I'm hoping it's not the rack. It seems incidental to electric pull at startup so I'm less convinced that there's failure at rack, plus, it's now throwing any other codes indicative of the rack failure. Could be battery. It's 5yrs old but I'm stumped because it's holding good charge and producing adequate voltage. There's another electrical anomaly that's been present for a while (disclaimer, this was a wrecked vehicle that was repaired and purchased by us 2 years ago). The passenger airbag light seems to be reversed...what I mean is that when the passenger belt is buckled, the airbag is disabled, and when the belt is unbuckled, the airbag is enabled.
