Yes, the black mini usb goes from the lower console directly into the back of the head unit, by which I mean the radio with the touchpad on front. If you remove the head unit, on the back you will see both a black and brown mini usb. The black one is the lower console wire. I’ve had the cable...
The 2016 head unit was upgraded from the previous models. The closest thing on nicoclub is the 2016 Maxima. It has similar pinouts. BTW, if you are replacing the connecting mini USB cable or ports use the OEM ones for the LEAF. I fried a head unit USB function by using a different mini USB...
The Foxwell will show you both expected rpm and actual. Mine are close, maybe less than 10-20 rpm of each other, so I eliminated that as a cause. It didn’t give off much vibration either, which is why I thought that might be the issue, despite no DTC.
Yes, the Foxwell unit you have will show the pump activation and real time rpms, which is how I eliminated it as the issue on mine. I’m still going to check the continuity on the sensor. I saw on another post that if the sensor reads anything below -20F, it shuts the heater down to protect the...
Yes, I have done the same swap! The brown USB connector goes to the TCU and is unused in the 2013 since our 3G TCUs are boat anchors…..I still need to get the dealer to do the manual VIN update so some of the VCU data will display and I think it will clear the U1000-01 09 MULTI AV CAN Comm...
Do you get a DTC or set of them when the fuse is blown? I’m not getting any so I was thinking it might be a erroneous sensor signal rather than an outright sensor failure.
I am seeing the almost the exact same fluctuation. I was able to get my pump readings and it’s operating properly. My PTC only shows 50W draw, but I haven’t let it run long to see if that changes.
Let me know how your continuity tests go. I’m seeing similar results with a Foxwell, but my heater pump shows no numbers at all, which should throw a DTC, but isn’t. I might replace that and see.
Yes, pin 37 is positive. You can download the service manual from here:

The one for the hvac will give you the pinouts.
You can do a continuity test on the wires from the high temp sensor to pins 30 and 37 on the connector for the ac auto amp. I’d swap out the sensor first though, given the variation you described. The sensor should give a variable response when in use. It ranges from 4.7V at -20C to 1.27V at 80C.
Could you post the QY numbers for the units you swapped? It sounds like the non-BOSE motherboard won’t support the camera button functionality. I wanted to check before I went trying to attach the camera button radio frame to the non-BOSE unit to see if it would work.
