I have had this problem twice and it must be a simple one but my bud from Kone has not revealed this to me. I have fixed many a sabotage from Kone in this area. Including the load weighing one, they have readily admitted to sabotage due to non paying customers, not the point. The car an ecospace is at the top floor and will not run down on insp,or anything else. Its level with the top floor. All lights but, start run, third from top? will light. 77 d is out and 77 u is lit. It acts just like a car does when it has a stuck normal. It doesn't generate a fault at all. I call my bud he comes in when I'm not there and fixes it in about 10 minutes. I think I got the 77 lights right as far as which one is lit and which one is out. I spent some time looking at this but not a whole lot cause I just call him and bam it's fixed. I don't have the kinda time to sit and figure it out and he likes messing with me. I don't usually get stumped to quickly. I figured out that alot of these drve problems are the relay in the back of the drive, pain to get to but making me alot of money,I take the condemned ones and fix em, lol. Anyone have this yet? I would like to finally get this monkey off my back.
