Nats Error

[smoothV35]

Hi guys, I have done a search but nothing turned up in relation to NATS.

A little bit of background info first. My car is a 2002 350GT-8, it has the factory immobiliser deactivated (the LED that has a 'Security' sticker under it is off) but a factory fitted alarm that is still working (I set it off to test it). It also has an Autowatch 3 point immobiliser fitted that has a little LED indicator light next to the VDC button.

I was told that in order to start the car, I have to turn the key to the 'ON' position, at which point the Autowatch LED will light up continously, then when it turns off, I will be able to start the car. But the problem I've been having is the car basically has a mind of its own, sometimes it starts, sometimes it takes 2 or 3 attempts.

So I took it to a Nissan workshop and got them to hook up the Consult-II tool and search the whole system for error codes. The only thing that came up was 'NATS error', which I know refers to the security system but I'm not sure what exactly.

Are there any experts out there that can shed some light on this annoying problem? Thanks in advance

you are in brissy correct?

I know what is causiing it I just need to verify it.

So don't leave me in suspense, what do you have to do to verify it?

I would say he needs to check the car for you...

Thanks for that Captain Obvious.

And I bet he wants to charge me money just to do a simple 5 minute fix instead of just telling me what it is so i can fix it myself.

When I discovered how to get the oxidisation off of the windows, I shared that info with everyone, not a problem.

Isn't this forum about being part of a group that supports each other and shares the same interests, not a place for opportunists trying to make money anyway they can?

Hey mate calm down, I don't think he was trying to be a smart as$

Chris is good with these types of things and has a lot of experience and I'm sure will be more than happy to help you out anytime, just send him a PM and have a chat with him

[Stephen Thorpe]

What the hell was that for? There is no need to be rude and call me names...

Perhaps some things are easier to check if you know how and obviously you don't, so please pull your head in and don't call me names.

Also, maybe he wasn't planning to charge you, I know if it was me and it only took a bit of his time, he would bend over backwards to help.

As for the oxidisation discovery, isn't that pretty easy to explain on here and perhaps fault finding a 2002 Factory immobiliser is a bit harder to do whilst online.

Also, I know what this forum is for and it isn't for openly having a go. If you are upset then please keep it to yourself, or complain to a moderator. As for opportunitists making money, it is your car, your money and your choice.

[Stephen Thorpe]

Thanks Pulp and no I wasn't...

Hi Pulp, thanks for trying to smooth the situation over, but Stephen knows he is being a smart as$, thats the second time he has chimed in with a useless comment to try and make me look stupid.

Chris is no doubt good, but at the end of the day he is a business man and will try and make a buck, so I should expect that.

But you can be sure that any new information I find out about these cars will be posted loud and proud for all to see Have a good one

[Stephen Thorpe]

Just for the record, there was absolutely NO intention to be a SMART ARSE and I take exception to that.

As for trying to make you look stupid, again that wasn't my intention, so my apologies.

However, if that is what you think please yourself.

As for Chris, I think if you think he is out just to make money, then I think you have that wrong.

So you think he wouldn't charge me? Then why come on here and say 'I know what the problem is..' etc. but not tell me?

And as for me being rude, I think you earned it. Two times you replied in my posts and both times it was with a useless comment. My tip to you is don't post unless you have something worthwhile to add or a question.

Anyway, we have both had our say, lets agree to disagree and get on with it.

Thanks for the apology Stephen, I believe you mean it and if what you say is true, then I must be reading your replies in the wrong light. Thats the trouble with reading and not hearing what someone says.

So I apologise for my remarks to you then, have a good one.

[Stephen Thorpe]

Remember no matter what you might think, being rude to someone doesn't help the situation.

If you think my comments are wrong and I have earned it, ask me about it in a PM, because I think you will have me wrong.

As for Chris, I presume he is a busy man, like all of us and perhaps he would prefer to work over the phone at the very least... I know of a very different side to him and he has never got money out of me... so far.

Have you tried to call him... his number is on all of his posts?

agree to disagree

[Chris Rogers]

I would say he needs to check the car for you...

exactly.

if it was a car that I did during compliance I could tell you over the net via PM. I dare say its not.

I really need to see the car so I can verify : alarm model, installation, put a face to a name

and no if its a 5 min fix (which it sounds that way.) I'm NOT going to charge you.

stephen has met me. I'm not an opportunist- I do work on A LOT of these cars daily and have a decent understanding of them.

busy- me . never (say he that just finished a sedan and has 4 more cars waiting- none of which are on this forum.)

at the very least give me a call during the day- I *may* be able to sort it over the phone.

tell me who did the compliance on the car as well . sticker is inside the passenger door.

considering that the car has 4 major networks in it its not something that I would even attempt unless you had a background in autoelectrics and electronics.

I think you'll find that it only has 2 major networks, called CAN H and CAN L. One being high speed for the important things like ABS etc. and the other is low speed for power windows etc. And these two networks are linked for redundancy, allowing bcm's to be able to continue communicating if a section of the comms bus is broken.

[Chris Rogers]

correct. there is also one for the AC unit and one for the navi/cluster. they are separate.

sounds like you have a service manual so you should be able to fix your problem

I thought it was a single CAN network with 2 communication lines (CAN H line and CAN L line)? Not 2 networks. Then there is the K line for all the OBDII diagnostics stuff, navi/TV/display bus and probably A/C bus.

I'm with smoothV35, unless we share information we will never learn.

I know what you mean mate, just depends how you look at it. For example, the Internet is one network, however it obviously has countless networks within it aswell.

Even though CAN H and CAN L are physically linked, logically they are separate, so they can be classed as their own type of network, thats what I was alluding to

Discussion is good though, we can learn off each other, and my plan is to totally crack open the mystery of how this cars internals work so we can do what we want to it.
