I had a Scan-gauge 2 in my 2012 Highlander that was a base model. It offered a lot more options then the Highlander had. I kept the scan-gauge when I traded it in because the dealer said they didn’t intend to keep it in the car anyway. After I got my 2020, I never felt the need to install it because of all the info that’s important to me is already available from the instrument cluster now.

 

As a techie type person, I'm a Medical Physicist treating cancer patients, more data is better, so this little tool satisfies my OCD. It may come in handy some day,probably not. But I found a place to put it on my dash.

 

That's the exact spot I had planned to put mine LOL. It's 18 years old and just recently had the software upgraded on it. It involved replacing the entire circuit board inside...weird.

Can you describe how you routed the cable and post a pic. Thanks.

Btw, what's the color code for the screen?

 

The cable is routed by the door, the color code is light blue. The cable is double backed...next to the door, then hidden in the door.

My OCD kicked into overdrive after reading this post. I've wanted to monitor Transmission temp and Oil temp since day 1. Since I own a Hybrid I'll have to do a bit of research and call the ScanGuage folks to determine if they can deliver those parameters for a Hybrid with the 2.5 L 4 cylinder.

 

I have it mounted behind the steering wheel. This is how I had it on my last car for over 10 years .

The cable is zip tied and run up behind the steering column and through the apron.

I have AOD setup in addition to those mentioned. It shows Alternator Output Duty cycle as a percentage. Basically how hard the alternator is working at any given time. It’s a little unnerving at first seeing the voltage drop to 12.1v while driving and AOD at 0. But always kicks back up when needed.

If you plan on doing DIY tranny fluid replacement like me, that Trans Fluid temp will be invaluable , since a specific fluid temp threshold is required to set the fluid level.

One thing I’ve noticed is the OBDII plug is impossible to get off. I have to drop the undercover and flick the white tabs to release. You wouldn’t need to do this often but it’s something to consider if the car ever needs to go into the shop for scanning or software updates. You don’t want gorilla forearm techs yanking on that thing. Maybe I’ll grind the tabs a little next time.

On my last car it saved me twice , once from a failing battery and another time a corroded Alternator ground that broke loose. Got things fixed up before getting stranded.
Overall it’s well worth the investment.

 

I used a splitter when I installed mine. Leaves nothing sticking out and leaves the port open if scanning is needed.

 

I've always thought of putting this in my car but there are alternatives through the usage of apps and OBD2 dongles. My issue is when I have used it this way and I put up everything that I want, I never look at it.

 

Scangauge gives you live data all the time as you drive. Those dongles/OBDII apps obviously only work while the app is open , what if you want to run some other app while you drive? They’re more for troubleshooting after the fact, a standalone system will help prevent the problem in the first place. But you’re right it’s for a certain type of driver. Using it is no different than checking your surroundings once in a while, we all know some drivers don’t even do that.

So, what exactly did you do here?

Pulled panel, notched the top so the wire can go through and put back trim

 

I'm currently trying to program my Ultragauge, using their method, to display transmission temp for our 2018. I know I'm in the wrong forum, but may I ask you which codes you're using on your Scangauge?

I'm hoping they can translate over to the UG and give us trans temp functionality for a long road trip we have coming up with a 4'x8' enclosed trailer in tow.

 

This worked for my 2015

 

Not sure about the Corolla but this is the one in my Camry.
