I’m trying to interpret a steering fault that isn’t in the PO999 category that I’ve seen before. Long story short, the car was impacted on one front corner hard enough to break a control arm. Everything was repaired, but the rack was not replaced (contrary to factory recommendation, I later found out). First track excursion, an inner tie rod pulled the (damaged) threads right out of the rack and led to a second impact--luckily damaging nothing more than a fender. After second impact, I’ve got “PSM loss” and “steering support limited” messages and codes. I replace the rack, clear the codes, and follow the end-range learning process of turning the wheel lock-to-lock. I still have the steering and related PSM code and no variable assist feeling, so now I’m trying to figure out whether it’s faulty electronics on the junkyard rack (10k mile car, rack and both tie rods had no damage), a bad steering angle sensor, or in need of some PIWIS calibration. Seems like the plastic sensor in the steering wheel hub could have easily been damaged, but I’d like to know what this code is all about to confirm. I have a diagnostics manual, but it only contains P and U codes. Google has not been my friend here either. Anyone know how I can find out what these 1114377 / 110109 codes mean?
Documenting for later search... Turns out it was a problem with the Durametric returning the wrong code. They've corrected that and now I'm getting 801101: Steering angle sensor, malfunction. Pretty much what I expected.
