5E19 - ASC/DSC CAN Data Error plus D3 - DME Idle speed control valve mechanical fault plus 91- EGS CAN torque reduction
JA: Do you have the torque specs?
Customer: I have been trying to figure out how to get them. I have an Autel MD802 that I am still learning to use. The ASC, Brake
Light (yellow) and sometimes check engine
light comes on when these codes appear.
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: I have replaced the AIC valve, the throttle boot (torn) and cleaned the throttle body plus i cleaned all of the wheel sensors. Only two were dirty.
JA: Anything else you think the mechanic should know?
Customer: The symptoms are the same before and after the idle air control was replaced. Did this at the dealers suggestion. I do my own work, but they are helpful most of the time. It is almost random when the lights come on, but the codes happen very soon after the car starts.
