2014 GU Fault Diagnosis

[Wildthing_507]

Hi,

I'm new here and may be missing something but I have had an engine light come on and stay on and all of the posts I've found so far relating to this say to "bridge terminals 1 and 8". Mine doesn't have terminals in the same locations as those?

As per attached photo

Top row
16,-,14,13,12,-,-,9
8,7,6,5,4,-,-,-
Bottom row

I'm sure it's just a later model thing but can anyone tell me what to bridge to check and clear codes?

Any advice would be much appreciated

i would suggest you need to have the codes read to find out why the light is coming on.
Im not sure i would risk and ECU by bridging pins

If you have a iphone - buy a ELM WIFI OBD2 sender on ebay for about $20 - then buy the OBD2 iphone app, and you can read the codes and clear them properly
Android phone the same, but buy the bluetooth adaptor

Or, you can go to Supercheap,a nd for $14 they will plug in their tool, read the codes, give you the report and clear them.

I'm sure some others may say you can bridge some of those pins, but really do you want to risk damaging your ECU for $14 at supercheap?

or if you want to buy the setup for a iphone check this out

or this for Android

I use the Dashcmd app on iphone
But i hear the Torque Pro app is good too - on both android and iphone

Thanks greatly. I knew I could get that done but I thought it was in the hundreds. You're right, for $14 I'm not going to risk it.

I went to supercheap and no fault code showed up. I've ordered the bluetooth reader from ebay, as it usually takes a week for delivery to Darwin, I guess its a job for Nissan at this stage . Bugger!

I don't want to drive around too much with the engine light on.

don't be surprised, if a $14 unit doesn't show up the faults either. I have a $3,000 snap on machine, and often it won't show up fault codes my mates $10,000 one does.

don't get me wrong cheap readers are a great tool for non-mechanics, and even as a mechanic it took me ages to fork out the $3,000. but a $14 tool is very limited in what it can do and see.

I have a cheap blue tooth one as well, and thought I would use it quite a bit due to being super easy, especially compared to setting up my Snap-On unit, but to be honest it is so limited I haven't bothered.

hopefully in years to come the price of quality diagnostic gear comes down in price!!

woudnt the patrol still be under warranty being 2014

[Wildthing_507]

Yeah but because I've blocked the egr valve I wanted to find out if it was something simple before I uninstall the blanking plate to take it to Nissan. The Blocked EGR valve made too much difference in power and economy to write it off and remove the plate without trying everything else first.

Logic says it would be to do with the egr but it's been blocked for weeks with no dramas and by the comments on the forums it seems that the engine goes into limp mode if there have been any problems, albeit rare, with the egr blocking. I don't want to uninstall it and find out it was a dodgy sensor somewhere completely unrelated or something like that.

Removing the plate will be the next step and it will need to be soon though.

I wouldn't buy the $14 unit if it just did the fault codes. After reviewing it, it has some other cool stuff that will hopefully be useful. If not, then $14 and $5 for the app down the drain. No big deal.

I was just hoping to get a diagnostic with the egr plate in place out of curiosity as much as anything. Looks like I'll be taking it out and booking the car in to Nissan. I know of people who have left the plate in and got warranty work done but I wouldn't risk it. I will leave it in for services but if they find a fault with anything even vaguely related to the egr they will blame the plate whether it's responsible or not.

Again, it's too awesome to drive with the plate in, more torque, smoother running with less surging, less turbo lag especially of the mark, economy. So If the plate is the culprit then so be it, it has to go, but only once I'm certain.

If you havent drilled a 10mm hole in your EGR plate
the ECU will keep throwing up the Check engine light

Just something the CRD's do
