Forgive my if you already know this. I'm forbidden to search.

I come from G20.net, someone just found how you check outside air temp, inside air temp, and intake air temp using your auto climate control. Turns out it works on Maximas too. I thought I'd tell you guys in case you didn't know.

1. Turn key to ON
2. Within 5 seconds, hold down OFF button on HVAC for 5 seconds
3. All elements in display will light up
4. Press ^ (HOT) key 4 times - I got code 51 here
5. Press DEFROST key

BEHOLD! Ambient air temperature! Oh yeah, I got 111*F!

You can then press DEFROST again to get inside air temp and a third time to get intake air temp. Pretty slick!

It doesn't work while driving, but it's better than nothing.

To get out of the diagnostic mode, press the AUTO key.

Boingo!!!!! Whatup Dude??? I'm a380driver on G20.net....when did you get rid of the G???

boingo82

I still have the G, she's healthy as ever! The Max is my husband's car. Have not seen you at Gnet for a while - sad news, Dom's stealth G died yesterday. Hope you are enjoying your Max.

Funny story, this morning (before he knew abt. the climate control trick) his friend was getting a ride and asked if the car could tell the outside air temp. My husband said something to the effect of "what do you think this is, a &%*ing Mercedes?" So he gets home and I told him he had to try this...so tomorrow he has something to show his friend after all.

what? i just push the AMB button to get the temp outside, are you talkin about something else???

G20Flyer

Good to hear u still got the G I miss mine alot ...she got wrecked when someone cut me off

I like my max better than a mercedes

I think the 99's have that built in into the climate control unit. Thanks for the info, I will try it tomorrow. BTW, I know something is definitely wrong with my unit....do you know what the codes mean or where can you find out? Thanks.

OH DAMN! Thanks for the info. I just tried it right now and it did it.....

so this means that the sensors are all in place and can be tapped into with another display perhaps

boingo82

Oh geez..I feel dumb (and my husband dumber). I almost never drive his car, and he never thought to try that button.

Sorry, I don't. Someone just posted this trick on G20.net, and I couldn't try it on my G because it's a '94 and there was no auto climate control back then. So we tried it on Mac's Maxima and found it worked. I don't know anything abt. the codes and such.

Glad it helped somebody!

Thats awesome! I wish we could find a way to wire it for 97 without having to do all that though!

I dont know why Nissan never had that to begin with in all of the climate control units starting in 1995. This feature comes in handy when you come in the car but it sucks that you cant check it while driving. Its cool nonetheless.

the 98 auto cc has everything to check the temp, but they never but the AMB button in. I cant understand why, but there are ppl who modified the CC and added the AMB. Nice find though.

*EDIT* It works while driving if you follow the directions then start the car. Of couse the regular CC functions dont work. But at the track this would be sweet.

Shift_Power

Awesome find. Just tried it, very cool. And will be useful at the track too.

Works on my 96 as well. One ? though. Can anyone actually get the intake sensor temp? When I push DEFROST the 3rd time I get 51, the error code not the temp. Anyone else?

Maximized Jiggs

iTrader: (1)

I dont get the intake sensor temperature either. Code 51 just like you.

DAVE Sz

iTrader: (2)

Never mind. Checked the FSM and 95-97 don't have the intake temp sensor reading available. Guess we're out of luck.

yeah, I was wondering. I guess I never studied the older 4th gens that closely. I just push the AMB button on auto climate control. However, this would be useful to get the intake temp and inside temp.

DAVE Sz

iTrader: (2)

I can get the ambient temperature and the inside temp. I just can't get the IAT sensor temp cause the we don't have the wiring or something. From what I read the AMB button doesn't solve this at all.

what i want to know is what the codes mean and you can do it with engine on and off

DAVE Sz

iTrader: (2)

It says what they mean in the latter part of what you posted. There's like 5 more pages after that, don't you have the rest?

maximus_pr

iTrader: (3)

but it don't tell what the codes mean

DAVE Sz

iTrader: (2)

Yes it does. It has the tables as you posted above. In those tables it has all the diagnostic errors and what they mean. It also says what every one of the steps means/does.

I wonder if the maxima has a trick like that to display battery voltage. That would be sweet if it did especially for the stereo guy's. Another thing I wonder if we can do is get a digital RPM readout instead of just the needle on the tach. On my VW I can hold down the trip reset button, turn the ignition to on position 2 times & on the third time start the car. Then my digital display in the dash under the gauges where the vehicle milage is displayed shows the exact rpm. eg. 5308rpm's. That would be nice to have on the max!!!

nostrixoxide

Well I think I have a good idea for a possible new Sticky regarding intakes. I just went out to the max & made sure I had the intake air tempature function "Which I do" & then took the car for a spin. I was able to drive the vehicle & toggle through AMB & IAT. The othside temp. was 80 degrees & my intake air temp. was flopping between 89 & 90 degrees. I also tried to see if once I left the diagnostic mode (turned on the A/C) to see if I was able to get back in the mode while driving. I had no luck with that. Maybe when i have alittle more time to play around with it I can figure out how. So were basically haulted at this time with putting it in diagnostic mode only once while the vehicle is running. Now back to the sticky idea!!!
Maybe we should create a log of outside air tempatures & intake air tempatures with several different intake designs (CAI, HAI, Hybred, Stock etc.) the see which intake is allowing the coolest air to enter the engine. We will need to post outside temp, intake temp., intake style/design (injen, stillen, JWT, etc.) and MPH for it to produce good statistics for us orgers to determine which intake produces the coolest airflow. Granted, I'm sure humidity will play a factor, but we are just looking for a example. Obviously if we want specific's we need alittle bit more of a controlled enviroment. But I think we can get a good idea by having a log to double check.

Good find. I wonder if it works on 5th gens...

Brudaddy

iTrader: (2)

I just went out and tried this on mine....it worked.
That is cool.
I have a 99 with the auto climate control and the AMB button, but now I can tell the inside temp and the intake temp.
Thanks for this....cool find.

Kevlo911

Cool, I just did this and it DOES WORK with the car on. In fact a waited about 10 sec after the car was on and it still worked, although when it gets to 41, the compressor turns on and when it gets to 51 it turns back off.

Brudaddy

iTrader: (2)

yeah, I don't really like that, because it is really hard on the compressor to keep turning on and off like that.
Neat nonetheless though.

MaxedOutOfCash

nice find...
when is someone going to find out how to change the *F to *C on our climate controls?

devilrba01

i have a 95 max and was just curious but when i cycle through the codes when i get to 5 so the one where you can check the outside inside temp if i press the fan button it comes up with 0c if i then press up it goes up to 3c by increments of 1 with no a/c indicator if i press down it dose the same just with the a/c indicator i could be wrong but i found testing with a thermometer that when set and saved on 0c the air is 5c colder and the low pressure pipe under the front is allot colder but on 3c ether way its warmer for normal operation than on 0c and the low pressure pipe on 3c not as cold also the auto climate seems to me more active when saved at 3c no a/c indicator what lead me to this was poor performance in my opinion and when car was stationary when i first checked mine read 3c a/c indicator on now i have it on 0c and performance has improved greatly so yeah just thought i would share if not already known btw i have a RHD version of climate control

pretty cool

same here, also when you are scrolling up with the ^heat button what other "tests " are the car performing, i can here the actuators moving and fans coming on?
