the dsc sensor has died. I will look up exact location for you when i am at work and see if i can print out and scan the repair info on console removal. the self leveling fault is related to the dsc system since they share the info from the dsc/abs unit. The can bus is not sending any info to other control units. once can bus has started to talk to everyone again the leveling system will work again
