Replaced the intermediate sector shaft in my steering column assembly last week. A couple Friday's ago the splines had stripped and came separated from the steering rack in a very scary moment. Luckily I had just gotten home and was in my parking lot when it occurred, so there really was no front page news.
Onur got the part to me by Monday and even helped me install it. However, I was not paying attention to where the steering wheel position was and got it a full revolution out of phase. Tried to go to work the next day and the VSC/ABS ECUs thought I was driving off the road when in fact I was going straight. Christmas tree lit up and wheels were braking left/right to the point I couldn't drive it. I turned around and limped back home. As long as I kept it under 5mph, the ABS would leave me alone.
Cut to this weekend...figured out I probably jacked up the clock spring assembly (spiral cable in TEQ speak) and got the part delivered in time to work on it this weekend (Onur again!). Put the front end up on stands and got my wheels straight, disconnected the sector shaft again and zero'd out the steering wheel with the steering rack. Reassembled the sector shaft. At this point I decided to remove the steering wheel to check the condition of the spiral cable. Carefully removed and opened up the plastic casing...the cable appeared to be intact, so I put it back on the steering column and drove to ACC to have them reinitialize the ECU (to clear my one remaining dash light - the airbag light). Steering was not truly aligned but I could at least drive it safely.
Got to ACC and pulled the steering wheel again, clocked another few degrees to get it fully aligned with the wheels. Then one of the techs hooked up the laptop to clear the codes and reinitialize. After a few seconds he said that it wasn't reading any of the ECUs at all - a bizarre reading all around. I said maybe I'll go ahead and install the new spiral cable assembly and see if that corrects this error. Seemed weird that the whole system seemed unreadable just because the spiral assembly might be bad, but it turns out that's what it was. Met up with Sam later and he confirmed that there is a tiny plastic pin inside the assembly that is designed to snap if over-rotated and thus throw the codes even if the cable isn't broken. I didn't notice that pin when I inspected it earlier.
Anyway, got it all back together and now I'm really good at disassembling the steering column...all you need is a 12mm & 19mm sockets and a T30 Torx driver, but only after you disconnect the battery (unless you want to see what an airbag looks like fully inflated, and no, that didn't happen

)
