Hey fellas,

I put in some kenwood components in the front over the weekend. Now this Monday am I notice the check engine light is on. I've got a 2004.5 G35 AT with 5800 miles on it - last service at 2500 miles. I ran a scan tool and it reported a code of P0000. That does not mean anything according to the list I have (it starts at P0001).

Anyone have any insight?

Thanks!

 

not sure, i ran into the same thing after unplugging a harness and having the ignition on.
anyway, a quick ecu reset solved the problem for me and the cel never came back

 

Not sure what that code means. Did you have the battery disconnected during install? Or have the stereo on during any of the install?

 

I had the negative lead disconnected while I was actually installing, but after finishing each side, I reconnected and tested before putting the door panel back on (to save me the hassle of taking it off in cased I messed something up). Everything went fine - no glitches.

I hooked up the leads going to the tweeter (green/red wire serving as +/- respectively) to the Kenwood passive crossover and then used the two outputs of the crossover to hook up to the tweeter and woofer. I left the old woofer connector unconnected.

Sound ok to you fellas. It sure sounds ok with the radio on (though with the 4 ohm speakers, I have to crank it up a little more).

So yes, the stereo was on during the install, but not while I was actually plugging/connecting stuff in/out.

 

Swing by the dealer and have it reset.

 

IF you had the engine running for long periods of time while idle....the engine will throw a code...just drive it for a while and it will reset by itself....happened to me twice while do long installs/adjustments on electronics and letting the engine run while doing so

 

I would either just drive it for a bit or do an ECU reset. You couldn't have damaged anything as long as you only touched speaker wires.

 

Thanks for the responses. I found out that a code P0000 for our cars actually represents a "PASS" code - that is no error on self diagnostics. I can reset the light using my scan tool, but I think I will leave it on till I take for service next week. I am curious to see what the dealer comes up with using their Consult tool. I will let update this thread with what they say...

 

Update from Infiniti dealer.

The code is "E0001" (I think) - my scan tool did not get it - it reported the P0000. Anyway, their computer said that 21 "trips" (on/off cycles ago), the ECU backup battery discharged. This was almost exactly the time the car battery was disconnected for several hours while installing the speakers (I took a break in between to make an "adapter" to allow std 6.5" mounting).

So anyway, they said if it happened again, let them know, else it was just a weird glitch (I didn't get into telling them that I had purposely disconnected the battery).

So no worries it seems...
