I believe it s a wiring issue, and possibly a bad ground or 2+... jojo I just discovered this, Crack in both wires that come from the fuse box and power the fic module. What do you recommend for the best repair on these wires? Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted February 24, 2022 Share Posted February 24, 2022 I believe, I would cut them to a clean spot and solder in new wire. I would also slide a heat shrink on the wires before I solder them.. I dont think that is a fused link, I believe it is just 2 wires into 1, under the heatshrink.. jojo 1 Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted February 25, 2022 Share Posted February 25, 2022 right.... but the connection itself is not a fused link.. so cut it, and remove the bad wire approx. 1/2" of wire, and solder in good wire if there is not enough to make the connection's.... jojo Quote Link to comment Share on other sites More sharing options...

When I cut them to repair and basically removed power to the fic module I turned the key on to see what codes I would get and got both blink codes 6-2 & 6-3, just like I do when thr truck shuts off. Soldered everything back together and it shut off again this morning when I was sitting in the truck. The electronic Malfunction light came on, I sat there for about 15-20 sec and the light went out and it fired up. It must be in that circuit? The only time I have ever gotten those two codes is when I cut those power wires and when I removed the fuse that sends power to the fic module. Any ideas of what I could try? I pulled out the shutdown relay that is between the fic module and the fuel rack actuator, turned the key on and that didn't throw a code so I don't think I am losing power to the fuel rack actuator. this has me scratching my head... could be a pin at the fic module connector or in the fic module... I don't want to keep throwing modules at it, I don't think Mack is going to help me at all with the fic module.
