i have an 03 fx4 and sometimes the 4x4 doesnt work and if i take out the fuse #19 its back to normal .its seems like a electrical problem or something need help please.
The gearmotor encoder assembly is mounted externally on the transfer case. It drives a rotary cam which moves the mode fork and the range fork within the transfer case between the 4X4, 4X4 LOW, and 2WD range positions.
Central junction box (CJB) fuse 59 (30A)
Central junction box (CJB) fuse 27 (15A), 34 (10A)
what does that mean if i take the fuse #19 out is like reseting the security module .what causes that and most important how do i fix it . does that security module have something to do with an alarm.
19 powers the security module and your 4x4 module. I would check your module at the trans case for corrosion at the connection first then go from that.
When you pulled the 19 fuse you eliminated the power source for the module.
