Hi all

Can anyone confirm if the M35 Stagea (and the V35 Skyline for that matter) have CAN Bus signal on the OBD2 interface?

I have read this: CAN Protocol Pins : If pins 5, 6, 14 and 16 are populated, the vehicle supports CAN.

On the OBD2 connector, 5 = GND, 16 = PWR, 6 & 14 are Data (CAN).

My connector has all these except 14 is missing. There is a wire (green/yellow with pink band) turned back in the harness and connected to a different coloured wire. It looks decidedly aftermarket (unsure of its use) and I reckon it would have come from position 14 on the connector.

Can anyone drop their OBD2 connector out and confirm they have a wire in pin 14, and report on the colour?

If you want to compare all colours, mine are:

1. Yellow/black

2. Empty

3. Red

4. Black (with white dots?)

5. As above

6. Light blue

7. Purple with pink band

8. Green/yellow with pink band

9. White/green with pink band

10. Empty

11. Empty

12. Yellow with pink band

13. Brown/yellow with pink band

14. Empty but probably should have Green/yellow with pink band

15. Empty

16. Red/white with pink band

Now, why do I want to know?

Anyone without cruise control watch this spot. I'll be posting more info about a drive-by-wire cruise control when I've nailed down some answers (like this one).

It can be connected with wires to the speed signal, tacho, brake switch (& clutch if you have a manual) like most D-B-W systems. BUT, to make install easier, it can just have have 2 wires connected to the cars CAN Bus, if it is so equipped, and you don't need the other signal wires. How easy is that!

Oh, and 2 other really good things, it plugs into the connector on the accelerator pedal and is compatible with the steering wheel controls.

I'll fill in more details soon, but if I get enough interest you could have "state of the art" cruise with factory controls installed at your place in an afternoon for $600 or less.

Anyone want to help with wire colours and locations now?

Cheers, Leon.

The M35 is obd2 but not the compliant version. The 350z is, and the VQ35 version of the V35 should be... What is it you would like to know?

If running an aftermarket ECU (such as Link/Haltech/Motec etc.), will they be able to interface with the V35/350Z CANBUS system, or do you need to run the factory ECU to control that with a piggyback?

Just trying to find out how easy it is to run the R34 GTR box behind a VQ motor for manual action (and AWD). Both V35 and M35...

I know you have a fair bit of experience with this Scotty, so just picking your brain (and anyone else who has done something similar....)

V35, fairly easily with the 3.5 using a plugin (platinum pro), hard with the 3L and 2.5. I think the Link would be the better option, and much cheaper than the Motec.

M35, almost impossible with the 2.5det at the moment, no-one has managed to fit a full standalone on the det afaik let alone a manual box.

I would be going with the R33 gtr box personally, as they are 1/4 the price. You can buy an adapter plate from for VQ to RB conversions for around $1k US. Lot's of custom work required, and the V35 manual interior parts required are hard to come by.

3 year old posts don't warrant responses. :P

:) I see no one actually answered my original question (had to figure it out myself by experimentation), so why would anyone bother clarifying a throw away statement like that...

It's a shame we can't get the cruise to operate through the can network, I suspect the cruise setups we are using at the moment cause occasional differences in resistance, triggering limp mode for the throttle circuit. I have had to disconnect one of yours Chris, and I think mine is still playing up too after already swapping the throttle and pedal assys. I will be dropping the adapter loom for the pedal next, to see if the occasional limp mode stops occurring.

I'm after a OBD2 blue tooth device that works..........

I bought one of these "http://www.ebay.com.au/itm/ELM327-Interface-V1-5-Bluetooth-OBD-II-OBD2-Auto-Car-Diagnostic-Scan-Tool-AU-/251319157864?pt=AU_Car_Parts_Accessories&hash=item3a83ca0468" only to find its not compatible :(

found out after I got it that it only supports Nissan sunny and x-trail..............FFS.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
