I have been advised that I may have off set the height sensor when I reinstalled it on the replacement upper control arm. I have pulled codes C1725 and C1917 so this makes sense to me.
I also checked with Firestone regarding SAS reset on this vehicle after they did the alignment. They were unsure about this requirement but offered to recheck the alignment. I am also unsure about SAS reset on an '01 Expy. Absent traction control I can't find information about SAS recenter. Anybody have experience with this?
