when I removed my seat to fix the air bag wiring plug, I followed a guide on how/what to do and it said, make sure you disconnect the battery, also after you've finished insert your key... turn ignition on but not Engine.
then connect your battery, do not touch throttle and wait for throttle alignment to do its thing, then drive your car to get rid of all the lights and that, im sure there's a sequence with the steering as well (all way left / all way right)
