Maestro RR SU2 2016 WRX Pioneer AVH-W4400NEX No accessory signal

Post by W ARR X »

Flashed my Maestro RR and installed everything according to instructions. Radio is not turning on. There is no accessory signal going to the radio to turn it on. When I jumper from +12v power to accessory, it turns on and works. I stripped back the loom a bit to discover that the accessory signal (red wire) comes from the Maestro RR. I did a reboot on the RR and no change. What's my next step?

What is the LED light on the Maestro doing with the key in the on position?
Do we have power on the yellow wire of the 3 pin harness at the Maestro?
Reflash the Maestro to a Ford Focus and then back to your Subaru using the Weblink Desktop application downloaded from our website.
