hey guys,, so i recently bought my Z a few days ago, today i was trying to see why the amp the car came with was not working. so i messed with it for a while .. i disconnected the negative terminal and everything and at the end i could not find out why it did not work. but thats not important to me.. what matters is that when i turned the car on the ses light came on.. so i took it to autozone and got this code: http://www.obd-codes.com/p0603.
what you guys think? is it something to worry about or an ecu reset would do?

 

It's just telling you the battery was disconnected for a while. Has something to do with retaining memory. Clear it and it'll go away.

 

alright thanks
