Mitsubishi outlander 4x4 - 2005 light stays on when changing from 4x4 to 2 wheel drive


Try this quick fix solution.
Put vehicle in park or neutral, press the switch or turn the dial to 2H, put vehicle in reverse and reverse the vehicle aproximately 10m's or around 30ft.
Now drive vehicle forward, and this should unlock the 4wd mode.
If this doesn't work then your solenoid may need replacing.

The 4x4 light is blinking off and on


Typically this means that the truck is trying to engage 4wd, and can't. moving slightly should allow it to. If it doesn't, you have a problem.
Some models will flash the 4x4 light when you are in 4wd low. I am assuming it is a new thing, so this probably doesn't apply.
Turn your wheel fully to one side, and if it doesn't "grab" as you move, your 4wd is not functioning, and you need to take it to a mechanic, or grab a service manual, depending on your skill.

My service 4wd light keeps coming on in my 2000 cadillac escalade what should i do and what should it cost me??


when the 4WD light comes on you more likely have problems in the 4WD low switch circuit.well this is a dealership fix.because your 4WD is pcm controlled.when 4WD light turn on pcm detected the transfer case ratio was 0.8 - 1.2 or during condition 2 with the 4WD low switch not in 4WD low, transfer case in 4WD low,tcc commanded on, tcc slip speed from 100 to 3000 rpm, the pcm detected the transfer case ratio was 2.5 - 2.9 all conditions met for 10 seconds.see dealership has to check.many things will cause your 4WD light to turn on.dealership has to hook up diagnostic equipment to find your problem and fix it.hate to tell you.they will charge $100.00 or more to trouble shoot.then charge for labor and new part.call around and get a price check.it will be good if your vechicle has a extended warranty.

My 4 wheel drive is not working


does the light on the switch illuminate?if it does and the 4wd is not engaged look at the front diff factuator.removed it from the diff and engage the 4wd.the plunger should slowly come out.if it doesn't then the actuator.common problem.if the switch doesn't light up the it may be a encoder motor problem.check the 4wd fuse before first.

Kia sportage not going into 4 wheel drive when selected could this be diaphrams ?


with 4wd engaged check that the front tailshaft to the diff does not turn more than 45* if this is ok and no 4wd light check bulb switch and wiring. if light ok you will need to track down vacuum leak to drive hubs fault { common fault } you can check 4wd operation by raising one front wheel with handbrake on and car in netural select 4wd with engine running if 4wd ok raised wheel will not turn more than 45* by hand and will spin free when 4wd disconnected

My 4WD does not work, no light on dashboard


Two things happen when you select 4WD in this car. Moving the transfer lever physically selects the gears that will turn the prop shaft to the front diff. At the same time, a switch in the transfer box tells a pump to supply pressure to the diff engagement diaphragm in the front diff housing. This joins the diff spider gears to the front drive shafts. Once the air pressure remains fixed, the 4WD light on the dash will remain lit solid. Obviously, a number of problems could be causing your lack of 4WD. The most common would be the air line(s) from the pump (behind the front bumper, LH side usually) to the diff being pulled off, cut, or crushed during 4WD'ing. Failure of the pump, the relay control unit that powers the pump, the switch that turns it on and off are all possibilities too. As you have no 4WD lamp on the dash, you may have a blown globe too (unlikely) as this should flash if air pressure can't be maintained. You would still have 4WD! See if you can select 4WD with the ignition OFF and listen for any relay or pump noise. I'm not sure you can actually do this without the engine running, but it will be a lot easier to hear with the engine off. If you can hear the pump and everything else is OK, The problem may actually be in the diff. Good luck.

Service 4WD light illuminates on the dashboard message box


this is most commonly a electrical problem, does the speedometer read out correctly? if not it may be depending on if this is a Autotrak model, one f the two speeed sensors, or the acuator on the front diff, put the truck in 4wd, check the front dirveline to make sure it is engaing, if not your problem is in the t-case, if it does then move to the tires, if they are not engaged you have a problem with the actuator.

in most cases i have found the actuall 2wd 4wd switch to be the problem if you find that the switch is acting slow or you need to select the gear a few times before it shifts, then replace it these are very faulty
