So somehow the fuse burnt out for the gauge cluster and i only drove a couple miles till it got fixed. Then i was driving down the road and the car basically stalled when i tried to give it gas but would rev in neutral fine. Then it died so i pulled over and it acted like the battery was dead. Got that checked and replaced now its throwing 3 codes. One is for the fuel level (im guessing since the pump loss power it ran out of gas and throwing this code). Second code is for the vehicle speed sensor and the third code is manafacturer specific u1001. So can anyone help me out? It drives fine but i want to get these codes off

 

"U1001 CAN COMM CIRCUIT

ECM cannot communicate to other control
units.
ECM cannot communicate for more than the
specified time."

try google...."""u1001 g35 code"""

 

So could that u1001 code could have been because the cluster was out for like a day huh? How do you reset the codes? Is it just like any other car where you unhook the battery or is there a special trick to it?

 

So if i unhooked the negative side of the battery and pumped the brakes a few times should that get rid of the CEL code or do i have to follow th full ecu reset procedures i found on the web? I was going to use the guide i found on techno square for the 350z but wanted to make sure it would be worth all the trouble

 

disconnecting the battery would be the easier of the two although IMO, pumping the brakes only uses any lingering current within the car. I would leave the battery disconnected for a good hour or so, even overnight if possible. If that doesn't work, you can always try the pedal method or vice versa.

 

I diconnected the battery and pumped the brakes like 20 times so in total the battery was only disconnected for about 1 or 2 minutes. But it didnt clear the cel it still had the codes stored when i just turned to key to the on position. So do i need to leave the battery disconnected longer, or should i try the pedal reset way, or did i just not fix the problem and the light is still on? I mean when i disconnected the battery the radio presets are gone but im not sure if that means the ecu should have reset
