I have a 2001 SE. I got into an accident that set off both of the air bags. Replaced both drivers and passenger air bags and the control module. I get a flash code of 4 on the air bag warning light. Motor manual says this is a primary safing circuit failure. I cannot find where this circuit is located in the car. I also cannot find the crash sensors for this car. I have looked on the upper and lower radiator support cross members. Can anyone tell me where the safing circuit and crash sensors are on a post March 2001 focus or how to clear the flash code?
