Maybe I'll have better luck here since I didnt get any replies on the sedan section and I believe 03-04 coupe and sedan clusters are the same. I installed . 04 cluster on my 03 G and now the vcd off light is on all the time but disappears when the parking lights are turned off but when you hit the vcd switch it doesnt show on/off on the cluster, light wont show up at all unless the parking light or headlight switch is in the On position. Anyone know what it could be?

 

You might post this in the A/V/Electronics section and see if Wrathernut can answer it (or maybe PM him). He's more stereo oriented but still has a deep electrical knowledge. TunerMax might be another person to ask.

I, myself, have no clue.

 

Thanks will do

 

That really sucks. One unfortunate thing is that the cluster's in our cars are highly integrated into the entire system. This means, you need one from pretty much the same car with all the same options.

In a lot of cars, you simply need to get one that is Automatic, or manual, to suit, and obviously wired roughly the same.

Nissan likes to make a billion mid-model changes though, and them changing a BCM (body control module) for instance could screw this up. BCM's for instance, commonly change depending on model, options, year, manfuacture date, and so forth.

I will try and find some time to get a 'Pinout" for you from the 2003 and the 2004 to see if they are different.

Also, is your car a 2003 or a 2003.5? If it's a 2003.0, it will not be PnP because they have different BCM's, and different ECU's, etc. But you can probably get it to work with some wiring.

Which brings another question, why did you do this, and do you need to? What's the reasoning here?

 

Ok dude, so based on the (sometimes inaccurate) FSM's (link below), the 03 and 04 clusters are different in how they wired the VDC light.

here are the plugs on the back of the cluster, with the pin designation.
This is the SAME for 2003/2004




Here's the 2003 VDC wiring. Looks like Pin #34 is the signal for triggering the VDC light ON. Most likely providing a ground signal, which lets power flow and light the bulb.




Here's the 2004 VDC wiring. Looks like Pin #34 still looks like it triggers electrical flow, but Pin #46 is now looking like the ground path.




I haven't found the more specific wiring that I would need to determine exactly how the above wiring works, and which Pin's are actually doing which functions. The Gauge cluster section is very vague about the indicator lamps.
It might be in the FSM somewhere but I just haven't located it.

Also, here is a quick picture of how the CAN/Data system is linked into, and controlling pretty much everything through the multiple monitors in the car. A difference in one of these systems, mainly the VDC controller, could create a problem with compatibility of the gauge cluster also.

 

Thanks a lot for that info. The cluster is from an 04 with some options. My car is an 2003.0. I replaced my cluster because a while back I damaged the plastic cover on ny oem cluster and decided to run no cover. One time while wiping down my interior I touched the gauges accidentally and my rpms and gas gauge were never the same. So my vcd still works though when the switch is engaged right? Another issue i'm having thats even more annoying is the airbag light flashing. I tried to reset it and it still wont go away. That was there before I changed the cluster though

 

Well the airbag thing would be another issue obviously. If you didn't do any work on the car before it started flashing (front bumper removal, seat removal, etc), then it's likely an active fault that needs to be read to tell you what is at fault. there is, I think, a way to do this manuall without going to the dealer, search for that and post results. I've actually got to check mine as well in the near future.

If it happened after you had seats out, etc, then you should be able to simply disconnect your battery overnight, or, to be safe, for a day/weekend, that will reset everything. If the light comes back something is actually at fault and follow the above.

As for the VDC working/not working, I couldn't say, but I would guess it is. there's really only one good cheap way to check

 

Well the airbag thing came on when I got my steerint wheel reuphulstered. I did the reset myself and it went away. Months later I replaced the piece under the dash where the driver side air vent is . Near the steering column and thats when it came back and was unable to turn it off with the reset procedure. I had a shop plug in the computer yesterday and the guy said he was unable to shut it off. I did a burn out with the vcd off. Seems to be working fine lol
