As promised, here is my write up on a special firmware version of the ScanGauge 2. I'll let you visit their website and all the information available there, rather than repeating it here. It's a nifty device all on its own and not very expensive. You can take a look for yourself at http://www.scangauge.com/products/scangaugeii/
I originally contacted them to find out if their X-Gauge feature could access any of the air suspension module parameters. I was having a lot of trouble with my air suspension and had no way of getting real-time information from the module. They had never done it before but were game to try. After some back-and-forth (and assistance of my local mechanics Scanner) they were able to produce a unit that believed could monitor several key parameters that are available on the CANBUS.
Once they shipped it to me, we further tweaked it back-and-forth by email. A huge shout out to James DeLong, Development Engineer at ScanGauge for his help and R&D on it.
In real-time I can now monitor:
- System pressure SPR (psi)
- Compressor temperature CPT (degrees C or F)
- Compressor run CRN (ON/OFF)
- Ride height sensors for all four wheels LFH, RFH, LRH, RRH (inches or mm)
In normal operation, it's just neat information to be aware of. It's good to become familiar with how the system behaves and what the expected readings should be. I've also made note of them so I know what they were when the system was working right.
For example: If I am concerned that an air bag might be leaking, I can park the Jeep in the driveway and temporarily disable the air suspension (holding up-and-down ride height buttons for 10 seconds). I take note of the ride height sensor data and leave the vehicle overnight. After enough time has passed I get back in the vehicle, start it, and verify to see what the changes have been in the ride height. The temporary disabling of the air suspension remains in memory until you turn it back on or begin to drive the vehicle. I monitor my ride height in millimeters, but it can equally be displayed in inches instead.
I was having a lot of trouble with the air compressor running excessively. Trying to listen for it though was difficult because there are lots of other things that cycle under the hood. Now I can see if an "on or off" command is being sent to the compressor and by being able to monitor the compressor temperature, I can tell if it's running more than it should.
As a sidenote, when I was pulling the camper trailer I wanted to be able to see the Transmission Fluid Temperature continuously, without having to flip through the EVIC all the time. Sent a quick email to James and after several attempts we got the right codes into the ScanGauge unit to monitor TFT as well. Originally he gave me it in degrees Fahrenheit and I was able to change it to Celsius, since I live in Canada!
There you have it! If you're interested in one as well, contact James DeLong with the JEEP QUADRALIFT Code and he'll know what you're looking for.
Here are some screenshots from the gauge.
