As you've got schrader valves, you can adjust the height manually, checking the sensor voltages & bit-counts throughout their range. Easier to debug the wiring that way, and you don't need to worry about reading faults or the ECU adjusting.Update time again.
All 4 air springs now replaced.
As mentioned previously, 1 old one popped (loud bang) on attempt to re-inflate via the schrader valves. the other 3 are all in what looks to be goodish condition, no perishing, so I will keep as spares in case of emergency.
Both rear height sensors rewired with new plug. One sensor RL, replaced.
Still getting signal incorrect errors on both.
Going to pump back via Schraders and see if the air holds for a week of sitting there.
Then if that is ok, back to what is causing the signal errors.
ON A SIDE NOTE: While I am there, I was cutting out the section of ABS/wheel speed sensor cable that got burnt by the exhaust (larger than standard exhaust) (was ok until it hit the bumpstops after the EAS failure). Stupidly I forgot to mark which sensor goes to which plug at the rear. Is it ok to swap them? I suspect they have to go to the correct plug. One has a white ring around the wire, not sure of the significance of that.
Your comments are appreciated.
Thanks
Nanocom will show the height sensor data in real time. Can't remember exactly, but I think in EAS-Unlock you need to click "read heights" after each adjustment on the air volume.
