LR3 Suspension Faults w/troubleshooting updates
#21
Alright then....my theory is blown. I don't understand why you would buy a GAP tool without paying to unlock it. That's like buying half a tool...and I didn't even know you could do that! Maybe that's a new thing.
Anyway....I digress. There is a "guided calibration" now, but I haven't used it to be honest. I have only calibrated the "old fashioned way" using measurements and live values. I'm not familiar with the app sensor calibration. I will go take a look.

update*
Gap tool used to deflate and re- enable eas. Clear codes. Front valve block and air strut replaced. No codes have returned. This repair may have paid for the gap tool. I appreciate the recommendation, thanks again!

Alright, my GAP tool arrived. I have 3 EAS codes that popped. The first one, I believe to be the culprit. The following two I believe were cause by my troubleshooting method(s).
C1A13-64 (6C) Pressure does not decrease when venting gallery - algorithm based failure - signal plausibility failure
C1A27-12
C1A27-14
I have cleared the codes & started her up. Compressor came right on. Unable to raise the height. Compressor shutoff after about 2-3 minutes of runtime. No new faults present.
I'm really scratching my head here.

I ordered the compressor dryer valve and solenoid rebuild kit from 4x4 air seals. Last night, I changed out the dessicant (it was pretty wet) and all the o-rings. Re-installed everything on the car (remember, this is an AMK compressor). The vehicle doesn't want to raise or lower using the height selector switch. I had trouble getting the compressor to kick on, but, using the GAP tool, I was eventually able to get her to kick on and raise a bit. Then, the infamous C1A13-64 code returned.
I pulled the exhaust valve solenoid. It appears to have just 2 power inputs. I applied 12v: nothing happened. Anyone know a solid way of testing these?
I'm still not clear or certain as to what the issue here is. Here are my next steps:
1. Determine how to test the Exhaust Valve Solenoid & verify functionality
2. If that doesn't show a failure, use the GAP tool to recalibrate the EAS

Update:
Using the GAP tool, I'm able to control each corner of the suspension without issue. I am able to raise and lower. I can hear the exhaust valve functioning. Due to this symptomatic data point, I don't believe the physical exhaust valve is the issue.
I attempted to complete the guided EAS calibration yesterday, but during this, could not get the vehicle corners to lower. I'm uncertain why. I'll reach out to GAP.
