R32 GTR Air-con

Hi Lads,

Cannot find answer after numerous searches. I live in a hot climate, and as a result the air-con sometimes takes a while to work. I set my unit to 20 degrees and only the foot vents work until the car cools down enough, then the top (dash) vents open. Must switch once the difference between the set value and the AMB value is small enough (maybe 8 or 9 degrees).

What really annoys me though, is that I cannot manually turn the top vents open until the cabin cools enough to automatically switch.

Is this normal? Can I override this?

Thanks, regards

The climate control has a feature that isn't documented in the R32 owner's manual.

With the fan on, temperature set at 18 (the lowest it will go), press and hold the temperature

down button for a couple of seconds. The climate control will show "FC", the air conditioning

will come on in re-circulated mode. This must be a fast cool, as it sets the optimum setting for

cooling the car quickly. The re-circulation mode can be turned off.

There is a "FH" mode also with the temperature set at 32 (the highest temperature). Press and

hold the temperature up button to enter the FH (fast heat?) mode.

Lads - thanks for the comments.

I know about the mode button - it switches to manual but still does not change vents.

I know and use the FC mode quite regularly - we must have downloaded the same skyline 'book!'

I ran a diagnostic check a few weeks ago, and it came up with a sunload error (common, ignored) and a water termerature sensor error. I do not think this has anything to do with the vents, though, as the AC is bloody cold when its working.

It just takes a little time to switch vents over, depending on the inside car temp.

Thanks for the comments lads.

He had the car for a few days, Changed from old gas to new, cylender was damaged so he had to degas it, replace and regas it again. new control unit, from memory around 300. the guy I use is really really good. I always take any of my cars to him without a worry

Who is this guy? How much for the gas switch?

Cheers,

      FWIW a lot of the local owners that do a big build tend to have cars that are perpetually broken.

      R34 GTT Battery Relocation To Trunk

      I just got this system but haven’t installed yet I got a Moroso sealed box (defect reasons) which will be set up same as their pic The quality is high grade, the correspondence I had with the owner (former head designer for Rockford Fosgate) was unbelievable, guiding me with what I needed. Even told me not to buy some things as it could be sorted in a different way at his loss. Just a bit of a bite with the exchange rate and don’t purchase gear in 1 hit that goes over $1,000 au, lol I forgot!

      Rv37 400r questions

      By elir32 · Posted

      Thanks mate for that reply. Very helpful.    it’s a 2022 400R so would most likely lose those features as you say.     I did a quick compare of a rv37 nav and heading for sale in Japan to q50 model. I’ll pop pics below. Seems  Japan spec head into top, nav unit second below it   below pic Q50 aud delivered     differences seem to be Aus delivered has a different plug top left hand side of head unit- not sure what and where it goes.   and nav unit Japanese tv37 had an extra plug put    Again I’m really not sure what each of these differences mean!       the actual plugs on a v37 and q50 screens look identical on both screens… pics below for comparing. (One screen was is a us delivered one) but should be same gps signals etc as Australia.    If it were as simple as swapping a nav unit from q50 aud delivered im interested -just want to figure out what the missing plug is for before spending big $ on a second hand part for it to not work, and I guess with the head unit, if the band expander does the job (I got a 20mHz so should get the range I’m after) so should narrow my issue down to nav unit only.  I’d love to know what the extra cable on rv37 does and if I eliminate that part what it’ll do to the setup,    and also, if I can figure out what that head unit plug difference is, what does that cable do and where does it got can it be altered or re-plugged?! Excuse my ignorance what is ACP/AA, what does that stand for? (Apple car play? Android air play)? so If I swapped head units to save using a band expander, I’d likely lose those better features to have an oem Unit operational. Better to use a band expander and retain AirPlay options and newer version of head unit     provably best to band expand it, and focus on the nav unit. th isn’t  a big deal/ would be cool to have it working  from what I can tel we use a PAL Signal and Japan uses a NTSC signal  I don’t know if there’s a co better or if the screen only reads NTSC, or if it’s the tv module that needs replacing… no big deal don’t need it but more of a curiosity thing on that!   Thanks for the info re tyre sensors, helpful and great to know.  I was reading the online manual off Japan website and it seemed to make it sound more confusing than it is  I guess a rim replacement would require the sensors to be moved to a new rim to carry that option over?!     Thanks for the info regarding diagnostic mode. I appreciate your help mate. Trying to brainstorm here to find a solution to get as much gadgets as I can working! I plan to get my local Nissan tech to have a look too who used to be at an Infiniti dealer back in the day to see if any thing they have or idea can find a soliton. But hoping anyone here has gone down the same route to make life easier!!   i guess identifying the cable/plug differences and what they do would be a great way of finding out if the units are transferable    thanks again

      Rv37 400r questions

      No idea about the remote start part. If the V37 nav is anything like other Nissan JDM vehicles, you can't get the factory Japanese nav working in australia, a card from a different car almost certainly won't work, those cards are usually matched to the serial number of the DCU.  You could be possibly swap out the components from a AuDM Q50 to get it working, but if this is a new model (2021+) 400R, then you will lose the newer features like ACP/AA.  That said, if you have ACP/AA, just use google maps.. I assume a band expander would be required to get the local radio stations, but don't forget the Japanese FM band is narrower than ours, so you still might not be able to receive all Australian stations. I can't see any reason the tyre pressure sensors won't work here, there is the sensor unit inside the rim and the receiver nearby in the wheel well.  I have never had to change the batteries on my 2015 Q50, so I assume they last quite a while.  A straight battery change shouldn't need them to be re-registered as they are the same unit, that should only be required if you replace a sensor with a new one.   Word of warning, if you ever go into the 'secret' diagnostics mode on the main screen, DO NOT EVER do a 'reset' in this menu, it will erase all of your model specific data in the DCU and you will need a trip to a dealer to re-program it all, which would be particularly painful being an import.  This applies to the AuDM Q50 too.
