'12 G37xs check engine light, abs, traction light (FIXED)
This got fixed at Infiniti of Louisville. They said one of the unified meter plugs was swapped with another plug. Weird.
I've been doing live updates during the install of my Phoenix Android Radio in the "Tesla Style Screen" thread. I've reached a point where I need help. This separate thread might help me reach a solution faster since it's not the Phoenix radio causing the problems I'm having now. Sorry if that's a problem posting the same info in two places. I just wanted the extra visibility to readers. 2012 G37xs Sedan, with nav, with bose, with backup cam. I was installing the Phoenix Android radio and hooked up the plugs to the " ACAmp (plastic box)" wrong. It created lots of weird symptoms (no engine start, backup lights on constantly, can't turn off power to the car without disconnecting the battery etc...) Well once I figured out what I had done wrong and corrected it, I developed a new set of problems. I decided to go back to factory until I can get in touch with Phoenix for help but the problem may not be on their end after all. The issues persisted even after factory radio install. 1. My check engine light is on (can't pull codes using Torque app and Elm bluetooth code reader) 2. ABS light is on 3, Traction light is on 4 Blower motor doesn't work 5. No paddle/slap shift 6. No turn signals 7. No factory backup camera 8. Air bag light blinking 9. Disk changer seems to making some kind of cycling off/on noise every 2 minutes or so Any ideas where to look? I've checked fuses twice now (fluke meter and manually pulling to look). I checked the fuse box behind the driver kicker panel and the one under the battery cover. |
Update: Got the codes checked and there are a lot. I've got a problem.
Transmission: p1815 Manual mode switch circuit ABS: c1109 battery voltage out of range U1000 CAN communication circuit BCM: U1000 CAN communication circuit U0415 Vehicle Speed Signal B2193 Chain of BCM - ECM B2553 Ignition relay B2557 Vehicle speed B2562 Low voltage B2601 Shift position B2604 PNP Switch B2605 PNP Switch B260A Igntion relay B260F Engine State Signal Lost B2617 Starter Relay Circuit B261A Push Button Igntion Switch C1729 Vehicle Speed Signal Error Multi Audio Visual (AV) U1217 Bluetooth Module U1229 iPod Certification Error TPMS: U1000 CAN Communication Circuit U0415 Vehicle Speed Signal |
Phoenix Android radios finally got back to me on Instagram. They said it should be a fuse and that I should check the Facebook group.
I've already been over every fuse under the hood and in the driver side kick panel with a fluke meter. Not sure what more I could do. |
no way to clear all those codes and see if they pop up again?

This is a stab in the dark, but have you tried reinstalling your factory system and, if so, what are the status of the codes?
I briefly checked the FSM and many of those codes/symptoms/systems have one thing in common: the wiring is, in some way, connected to the AC Amp. Additionally, some of those systems reference fuse #3 and fuse #7 and also the fusible links at the battery positive cable. Code U1000, the CANBUS com circuit, is almost always a result of a bad ground somewhere. I wish I could be of more help. At this point I would say to hell with the Phoenix unit- could be a bad unit or a incorrectly pinned harness... |

I tried replacing the AC Amp/Unified meter with a known good one from my friends car (same car except without navigation and bose but an Infiniti Master Tech tells me that shouldn't matter). That didn't help me. I haven't noticed or looked at the fusible links at the battery cable. I will verify those after work tonight now that I know to look there for them. I'm hesitant to hold Phoenix responsible or give up on the product because at the end of the day, I created this issue by plugging the wrong plug up to the AC Amp box. Better instructions with the radio probably would have prevented this but I take responsibility for my part. |

If/when you have the timex before taking it to the dealer, try checking ALL of the wires at the AC amp with your fluke meter. Just about every code you have is linked in some way to that damn thing. I know you said you switched with a known, working amp and there was no change, but there is something off in that area- I'm guessing a bad ground.
2012 G37 Sedan FSM Section MWI (Meter Warning Indicator) will have the spinouts for the AC Amp (wouldn't hurt to download the whole FSM while you can). |
