Only Happens in 4 Low

[siringo]

Got call from Nissan Australia today.

It's official, the crappy drivability problem is "normal operation". There is no known fix by Nissan or third party (that I was told about).

It never bothered me before I knew there wasn't and isn't going to be a fix, because it's not a problem you come across in daily driving, but now I know there's no fix and no help from Nissan, I feel cheated and ignored.

Imagine buying a car that can't be driven in one of its gears and the manufacturer says "no, that's how it's supposed to work".

Another design flaw? But what on earth could it be? Chances are it's a programming issue, if the TCM is replaced by the unit available from Wholesale Automatics it might go away?

You can reprogram them but its not an update. I don't think a chip will help cause they just resend the info but with a lower reading causing the pressure on the rail to be raised. What's your boost doing at the time?

That's one of the annoying things Tony, the service manager at the Nissan place I went to, to look at this problem for me, told me they'd had quite a few of these and that they had never been able to fix the problem. Now that's a smal Nissan/Ford dealer in a small Victorian country town, saying they had had quite a few with this problem.

So I wonder how many across Australia, New Zealand and so on would have this problem.

The service guy also said the problem wasn't known of in the next release of the vehicle, so there's obviously a fix for the problem, but Nissan have decided not to worry about formally releasing the fix.

I don't know Hatchy, but I can log it with Torque and find out.

It is a pain in the arse iv been doing alot of hunting in the wet lately u cant use high range because it stalls when u hit the mud and 3rd gear low range you are reving the shit out of it to sit on 25km per hour and it is impossible to use 4low because surging

 

[siringo]

That's spot on, that's what I find. 3low is too low and 5low is just a little too high. It's not intolerable, but the thing should just work.

I've emailed DP Chip (Berima Diesel) to see if they know anything about this problem.

Thanks siringo. Keep us posted

Spoke with Andrew from Berima Diesel (DP Chip) this morning, he hasn't heard of this problem and wasn't able to shine any light on it all.

Nice guy, know his stuff.

Well after much reading I found a tsb for you king cab lads. Surging issue can be caused by a faulty wiring harness. Will upload more detailed explanation for yas on Tuesday

Ok, the bird revealed himself thanks Hatchy, it's great to have someone that can hunt for this stuff that dealers normally won't help us with.

Well this is great news.

What I don't understand is how the dealer I visited and how Nissan HQ couldn't come up with this? Not knowing what's involved I can only guess it's like searching Google for something, it can take many different queries, each query worded slightly differently until you find what you're looking for.

So I'm guessing if we get the info that identifies the TSB (Is that for technical service bulletin??) we can then take that info in hand to a Nissan service centre and ask to have the problem looked at.

Thanks Hatchy, I really appreciate your efforts.

 

[Hatchy]

It's on the niscom system for dealers and depending how anal they are prolly over looked it. Now normally surging is in 2 wheel drive but I think it will cause it in 4 low also.

 

[siringo]

Yep, I'm really keen to see what we find out from this. Thanks once again for your work Hatchy.

 

[camo.b]

Same problem here too.are you blokes still under warranty? I've got a december 08 built kc.love to sort this issue

 

[siringo]

Yep, I'm still under warranty.

 

[longy509]

Great news Hatchy would be great to get this fixed

 

[siringo]

Hatchy, any updates mate???????????

I'm not sure about this, I have just stumbled on this thread. But I remember reading on this forum that their was a guy that could reprogram the ECU to run the same as if it was chipped. I remember he was saying he could do the mod for a quarter of the price of buying a chip but give the same performance. Like I said not sure. But if you can find him maybe the re programming he dose could fix the problem. It was in one of the chip threads. Hope this helps somehow?

Cheers.

 

[Hatchy]

Sorry I've been away for so long guys just been hectic. I've got the tsb on my old phone ill email it tomorrow and post it up here when I do!! Sorry again lads

 

[siringo]

Hatchy, that's OK, I for one am very appreciative of anything. Thanks for your help.
