Thought I was good. Started securing wires, bypass, and r/s and found that now there is absolutely no r/s shutdown. Thought maybe I overstretched a wire from a connector, but all connections remain intact and have continuity.
I have proper startup via r/s, but no shutdown via remote, or brake press. Only shutdown is manually pushbutton on the Prius.
Also, if I r/s and wait the 12 min for the viper to shut it down, parking lights turn off but the vehicle remains running.
The brake relay is operating like it should and sending 12v inputs to both the r/s and bypass when the peddle is pressed. The bypass and r/s seem to "shutdown" but is not delivering the message to the car.
I have unplugged everything. Tried to refresh things with puting the key fob in and turning the vehicle on and off. Reflashed the bypass.
I'm suspecting the GWR output used on the viper's satellite harness is causing the issue. When "running" it's more like 2v+ than a ground. Like 9v+ when not running. Odd, but seems good enough to initiate a remote start.
If I pin a ground to either the r/s GWR output or the bypass side input GWR after a brake press or remote push, the vehicle will shut down. Pining a ground down the circuit past the diode on #85 to the relay does nothing.
With all this said, could the viper's GWR output be malfunctioning and not sending the proper voltage or grounding to the bypass' input for the shutdown?
Perhaps installing a relay powered off the GWR output that can cycle a wired ground to the rest of the circuit?
I have tried moving the circuit wire to the rear defogger output to see if I gained functionality back. The vehicle would start and then quickly shutdown by itself.
Wow. This install is a real PITA!
Afterthought side note.....
Shortly after my post says ago when I said everything was working like it should. I did notice some intermittent issues after every remote start where the secure take over worked and other times it didn't work and the car would shut down after the brake press. Seemed when I disturbed the wiring to the viper's GWR connector it would correct itself on the next attempt of a secure takeover. It definitely wasn't dependable at the time. When I thought it was good, that's when I started securing the wiring and modules when the gremlin decided to show it's ugly head.
