Hello. I installed a new pioneer head unit into my 2010 Sentra a couple of weeks ago. No problems. I recently decided to add an amp and sub to the car and after disconnecting the negative battery terminal, proceeded to run all required wires.
After that was done (a couple of hours) I reconnected the battery WITHOUT any of the new wiring hooked up to anything except I added a remote wire and Metra NI-12 antenna adapter. I connected the blue wire from the adapter along with the remote wire for the amp (not even out of the box yet) to the wires from the head unit and the car for 12V ACC. I turned the key and deck lit up but reception was horrible. I moved it a bit and it turned off. I disco'd negative terminal and checked connections again. Everything fine. I reconnected deck lit up then turned off. Instrument cluster lights slowly faded to dark yet odometer reading faintly visible. I did not move the ground wire from where it was when the deck worked. Since then, the instrument cluster lights ONLY light up when speedometer is >0! Deck will not turn on at all.
All fuses are fine no obvious damage smoke smell etc. The eerie thing is cluster lights on only when car is moving. No other issues with other lights etc. Check engine light came on and occasionally gave five flashes which according to research is vehicle speed sensor.
I'm completely stumped! Any ideas are GREATLY appreciated! Also, is there a way to test the head unit to see if it's fried?
Thank you in advance.
