I have a 2013 LX570 that just had 2 rear accumulator globes replaced. The system was properly bled and the Zero point calibration was done. I was not only having suspension concerns with the LX but now I have something electrical going on with the switches.
I should state that the previous owner had some electrical device interfaced with the AHC ECU, but that has now been removed. My issue now is that the system seems to not respond with switch input as if to say that some OTHER calibration or
"hand shake" has to be done. I have reset memory and performed several zero point cals. There are NO codes stored in the system and I have swapped out a switch assembly.
Any input to this would be appreciated.

 

Do u have a scanner to read input from the hydraulic sensors / switches? Need to see what the ECU is reading / receiving when the switches are being toggled.

 

I believe it has a switch issue because it failed the test outlined in the repair manual. All the readings when pressing the height button up or down indicated high resistance from the switch.
