I need to replace/reset the airbag comp in my 2008 TLC (aka "center airbag sensor"). It looks like the Toyota FSM is telling me that for a 2007 mfg date US model, I need to remove the entire AC unit from the vehicle, which involves not only draining the coolant and discharging the AC system, but also pulling apart the entire front dash, steering column, center console, etc. Is this for real??? Just to access the SRS computer? Please God someone tell me there's an easier way or I'm looking at the wrong manual or something!
