i have a reader but it wouldn't do voltage. used a multi-meter came up with 10 on one of the 3 wires. i'm going to chk my ficm next thank you guys for all the help. i will keep you posted on this diemma. thanks so much again
ok here goes! I tested my ficm, with key on 48 volts dc. the instructions say to read while truck is cycling on the reading dropped to 19 volts dc. i guess this means its a new ficm for me.
emailed a guy at circut board medics from sc told him my findings he said definite bad ficm. they charge around 350.00 to redo the ficm. does this seem high or is there a place that you guys trust and know.
I had mine replaced by Ford, over a year ago. They charged something like $800.00 plus labor for it. You have got a deal, but nothing on these trucks is cheap!
