Hey everybody,

Little side topic since it’s not directly engine-related, but lately I’ve been reading spec sheets and manuals and noticed that one thing a Tech I can do that (as far as I know) no PC software can is talk to the ABS unit and get it to actuate. This is recommended as part of a full brake system bleed procedure. It’s just another message over ALDL so I’m not sure why this doesn’t seem to be possible. All the research I’ve done shows that people either buy a Tech I, take it to a dealer with a Tech I, or do it sketchy by driving down gravel and forcing the ABS to come on.

So, anyone know what “magic” the Tech I is doing on the ALDL for its ABS bleed procedure?
