Just an FYI you can diagnose the 4wd functionality from the 4WD ECU pin outs. There is a write up online and if you follow it, it will take you right to the problem. Could be sensor, motor, etc. but highly recommend you figure it out from the 4WD ECU first.

Not sure if you're still reading these, but i have a quick question. I've got a 2003 Tundra. We bought it off a guy who told us it needed the rear actuator and that it was stuck in 4wd. I needed to use it immediately for work so I dropped the front driveshaft to be able to just use it in 2wd. Got what u thought was the right actuator, but it wasn't, I got the front one. Since it was on there I just left the new one on, and now a few months later I finally got the rear one and replaced it. Now I'm in 2wd, but when I hit the button it still flashes and flashes all the time. I can't really find this issue on the forums. So I guess my question is, do I need to reclock the rear actuator or is there likely something else in your opinion? I was able to move the shaft forward to get it in 2wd in the transfer case, and the front drive shaft is no longer trying to spin. But I really just don't know what to try at this point. I realize you're just doing this video to help others and doesn't mean you're an expert, but you know more about it than I do obviously, so any help would be much appreciated. Either way thanks for the video, I wish I would've known sooner that it was the same on Tacoma and tundras so I could've run up on this video sooner

I’ve found that the flashing 4wd light on the dashboard indicates that the system is somehow disagreeing with itself on what “drive” the vehicle is in. E.g. you moved the switch to x but you’re still stuck in y. What I would recommend you try doing is to make sure that the t-case actuator and the shaft agree on what position they’re in (you might have to remove the actuator and manually set it, as described in this video- no problem there). Additionally, set your dash switch to whatever the transfer case actuator and shaft are at. So, get all three of those things on the same page (getting them all in 2wd wouldn’t be a bad place to start). Furthermore (and I don’t think I stressed this enough in the video), you want to reset your ECU, which is behind the glove box on passenger side. There is a “fuse” looking thing plugging into the ECU that controls/powers/does the computer work for the 4wd actuation system. I can’t remember if it is labeled “4WD” or not; you may have to do research to figure out where exactly it is, but if my memory is correct then it will say 4WD on it. So unplug that, then set those three things I listed in agreement with each other, then plug that 4wd “fuse” back into the ECU and your whole system should then be on the same page with itself. The switch, the gears in the actuator, and the transfer case rod will all be in harmony, and the ECU should know what is going on. Then you can try to change it up with the switch and if all goes well then it’ll work! Good luck

Also those 2 switches(that plugs go into) could be bad. Many have removed (27mm) sprayed with maf while pressing them in/out, also check continuity while they're removed. Either cleanup fixed; replaced new; also 1 guy removed the washer on the more inside switch and so that was his fix as it then sat lower. He then sanded down said washer and put back in. So it's still sat lower and of course a washer is needed to protect internals. I'm doing mine now(02 4runner and it was corroded too/bought car used recently)

When you take the black cap off of the actuator, and let's say the rest of the actuator is still on the car, can you manually rotate that gear with your hand to go into 4 high or for low, effectively bypassing the motor if let's say your motor is dead? With that damage anything?
@DirtBikes_MathGarden

No you cannot because the rod is locked into place inside the transfer case. That’d be roughly the same as removing the actuator and trying to tap the rod into the right gear, but that’s not possible since that rod is locked into place inside the T-case. Cheers

@DirtBikes_MathGarden thanks. It was stuck in 4WD. Removed the two actuator sensors/ switches. Inspected, cleaned, and checked integrity, tested OK. Removed plastic actuator cover. Feared the worst as I noticed crack at the location of one of the three screws. Thankfully, the crack ran along outside of cover only, so it was really clean inside. There was no rust on the metal spirals, but there were a couple of large blobs of the white grease on a couple of areas. Wiped away blobs. Sprayed a little electrical cleaner. Buttoned everything down, and surprise, it came straight out of 4WD, no parts needed! I'm not brave enough to try and engage 4WD just yet. I will wait until I need it, up in Minnesota, so it won't be long 😆

I orientated the actuator to what it's like on the truck. If she's in 2wd the fork inside your tcase is all the way forward. You can freely spin the front driveshaft. So the only place for the fork left to go is backwards out outwards so orientate your gear wheel to the right so when you go 4x4 high it will move the wheel one turn left and it moves the fork outwards from the tcase so it appears the outer one is on plastic first

I believe that the OEM and most aftermarket rear actuators come set for 4H. But if you take/took your old one off and plan to attempt cleanup and retry old actuator, you can start in 2H for example. Read comment below from rcw3586 for how to use ohm meter to test whatever position you are in and want to have for reinstall, and make sure you ONLY have ONE pair of pins 3,4,5,6 with continuity at your chosen position. This video shows and describes how to line up the big-gear,etc with its splined shaft inserted in the no-contacts base piece, but it made more sense to me to try positions with the big-gear inserted into the motor+contacts+6-pin connector piece. Either way, it's a bit of a blind insertion attempt and I wonder how many teeth you could be "off", just a couple teeth difference makes a circumference difference approaching 1/2", which I think is a little more than the space/size of the "plastic portion" described in video 10:40 to 10:59, where the outermost sensor/finger wants to sit with no continuity so that in 2H there is NO continuity between pin4+6, but DOES have continuity between pin4+5. I'm fixating on 2H because I goofed and removed my original/flaky? actuator from a 2H situation and now I want to reinstall the original actuator which I un-timed by taking the big-gear,etc out.....re-timefor one last transition from 2H to 4H, so I can install a new actuator in the position of 4H like the OEM and most aftermarket new actuators come in. I sure don't want to take the new actuator apart any further than removing the small gear from the triangular access-plate area, to remove the new rod and re-use the unremovable rod (not taking transfer case apart!) Let us pray...

I took apart the TC actuator and cleaned up the contacts and pins as best as possible. I reassembled, DID NOT reset the ECU, and the lights went away. Drove around the block and tried to cycle through 4hi an 4lo and the blinking lights came right back. Gonna trouble shoot some more tomorrow, but do you think it could be from not orienting the pins correctly or maybe just needed to reset the ECU? OR should I just replace the whole damn thing ?

First, thank you for making this informative & entertaining video! Although I now see yours is a Tacoma while mine is a tundra, the parts look the same. Second, I had zero intention of removing the actuator but simply wanted to pop the cover to inspect the insides. Unfortunately, 2 of 3 bolts twisted off immediately (WI truck), and as I was messing with those without the cover on, the plastic gear and such came free from the gear. I’m unable to remove the entire actuator because the gear is still holding the rod in the transfer case. The bolts holding the triangular lid to access the gear are about to twist off but the lid is in a precarious location. You said to tighten the bolts holding the actuator to the transfer case before placing the gear but then that triangular cover for the gear isn’t accessible, on the tundra, at least. Any thoughts?
@DirtBikes_MathGarden
Жыл бұрын
That gear fits in there very snug. If you can’t get the triangle plate off to access the gear then I don’t see any way you’ll be able to get it all off. Id say try getting that triangle plate off and then work the gear out with some pliers. You should be able to get that gear in and out whether the actuator mounting bolts are tightened or not. It’s only important to tighten the actuator bolts before inserting the gear when reassembling.
