8200nex maestro rr

Post by mpittman » Tue Jul 24, 2018 1:52 am

I've had my maestro rr and pioneer 8200nex over a year with a flawless record until last sunday. Jumped in my 2016 wrangler and headed out for a movie and about five minutes in head unit loses all power so I pull over and restart the jeep and it powers on and a few minutes later it died again so I just ignored it and went on with my day. I'd stop for an errand and it would fire up everything worked and a few minutes later shut down. So after work today I rip the dash apart to look for loose connections and I cant find a single loose or frayed connection I button it all back up and head out and it does the same thing but the maestro is dead. I unplug the power to it and plug it back in and it boots back up but a minute later it does it again. I drive home and grab my volt meter and it has power to the unit but doesn't give power to the head unit so is it toast or should I try to reflash it?

Which wires were you testing on the Maestro?

yellow going into the maestro had 12v but nothing coming out the other side at the harness going into the radio, and it only happens while driving. I can sit in the driveway for an hour and it wont shut off (or I've not experienced it yet.)

that's odd because they are tied together in the harness. i'd start by checking at the connection point in the harness. you will have to remove the tape to see it.

So there is 13 volts at the yellow wire of the maestro and 13 at the back of the radio and 13 at the factory harness and I have given it ground but it seems like the module just shuts down randomly for some reason. I’m gonna try to Reflash it and see if that fixes it but I can’t imagine it would. Any suggestions?

reflashing wouldn't be a bad idea, there have been some updates since you originally installed the RR.

can you check voltage on the yellow constant and the red ACC wire as well when power is lost.

When it dies there’s 13v on the yellow and nothing on the red wire. And the box is just dead, no lights or nothing so I don’t know what else it could be because I’ve checked the entire harness and there are no loose wires or shorts so the only thing I can think of is the maestro is shutting down for some reason and thus the radio shuts down.

justa as a next step are we able to pull the MRR from the vehicle and reflash it. First flash it as a ford 150 then back to the Wrangler. report back
