Dreaded U1000 Code

just got the F-U1000 today and could not start the vehicle. Put in a new battery since I needed one anyway, no start or crank. Grounds are clean. Fuses replaced are in good order, no start or no crank. Now I am wondering if it is the TCM. I've put 170,000 miles on the vehicle after the first doing the coolant bypass mod at 10,000 miles. I do all regular maintenance. Any suggestions? Thoughts? I am going to tow to Nissan later tonight, since I have gone through all of the checklists that other posts have gone through. I need this vehicle up and running since my wife is pregnant and will be our baby shuttle. Thanks in advance.

If i remember correctly I got that once after overheating the trans. I had it cleared , changed out the fluid and its been fine since.

do you have any symptoms or is the trans still operating correctly?

I never had a no start/ crank issue associated with the u1000.

did you tow something lately or do anything that would have overheated the trans?

I have never towed, I have had high rpm issues where the tranny did not want to shift up to the next gear lately. But I don't think the vehicle's tramsmission overheated. I do drain and fills every 10,000 miles on the transmission fluid. I will try reconnecting the battery and checking fuses in the dashboard one more time. I'm leaning towards the tcm may have an issue, but I never had strawberry milkshake.

Has any work been done to your x recently? U1000 can be a lot of things.

Can't see a TCM not allowing an engine to start.

here's a youtube video that makes me wonder why no crank no start therefore TCM/valvebody.

Interesting. I guess it would be easy to see if you have a blown fuse. What about the relay swap for the IPDM?

It happened to me.

Not necessarily the tcm preventing starting but the lack of communication between the ecu and tcm.

So it just stops the flow of data in the chain? Nissan and their wonky electronics. I had a Maxima that had no fused protection to the ECM. JUmp starting was not a good idea. I had an older Infiniti that was known to be even worse on fused protection for the ECM. IACV, TPS, and the electronic motor mounts would all short the ECM.
