1998 Ford Ranger Electric Crush Sensory Module

A few moments after starting the engine, a bell sound will start to peep. It peeps four times followed by a few minutes of silence and then again it peeps four times. It does it about four or five times.

Ford dealership charged me $180 dollars just to tell me that it's a Electric Crush Sensory Module. The cost to repair is prohibited as it's just an old pick-up and I am on a fixed income.

Can you help me locate this module and where can I go to get the schematics for this vehicle. I checked Ford Company but was informed that the VIN entered was not available at this time.
