what is the fix for air bag code 41 The air bag light is flashing 4 times then 1

What is your question?

the air bag light flashes 4 times then pauses the flashes 1 time giving code 41 which means high resistance or open in the crash sensor circuit I only know of 2 sensors on the van, I have replaced the front one. I took the side one off of the frame cleaned it and the frame where it was grounded. I could not find the disconnect , must be in the frame.

What makes this problem better or worse?

it is the same code that the garage showed on their scanner
