2015 Express 4500 ABS fuse location

[[email protected]]

ABS warning light will not go off. Youtube video suggest to first check the fuse and show a 25A fuse but my owners manual only shows 50A ABS motor and 40A ABS Module in engine compartment box and no ABS fuse under driver seat. Both are OK.

Have ordered a Scan tool but would still like to know if there is a 3rd fuse and where it is.

^{The owners manual should show the location of fuses and relays.  There should also be a rudimentary map of fuse and relay locations.  The relays are all the same, so you can swap them around for good testing, but, only change one at a time.}
