2011 Scion TC Maestro SW

Post by jMace » Fri Mar 02, 2018 1:40 pm


I just recently installed my SW unit and I'm positive I have connected all wires correctly. I counted the pins on the harness to determine the correct wires. I have the Blue/yellow wire from the C cable connected, as the wiring diagram had shown. For some reason, the only button on my steering wheel that I can get to work is the MODE button. Any suggestions as to what I may be doing wrong?

Check your purple/red wire. It's either got a poor connection to the wire in the vehicle, or it's connected to the wrong wire in the vehicle. Your volume +/- and Seek +/- buttons are all on the same circuit.
