I did a few a/v mods a couple days ago, and followed the owner's manual procedure so that I didn't mess up my windows/doors. I had the ground connection disconnected on the battery for extended periods of time. I didn't think anything about it. After about 2 off and on days of working on the Z, I reconnected the ground, got into the car, and checked the guages (did not start the car) and closed the hood.

The snow here finally melted, and the roads cleared up, so I decided to drive the car today. Here is my problem(s):

Service Engine soon light is on (not flashing)
Check tire light is on, and is displaying a tire problem
None of my tire pressure monitors are working (displaying ---)

I think everything else is working properly, and the car is running fine, jsut like it was before my work started. I have consulted the FSM for advice, and I can't find out how to disgnose any potential problem with the tire monitor system without a CONSULT-II diagnostic machine. I read in the FSM that the tire pressure sensors have to be registered, and essentially tuned to the tire pressure system in the Z. I assume that this is the problem, but I am still concerned. I know that I didn't do anything to create the problem other than just disconnecting the battery terminal.

Has anyone else experienced any similar issues to this ? No where in the FSM is there any mention of losing any settings, or causing the tire monitor system to fail. I have yet to find a means of resetting the system either, but I would prefer to not have to go to the dealer and say that I may have caused the problem by disconnecting the battery.

Does anyone have any thoughts or ideas ???

 

Go immediately to you Nissan dealer, and have the problem resolved. If disconnecting your battery for a few day is a problem, we would all like to hear abotu that. Please re-post with the fix.
