You are watching: What does dtc mean in a bmw


I have read the owner manual and am an extremely confused around this. I have an E93 335i hand-operated trans.The default place is zero lights. Push DTC button and "DTC" mr up together "Activated."Does this mean I don"t have any type of kinda traction control in the default (no dash lights) position?When control in rain must I choose DTC? What around on Icy roads?See, I thought all this traction stuff was "ON" through default every time i start the car. Now, I"m kinda finding out that you have to turn on DTC. Well, miscellaneous is on through default. Since it won"t allow my wheel spin in gravel. Therefore what is on by default (no lights), and also what is changed when ns activate DTC?Last, ns guessing the holding the DTC switch turns all tools off right?
Default dtc is on. My understanding is to press the button when you space stuck in mud or several snow...Sent from mine Ally utilizing Bimmer App
But as soon as you push the DTC button, it then says "DTC Activated". As if DTC was deactivated by default or that I had no traction manage in the an initial place. For this reason you"re saying the for the safest driving, push nothing in hefty rain or icy conditions? but DO press DTC when basically stuck? choose an icy driveway. Ditch. Etc?

You use the default (no lights / no button push / full traction control) as soon as you"re driving, particularly if it"s slippery. The computer is on and also trying to store you going whereby you want.You use DTC (one button push) as soon as you want to allow some wheel spin without having actually the traction regulate system traction the strength off. The typical example of this is once you"re in snow or mud, room trying to gain going, and also will accept some wheel spin together the price that slogging forward.You usage "everything off" (press and also hold) as soon as you want to go spin the wheels and slide about for part fun.George

This.I don"t think a manufacturer would ever leave something prefer traction control up come the consumer to turn ON as soon as they think "it"s bad enough".

Ok thanks this is good information. I understand the hand-operated mentions this but IMO is really confusing. It"s evident that it"s confusing just by reading the differing opinions in the write-ups above. So ns think it"s safe to say the safest way to drive on slippery dangerous roadways (wet / ice) is to leave everything untouched. Press DTC once I need included wheel slippage (starting turn off on ice, in dirt etc).
Ok many thanks this is an excellent information. I recognize the manual mentions this however IMO is very confusing. It"s noticeable that it"s confusing just by reading the different opinions in the short articles above.So i think it"s safe to say the safest means to journey on slippery dangerous roads (wet / ice) is to leave everything untouched. Push DTC as soon as I need included wheel slippage (starting off on ice, in mud etc).
Pretty lot correct. However, you execute *NOT* desire wheel slip once *starting* out on ice cream or snow. You desire to use it in cases that continued application the power/throttle is vital - typically when you"re rise hills and also don"t desire DSC/TCS to throttle down or use brakes to attenuate slipping. Don"t forget that revolution friction is greater than DYNAMIC friction - ie, you"re much better off never slipping in the very first place.
This. As I heard it put by (I think) a Performance center instructor, "plenty of men have uncovered out the hard means they"re no "better 보다 The Button."" The computer"s attention never lapses.

You may uncover it helpful to summary activate DTCunder the adhering to special circumstances:> once driving uphill ~ above snow-covered roads,in slush or top top unplowed, snow-coveredroads> as soon as rocking a stuck vehicle free or startingoff in deep eye or on loose ground
> once driving with snow chains
When the surface you"re sitting on lacks enough cohesion to carry out any real purchase for the tires, DSC may intervene for this reason aggressively that you can"t acquire moving in ~ all. That"s one case where DTC have the right to help.

I can have this mixed up however I think:Traction regulate (DTC) is the capacity for the car to eliminate power from wheels that space slipping (rear wheel in this RWD vehicles).Stability regulate (DSC) is the capability for the auto to use the brakes to the wheels it deems essential to prevent the vehicle from spinning (oversteer, etc.)Combine the two and also you get some awesome drivability in dare that would certainly otherwise it is in a lot come handle.As a next note, ns really wish I had actually tried to acquire my 6er to spin out with all the nannies active. I just did the with every one of them off. Anyone else shot to turn out with DSC totally on?

What is confusing is the hatchet used. In one"s mind, DTC plot to stays clear of slipping (rear-wheel spin) when DSC prevents skidding. In reality, DSC curbs both skidding and slipping. By pushing the switch once, you rotate off the skid control, and also lessen the slipping control. By stop it, you turn off both.

Dynamic Traction manage (DTC).

Dynamic Traction manage (DTC) allows an ext wheel slip and thus a more dynamic driving layout with higher wheel traction and also DSC controlling stability. A small amount of turn on the drive wheels improves traction when pulling off from a standstill in eye or on loosened terrain.Dynamic Traction control (DTC) is a sub-function of the Dynamic Stability control (DSC) device that can be turn on and also off. DTC has actually two significant roles: to control traction and also to allow sports-style driving if providing active stability control.When the journey wheels start losing traction the DSC instantly begins stabilisation measures. The Dynamic Stability regulate system curbs the engine output and also stops slip on the wheels. In outstanding situations, however, a little amount that wheel slip have the right to be one advantage.When control in deep snow, slush or on loose terrain a little amount that wheel spin improves traction. Because that these occasions, as well as those once the motorists want a sportier control style, the DTC can be activated by pressing a button and this allows more slip and reduces the DSC"s curbing of the engine. The result: far better traction and more thrust.The DTC additionally makes steering on snow and ice-free roads much more dynamic. As soon as activated, the DTC enables sporty drivers more room come manoeuvre about curves 보다 the Dynamic security Control and also even permits managed drifts. The driver retains finish control end the auto in every situation and also the Dynamic stability Control"s stabilising procedures remain active even once the DTC is activated.
