mine did the same blinking sequence: 4 then 1, Right Hand Primary Crash Sensor Feed/Return Circuit Open-- turns out there was a "splash sheild" recall needed on both L & R sides. Cleared the warning light for 2+ years. Blinking has come back in the past 6-12 months from time to time, but this time around, I dont seem to care about it.
Have also heard the airbag/SRS light blinking is a sign of a battery going south. Same with windshield wipers coming on for no reason.
