Esp/asr

Does the ASR/ESP kick in on your bravos?

Before (last december) the yellow triangle used to flash when the wheels spinned but its not doing that anymore, the wheels are spinning when i accelearte hard it also spins when turning out of a side street onto the main road.. i thought the asr/esp elimantes wheel spins and cuts the power?

Ive got no errors messages either.

Re: Esp/asr

Hi, it should cut the power to your engine. Try the second gear and pull it hard on the slipery road.

Is your ASR led on maybe ?

Cheers,

Re: Esp/asr

well the power isnt really cutting out in 2nd? and no flashing light.
When it was drier if i was to take a corner to fast the power would cut out.

Im just concerned no yellow flashing light?

Re: Esp/asr

I don't have ASR on my Bravo, but had it on my old beemer.

I presume the ASR uses the same sensors as the ABS, and links in to the engine computer with the fly-by-wire accelerator. Obviously your accelerator is working. Is your ABS working OK? If you disconnect your battery for a couple of minutes your body computer and ECU will restart with hopefully everything working as it should.

When I were a mere lad....................................

I totally dismantled the engine of my Ford Cortina Mk1, every last nut / bolt / valve spring etc. Had the block rebored and the crank ground. Rebuilt it myself in my parents garage, and I mean house garage not car dealership. Started first time, ran perfectly, no oil leaks. A PROPER JOB.

All you need to do is disconnect the earth terminal. Thats the one with the exposed terminals, not the one under the black cover. You dont even need any tools. Theres just a little grey lever. Come on, you can do it!

Re: Esp/asr

Bear in mind that ASR works by sensing a difference in speeds of the driven wheels. If they're both spinning at the same speed, it won't notice, and won't cut in.

Also, don't confuse ASR with ESP, ASR stops wheelspin (most of the time), no more, no less. ESP is the clever bit that brakes individual wheels to counter over or understeer.

Re: Esp/asr

Exactly right.

And I say, a 150 HP M-jet engine will make front wheels slip, if you push full throtle in 2. gear and your ESP light should flash, especialy, if road is not dry. If not, I dont want you to panic, but your ASR is not working properly or is somehow disabled.

Cheers,
Paladin

I belive the ASR only cuts power when both wheels are spinning otherwise it applies breaking to the wheel thats slipping, could be wrong on that but it does tell you in the manual!

To cut power to each wheel independantly would require a limited slip diff would it not?

Re: Esp/asr

Yes, it its so. But even if only one wheel is braking, your light should come on. I have ESP/ASR on my 120 T-jet and ASR light comes on in 2. gear, if I push full throtle on a wet road.

Here is example of a multijet 150 from youtube.
Cheers,

Re: Esp/asr

Yep thats what mine did but last xmas when it was really icy.

Its never flashed like that before when i hammer it on a wet or dry road.

Ive disabled the asr and i could tell the difference but only a little bit.

The asr works because i can feel the car trying to grip the road from a racing start( in dry) but on the wet i can feel the wheels spinning beneath me... just no flashing triangle... strange.

Re: Esp/asr

My 150 MJet with ASR does the same .
I will wheel spin when putting my foot on the floor but I only get the light when on ice sometimes.
Like some people have said must be related to if both wheels are spinning.

You shouldn't lose any settings or software.

I would have thought the ASR compared the speed of the front wheels and the rears as well, much more likely to show up wheelspin!
