The problem is the 108 fault. Car runs all day long without any weight in the car. Put 50% of the load and the car gets a 108 fault coming into the bottom floor. Load weighing is adjusted properly. If I tune the load weighing down to read less than 50% (43% to be exact). The car will make the bottom floor no problem. But then it gets a 108 fault trying to leave the floor. The other faults listed were symptomatic of the 108 fault. 108 is a motor tachometer fault but car runs flawlessly empty car top to bottom and anywhere in between. Also, I have never seen channel faults on the ADON board so the tach has been ruled out. Load weighing board and drive swapped with no change. Seems like the pattern is hitting a torque or current limit coming into the floor. But why only at the bottom floor with a balanced car? Doesn't make a lot of sense. Aqua dog. Any ideas?
