Hi - Looking for some help with diagnosing an air suspension problem. Some time ago, I parked the car @ Target and put suspension to the max height to ensure I wouldn't scrape the bottom on those parking blocks.
When I got back in the car, I started driving off and set the suspension to "normal" height. Ever since this, the car has not been behaving correctly and I will get errors if I try to adjust the suspension. As my typical trip to Tesla service turns into a game of replace a bunch of parts, and get a large bill, I wanted to do some diagnosing on my end first.
I got ahold of Toolbox 3 recently and took a look around. Running the solenoid check seemed to indicate all was well. (Though I'm not really sure if it actually tested anything....) The pressure readings seemed to be in alignment with the height of each corner. (e.g. front is sitting higher and had higher pressure which seems to correlate)
With the help of a local mobile tech, we used the Tesla tool to try and recalibrate the ride height calibrations. When entering the measured values, the processed FAILED with a statement that the Measured Height (TAS) vs. Measured Height (Technician) were not within tolerance. Of course nowhere is a tolerance specified... *sigh*
TAS readings were:
- FL : 260
- FR: 268
- RL : 193
- LR : 196
(NOTE: These make sense as the car *IS* sitting higher in the front than the rear right now and our measurements were similar)
Oddly, when going to the Read Ride Height Calibration Action in Toolbox 3 we get an error:
Exception "KeyError" args : "TAS_HEIGHT_SENSOR_OFFSET_FL"
This *feels like* it is having trouble reading a value from this sensor.
There is also an active alert stating: "TAS_a210_outOfRangeCalibration" - Received ride height sensor calibration values are outside of allowable range.
Two questions:
- Anyone have this situation before? If so, what was root cause / how was this resolved.
- Is there any tool that I can use to attempt to manually control the solenoids to individual lower corners *AND/OR* view ride height sensor data in real-time? Toolbox 3 doesn't seem to have a live data viewer. It does have a "deflate" option; however, it looks like it will just dump all the air and I really just want to try and incrementally lower the corner. If someone has CAN commands for this, that would be super helpful as well. Perhaps there is something to specify a target solenoid pressure?
