I Suspect one of my height sensors has lost calibration/ no longer calibrated correctly. How to check and adjust? using the Launch diagnosis tool.
Anybody have good threads to link or can confidently explain the way the system calibrates which heights/measurements and data i need? or how to perform the action?
Back story: My pump broke due to a pressure sensor issue and the front right actuator had to be replaced due to a snapped bleed nipple (which i missed when buying the car) parts were replaced and the system is working except for the fact that the front left is about 5-6cm lower than the front right (now the front left tire is rubbing while driving).
Since the repair took a while the car was left standing on the front bump stops. The AHC fuses were pulled before the repair but the ignition has been on/ the car had to be moved at points.
Measurements as it stands in N from ground to top of wheel arch:
FL 83cm FR 88cm RL 93cm RR 92cm

I have gone through and searched on the forum but most seem to be about sensor lift and newer vehicles.
Would like to try a few more things before i give up and bring it to the Toyota dealer from a time vs money perpective
Additional information:
-vehicle has done 388 000km, fluid flushes on the system have been done by previous owners.
-No records of part replacements - before the system broke, (supposely toyota checked the functionality of the system before purchase)
-There might be wear and tear on the globes since the suspension is pretty firm/harsh even after the repair and flush.
-Front height sensor links (left and right) broke due to seized ball joints when lifting the car. Replaced with new parts.
-Moved the linkage up and down the sensor arms - Made a temporary difference until the vehicle was driven.
-Performed a test to see if the system lost pressure (similar to air suspension)
measurements at N when Starting
FL 83cm FR 88cm RL 93cm RR 92cm
Had the vehicle in H for 72H, Measurements were:
Start FL 90 FR 92.5 RL 98.5 RR 95.5
After 24H FL 89 FR 92.5 RL 98 RR 97
After 72h FL 87.5 FR 92 RL 98 RR 98
When dropped to N After the test.
FL 84 FR 87 RL 90 RR 91 (did not have time to drive the vehicle yet but expecting the same as with the adjustment test above)
