IFS switch help

[dydu]

hey all, my sct is showing P0231 code witch is Fuel Pump Secondary Circuit Low so i did some research and find out that the problem could be a damaged IFS switch or IFS switch relay (Inertia Fuel Shutoff), so could anyone tell me when i can find that IFS switch or IFS switch relay?? :headscratch:
thank you for any help

It should be behind the Passenger side kick panel. If you have the owners manual, it will show you all that stuff, including the location of the fuses and relays for the IFS.
