Re: "Service 4WD Switch Error Message"
highly doubt its the VIC, dont mess with the chime module unless you want to lose your keyless entry on some models. Problem is with the switch in the tcase. Well not really the switch itself but everything together. solution, disconnect it. the purpose of the four wire is to accommodate different tcases (i.e. 231, 242, 249) which wires are connected corresponds to a different tcase.

your fluid for the tcase is transmission fluid, IIRC its ATF +3, to add fluid is pretty simple. On the rear of the case there are two fairly good sized bolts, the top is where you check your fluid level and add fluid, the bottom is to drain the case. Remove the top bolt fill until level with the bottom of the hole. in other words fill it until it runs out the hole and replace the bolt. hope this helps

the tcase is mounted directly after the transmission. its the unit where the front and rear driveshafts come together.

Re: "Service 4WD Switch Error Message"
Yea I had been having that same service 4 wheel drive switch message too and it was bugging the hell out of me. Then one day this random maroon box was just lying on the floor on the drivers side and it must have been the chime mechanism. The message still appears interminnently, but it doesnt beep anymore. Ive realized that Jeeps are the most random cars...

I pulled out the chime module on mine (94 laredo) and the beeping stopped when I now get the Service 4wd message. The thing is that I can't lock the doors with the keyless remote or with the buttons on the doors, just unlock them. This might sound stupid but to tell you the truth, I'd rather not have that stupid beeping sound all the damn time for no reason than to be able to lock my doors. That beeping is soooooooo damn annoying I feel like driving my jeep off a boat ramp into a lake half the time.

Re: Re: Re:
I think I have a somewhat easy solution to stopping the beeping, it has to do with the chime module, and you will loose all chimes, even the one that beeps when you leave the headlights on and the vehicle is off. I'm not entirely sure that it works, since I haven't been able to get the Service 4wd message to show up now that I've made a fix (which figures), but I didn't get beeping when the Turn Signal Left On warning came on the screen and I get no beeping when I open the drivers side door of the vehicle with the vehicle off and the headlights on, both of these being two other things I remember hearing the chime module in action.
You simply have to pull out the chime module (the maroon box under the front left side of the dash). Open up the chime module. It's pretty easy, just some snaps, you'll need something about 2 inches long with a radius of about 1/8' inch to get to some of the snaps, I used a nail. You'll see a green circuit board after opening up the maroon casing. Pull out the circuit board, it comes out easy. Underneath you'll see a thin, circular metal plate with a dark line through the middle of it. You'll have to unsnap the white cage holding it into place. I removed both the white cage and disk, which look like the peices that radiate the sound. Put the module back together and you can snap it back into place under the dash. Now you have removed the part of the chime module that makes the sound without even removing the chime module completely from your vehicle, so the door locks will still work. |

Re: Re: Re: Re:
I just unpluged the damn sensor plug from the transfer case. No more noise and Vehicle Information Module still works fine. This thing is getting old. Had to replace the ABS brake module also. Time to get another ride with a better brain

Re: "Service 4WD Switch Error Message"
My 1995 Jeep Grand Cherokee Laredo (6cyl, 4l) just started showing the "service 4wd switch" message, and then last night, it wouldnt shift out of first gear and eventually the transmission started slipping, and I couldnt go any faster than 5 mph. Had to get a tow. Please let me know if replacing the 4wd switch will fix this issue, or if I have a major transmission problem. Thanks.
