrical system modifications?
