Scangauge question: AT Temp?

[Martinjmpr]

I've seen conflicting reports on whether the Scangauge II can be made to show AT temp. Some say yes, some say "maybe." Anyone know for sure?

I'm currently running an Ultragauge but it does not show AT temp on the 3rd gens and according to the Ultragauge website, there are no plans to upgrade it to do so.

I've recently been thinking of adding an AT temp gauge to my '99 SR5 but a scangauge would probably be less expensive and I can always throw the Ultragauge into my DD 97 Mazda which has a manual tranny anyway.

A smudge more research and you would find your answer.

The SGII will show ATF temperature on 99-newer 4Runners. It will NOT show an ATF temp for 96-98's.

The 96-98's do not have the same physical trans temp sender as the newer ones. Hence, the OBDII does not read a specific temperature during operation, it simply sets the "idiot" light off when the trans gets over temp. Which is probably north of 300 degrees.

My sgII reads my '99 tranny temp just fine.

So to answer Martinjmpr's question, YES, your '99 will show ATF temps.

This, my buddies SGII showed my 2000's sr5's AT temps after my bm70268 cooler.

It would have before as well, just to be clear.

Yes, I know. Just wanted to too see how warm it got in traffic.

What's average temps for everyone? Mine rarely tops 160.

here's some of the custom codes we've come up with for the Scangauge II...

Transmission Temperature #1
TXD: 686AF101B4
RXF: 044105B40000
RXD: 2808
MTH: 00090005FFD8
NAME: TFT
Notes: n/a, displays in degrees F

Air : Fuel Ratio #2
TXD: 686AF10124
RXF: 04410524
RXD: 2808
MTH: 05B900800000
NAME: A/F
Notes: Ratio
1150 is Rich/ 1775 is LEAN
**My Runner stays around 1453 to 1465 most of the time now with this code



Altitude Gauge (Feet) #4
TXD: 686AF10124
RXF: 044105240000
RXD: 2808
MTH: FEEE00016B08
NAM: Alt
This one doesn't work correctly yet

Im pretty sure thats the same code we used on my buddies SGII for the Trans Temp in my 4runner.

He also has some codes for engine HP and Tq. It says his 3.5L Isuzu Trooper makes like 230hp

Can adapt the newer sender to the 96-98 runners?

No, because your ECU still doesn't report trans fluid temp.

 

[montana_jeepn]

Darn. Thanks for the reply. Autometer it is then.

How do you set the SG2 to read the transmission temperature?

Which buttons do you press to see it? Sorry for the noob response, I just do not know how to set it.

And how do you set codes in it?

 

[Rock_Rat]

It's in the SGII manual that comes with it. Use the XGauge feature on page 25.

Sorry, another noob question. What do these numbers mean and how would you input them into the gauge?

I just told you in the previous post where the instructions are for entering the data in. I also included a PDF version of the manual. It's self-explanatory.

It's nothing more than hexadecimal, binary, code. Just found a pdf extract of the different byte parameters used. Enjoy
