Ford NO-CRANK Diag & Repair (2006 Ford Freestyle)

hey everyone welcome back to pine hollow auto diagnostics today we're working on a 2006 ford freestyle all-wheel drive apparently it's uh doing some guys doing some bodywork on it but he says it doesn't crank it was towed here he can manually energize the starter and the vehicle run so we're dealing with a no crank situation [Music] he said it has some kind of aftermarket system i see a little red light there i don't know if that's a ford installed unit or not but in our engine we don't have any uh trouble codes let's back out of here do a full code scan it just has the p 1000 ob system checks incomplete transmission memory and abs nope can communication bus fault with the abs low battery so nothing like anti-theft related um let's go right for the starter relay that's always the good fork in the road here's the wiring diagram so the starter relay there's the load side so it's hot at all times goes right to the starter and here we have a hot and start fuse and then the control side the ground is switched by the pcm whenever it receives the start signal and whenever you're in park okay so there's a starter relay on the load side first thing you want to do is just jump the two terminals see if this thing cranks and runs it does there's a busted just that vacuuming for now seems to run fine our charging system voltage comes up the smart charging system so there's nothing wrong with that so we're not worried about the load side here we worried about the control side so we want to put a test light and maybe this terminal and then that terminal and see do we get a hot you know this fuse right here hot and start so test light to ground test light works so here's one control pin move it over like that shut it off key on crank [Music] we have nothing there [Music] other fuse or other side [Music] so rather of these should be hot and start and key off key on nothing there okay that's definitely a problem so where does that come from if you use 2.14 in the smart junction box let's see what feeds that fuse in the start position all right so we're looking for this fuse f 2.14 in the smart junction box which hides under the steering column and we don't have anything useful well actually there it is f14 so if you're looking at it like this it would be the second fuse up in the second row that would be this seven and a half amp fuse right here so we want a test light on here when when we crank it now by the looks of it this fuse is a little bit crooked this one's a little bit crooked out of place let's see um see what happens when we crank it if we have voltage on there so i'll put a test light right here [Music] by the way the test light works we have a good ground so put it on the first pin there no no nothing on there let me just push these fuses in all the way here we go i hear something click in there no so this fuse let's take it out does not look blown do one more check here [Music] okay so now we can pop the relay in and just feed 12 volts to here and see if the car starts all right so i got my tesla connected to a power probe extension to battery positive so whenever it finds a ground it'll light up the key is on let's see what happens if we touch these pins here first pins nothing boom that's pretty cool bypass test with a test light and it didn't even light up all that much so we know that our problem now we're not getting this fuse is not hot and start if it was everything would work fine so the test light would basically check this entire system including the engine computer so this starter relay is getting power and ground to the control side it's turning on the starter everything works so why is our smart junction box not powering up this fuse in the start position of the ignition key that's the next step it's looking at this smart junction box here's the ignition switch and in start and on we have this light green violet wire coming down to the smart junction box that's the input the output to that fuse is on pin 24 it goes to starting and charging system and we can verify that by pin 24 right here so basically we have to check the input to the smart junction box on this light green and violet wire from the ignition switch let's try to find that all right so i removed this panel here and we can see our input wires so uh light green and violet is actually voltage supply and start and run so that works we we know that the fuel pump turns on and everything so let me uh if you turn the key on that works and start it stays on now the one that we're really interested in is voltage supply and start the dark green right next to it that would be this guy right here so pick is very handy for removing electrical tape and then isolating the wire that we want this guy right here so let's put the piercing probe on that one okay [Music] and key on and start nothing there on the input from the ignition switch so we're getting really close so on this wire again test light from battery positive now make sure a test light works we can do the bypass test and key on this car should start from here and it does that's awesome so we just did the bypass test from here so now we're going back to the ignition switch or if there's any aftermarket stuff between the ignition switch on this dark green wire and the smart junction box so we're eliminating things here you know starter is good relay's good smart junction box is good we're down to the ignition switch almost there so this aftermarket stuff here is apparently a ford motor company remote start system with keyless entry so this is factory installed just trying to see where all these wires go so we're interested in that dark green wire coming into our smart junction box where does that come from if it doesn't come from the ignition switch let's take a close look at the ignition switch see if we can find the dark green wire up there all right so now we're here's the ignition switch here's that dark green wire so test light again to battery negative make sure it works sure does let's put it right here in the green wire and crank it ah so i think i wiggled something and now the car starts let's see if we can reproduce the problem again that's gonna start every time dang [Music] oh that's pain the butt because now we can't really tell if the problem is here or wherever this goes what i did just now before turning the camera on was i had to test like the battery positive i had the key on and i stuffed it in here and the car started up [Music] so i'm suspecting we're just dealing with a bad ignition switch where the contact's in here but there's nothing really wrong with this car otherwise so good news for the owner i'm going to try to recreate the problem if i can't it's getting a new ignition switch to pop the ignition switch open it's keyed the little wide part is to the right if you're looking at it like this i guess these little guys fell out but there's uh i guess we can clean up those contacts figure out which one's uh making it you know the start we'll clean the contacts put it back together it starts and runs no problem so this happens again i'll recommend a new ignition switch to the owner but i don't see any problems with the remote start system as it's installed at the moment we could try to even unplug this thing and see what happens [Music] [Applause] [Music] it's [Music] so i think this can work independent of this module i don't see any other [Music] issues with it and we're done thanks a lot for watching we'll see you next time bye you
