interior light flash and no start

[tanik]

hey guys, I no this might not be the place to post for a 03 Nissan Sentra. But I was hoping it might be the same for the 240s and all other nissan.

But my sentra wont start having some major issue. the whole dash light and all other button lights are flashing on and off. and the car wont start, it wont even crank just nothing. I swap battery thought that was the problem but nothing. I found probably 2 popped fused and replaced them. It was and audio fuse and one battery fuse. I also had it checked and OBD code read U1001 and P0462(i found what this was) but not the U1001. Ive tried checking online and nothing really about it. Can some let me know if they had this issue before and what is the solution.

thanks.

Not sure if this helps or not, but inputing obd code u1001 into google (which you should have done by the way...) gives you:

"U1001....Controller Area Network (CAN) communication problem"

You would have better luck on the sentra forums considering most of the 240sx on this board don't have obd ii.

When did this start? Did you install some electronic equipment, then car stops working shortly after?

Well i did check on google but there wasnt any information on how to fix that. So i was wondering if someone had a problem like that before. I didnt install anything just one day the car started to make some funny buzzing noise and then the next day it wouldnt start. Started with a jumpstart and then it stopped and a jump start didnt help anymore. all it does is the dash light and all the buttons in the car just flash on and off everything 10-20 second.

check the alt fuse big 75a fuses

[tanik]

i cant find a 75a fuse in the car at all. the biggest ive seen for the car is a 40a. and how do you know if a relay is bad or not?

[pbcstylez]

look in the engine bay for the fuse box u have to have a 75 A fusible link

look in the engine bay for the fuse box u have to have a 75 A fusible link

Isn't that also the battery fuse (which he said he replaced)?

[tanik]

Ive looked in the engine bay and yes i did replace the battery fuse which was the 40a fuse. But about the relay how can one tell is it has gone bad?

Hey guys thanks for your help. But it turns out to be nothing with relays or fuses. I was looking for some fuse under the driver side and then i notice some strange clicking noise. and it was coming from the alarm system. I started to pull out all the cables from it and it stopped clicking but once i connected all the cables back it stopped and but it came back. then i took my alarm key and press unlock and it stopped the clicking. then i was able to start the car and then i put in the obd reader again and this time pass without error codes.

so if anyone is having the same problem check the alarm system.

thanks everyone.
