Last night started my car and the ABS, VDC, Brake, the Key, and the tire lights were all on. It drove and shifted just fine, but the speedometer read '0'. I got multiple codes from OBDFusion, but no check engine light. I've attached a screenshot of the codes. Any help, or point me in a direction to check would be greatly appreciated.

 

Have you googled the codes?

 

Bcm failure

 

Definitely looking like bcm failure. I'd take it to nissan and see what they say. You can also contact motorvate on here he may have more info. Really helpful guy

 

So it's looking like the BCM? That may explain a lot. Next scan had 12 codes and the CEL had now come on. P0500 - Vehicle Speed Sensor A. My battery voltage at the control module showed 10.8v on one scan so I got a new red top and just installed it. I've gotten numerous "Low Battery" warnings from the radar detector recently, so it was in the plans gearing up for winter. After battery install, down to 7 codes. Odd.

I installed a remote start and Navi bypass about 2 months ago. Worked great for those 2 mtns, but I'm going to look in the dash one last time at all connections and also follow the FSM and run as much of the tests I can (without a Consult III) for each codes diagnostic procedure. I get the feeling all these codes are kind of related (all need to know wheel speeds, etc, except perhaps the U1232 - Steering Angle Sensor Calibration). And if it the VSS failed I would think the CAN communication being interrupted would account for those codes. Not sure how that works exactly.

If I can't get anywhere before the weekend, then I'll take it in to Infiniti. I will update once I find the solution to help anyone who winds up with these same symptoms. Thanks, gentlemen, I appreciate the guidance... I didn't know where to start. I'm not used to all these gadgets and sensors (other car is a 2002 Grand Marquis, lol, but it runs like a champ). Thanks again!

 

Uninstall that aftermarket stuff. If not done right that could definitely be the issue

 

Very sound advice. That's exactly what I'll do tomorrow evening.
From the hours (and hours) of googling after work, I'm thinking it's more of a connection problem, than a failed module. Makes it hard to diagnose when similar symptoms appear for a myriad of problems. It's probably senseless to try, when a tech could scan and hone in on the problem area more quickly. But I need my car to get to work, and love a good puzzle, so I'm giving it a shot until the weekend. Appreciate the advice, PNW_IPL!

 

Updating the solution:
Well, I finally found it. The ABS Cont fuse in the IPDM box had blown. Wasn't even aware of what an IPDM was, let alone that it has fuses. Feel pretty foolish, but I've learned a lot about the G37 over the past few days. Got all the wiring diagrams and harness terminal allocations for the G37 if anyone ever needs to find a certain one, also.

Just adding this for the search function: So if your ABS, Brake, VCD and Steering Lock (key) light comes on, speedometer and odometer doesn't work, the power steering feels like it's lacking a bit and/ or the AC doesn't blow cold. U1000, P1212, P0500 or P0460 codes show together. Check the IPDM fuse box first!

 

Great news! Glad you didn't rip the alarm out
