Hello all,
While attempting to install a new head unit into an North American 09 LB, I think I may have blown the/an ECU. Here are some of the variables I'm working with while trying to diagnose the exact problem:
-Everything works but the car will not start, starter clicks very rapidly like no other dead battery I've encountered. Think I will have it tested anyway. I also jumped it.
-The head unit in question is a Pioneer AVH-X8500BHS. The harness was professionally soldered and shrink wrapped by a friend, with one catch. I ordered a kit on amazon used to bypass the requirement of the parking brake in order to watch video while moving (i just wanted the option, i would not drive while watching a movie). I lost the instructions, so we had to guess where 2 of the 3 wires went. Obviously black to ground, but we guessed blue to blue, light green to dark green. I think this is where we may have shorted something out.
-I checked "most" fuses, but was in a rush and feel I need to check again. EFI fuses were good.
-What I believe is the nail in the coffin is when I tried to scan for error codes, my scanner only states linking error. Perhaps it may be a burned out wire, but shouldn't the fuses prevent a wire from burning? I smelled no burning. If it is the ECU, where exactly does that leave me? I know they are cheap but will need to have some sort of dealer work done on them.
-Thank god I still have my MR2 to get me places.
Thank you all for any input.
