Center Diff Auto Button

I own a Toyota L Touring Wagon. It's a 4wd. I've had no problem with it except that I think I should be getting more mpg form it. My question is about a button. It has a C. Diff Auto button on the right side of the steering wheel of the Dash. What does this button do?

    Thx Keemo 6. But the car is a full time 4 Wheel Drive. Are you sure that this is the all wheel drive option button?

The button is to lock the central diff to distribute the power 50/50 front to rear when in slippery conditions,
Normally with button off the drive system favours the front wheels.

That is a all wheel drive option button. however most fuel economy problems are related to poor maintenance practices. to boost fuel economy make sure you have regular tune ups have the fluids at proper levels have the filters changed ie(fuel,oil,and transmission).generally this should help your engine perform better.

2001 Toyota sequioa won't engage 4wd


For your four wheel drive to engage, the front diff actuator has to go into 4wd and then sends confirmation to 4wd ecu which in turn engages ur transfer case (center lock) If frame was just replaced, i check the connector on top of your front diff and make sure its plugged in as this would be a definite cause. Let me know how you go.

My 00 toyota land cruiser is stuck in 4wd the light indicating 4wd is not on , when i move the 4wd gear stick it moves perfect but the jeep is still in 4wd , it could have something to do with to do with...


Yes!! probably the front diff actuator is sticking , the wire that command the disengagement is not making contact properly, or the actuator itself is bad, also if you replace the tires with a size different from the manufactures that can create an engagement problem.

I just bought a RAV4 in France. Owners manual is


This is a manual center differential lock button for 4WD models.
When you push this button, it manually locks the front and rear axles. An amber C DIFF LOCK light should appear on the dash board when engaged.
Push it again and it will disengage. It may take a few seconds to disengage, and a beeping will be heard until the diff is unlocked.

The center differential lock is only meant to be used in emergency situations. Driving with it engaged at all times can damage your differential.

Where does diff lock display come on dash or button


diff lock displays on dash and is opperated by a dial to the left of the steering column. the center diff lock is operated by a button in the center dash and locks your center differential, making your front and rear driveshafts turn at the same speed. the front and rear differentials lock either your front or rear or both differentials making each wheel on the same axle turn at the same speed. all of these features are for increased traction in off road and wet conditions and situations

Blinking Center Diff Light while vehicle on the move.


The pajero has a limp mode for when there is an issue with the 4x4 system. The ECU apparently limits the vehicles capabilities until the problem is fixed. By turning the car off and on again you are reseting the fail-safe until it again triggers. The fault may be that a part of the drive train, secondary transfer case or auto locking hubs is not working correctly. For my Pajero, the auto hubs were not disengaging. This was later found to be caused by sticking air solendoids. Each solenoids cost was about $200 and there are two for the hubs. I was able to free them up by soaking the solenoids in CRC/ WD40 and a bit inside the air tubes as well plus repeatedly engaging and disengaging the 4x4 lever to activate the hubs. The auto hubs may not be the issue in your case but its worth a try.

Auto transmission fault on toyota landcruiser amazon


Howdy, My name is Mark, I am a mechanic (Auto trans and Diff specialist 23 years) this symptom is common with a broken driveline component, with full time 4WD and centre diff all the drive goes to the wheel with least resistance, (or to broken component) therefore when you engage difflock (Center) the drive then goes 2 ways front and rear so vehicle will drive, could be as simple as stripped spline in front wheel hub, broken CV joint etc. 1 major weakness these vehicles have is if driven with center diff lock engaged on high traction surfaces they do break the front diff, this will give the same symptom but you would of been aware of it when it happened.
To check where the drive is going chock all 4 wheels, park brake on, bonnet up, start engine let it idle down (after cold start), engage reverse (high range open center) from the front of vehicle and off to one side you can see the front axles, if one of them is turning that is where your drive is going, have someone to help you and under no circumstances place your self under or in driving path of vehicle.
Hope this helps

4WD


Look for damaged wires, or something bent, on the Auto Disconnect Device on the front axle before you do anything else. The 4WD HI light is not coming on because the front diff is not engaging.
Re 4 LO: In 4 LO, you ar NOT getting "4 LO", what you are really getting 2WD LO, because of the output gearing of the transfer case.
In any case, your front diff is not locking in, in either mode. The A.D.D. controls the 4 Hi lite.
