Turning off ETC

[JST]

I had heard that pumping the brake pedal 10 times within 10 seconds turned off the TC on a 07MY Defender. i must have heard/read it wrong as it didnt work when i tried it (maybe 10 times once every second?)

So was wondering how do you do it with out adding switches etc, and does it work for T5 platforms and RRV?

I have tried this a few times on my 2005 TD5, but without effect. I then resorted to removing the fuse and adding a switch.

No idea on the 2007, could be a different procedure but removing the fuse should definitely work.

On T5, you have a lot more elektrisckery and it's all interconnected, so I'd expect it to be a lot more complicated and wouldn't mess with it. On the other hand, chances are there is indeed a single fuse for the ABS/ETC, so it could be disabled. Not sure how terrain respons would react to it.

How about replacing the fuse with a blade type circuit breaker? It saves the hastle of taking out the fuse and loosing it but won't void your warantee by modifying the loom....

Sounds like a plan!

However, I used a relay linked to the ARB compressor to disengage the ETC and have since removed it all together.

i hear what you are saying but what i am after is the engineers way of turning off the ETC rather than us switching something. ie i want to be able to do it to an unmodified vehicle.

So was wondering how do you do it with out adding switches etc

I'm sure the engineers would just use a testbook.

[JST]

Maybe, but there is another way of doing it that the user can do. it was discussed at details either here or another forum and i cant find it on either.

James I'm with you on this. 10 times in 10 secs. I think it was Ian (Porny) that mentioned it. Once it's done do you get a light on the dash or an audible warning that it has been disengaged. If so then as when we get a solution I'll try it on my PUMA and report back the findings

[JST]

Whens TC is off you should get the TC light come on constantly on the dash.

i tried it in a puma, 10 times within 10 seconds (which doesnt sound right to me - what if you were cadence braking yourself off road?) anyway it didnt turn it off.

Will go and search the Defender forum again i think it was in there.

[Guest WALFY]

Cadence braking. 10 times in 10 secs would be pushing it a bit I think. Will pop out and try it now

EDIT Nothing. On the first application of the brake pedal the light goes out. Tried with the ign turned on and then with the engine running.

[JST]

Isn't a trick... or anything that special:

Traction Control can be disabled by operating the brake pedal ten times within ten seconds, when the ignition is turned on.

Traction Control will be re-activated when the ignition is turned off then on again.

Ian

Found it. defender forum here, quote above about it.

So should the engine be running? and what should the TC light do?

[JST]

Cadence braking. 10 times in 10 secs would be pushing it a bit I think. Will pop out and try it now

it should be, you can do 2 or 3 a second, well most people can!

I understand that when you're sat still in a motionless car it is easy but when it's moving towards the car/wall in front at a great speed I assume your pedal movements will be strong deep depressions of the pedal, therefore not achieving the 10 in 10

i disagree, push the pedal to the point of resistance, ie brakes starting to work then cadence it from there, ie you dont have to release the pedal all the way up between each 'stroke' - which is what alot of people do!

Every day a school day.

See my post above^^^^ tried with ign on and engine running. Lights go out with first application of brake pedal

[BogMonster]

Why would you be doing cadence braking in a vehicle with ABS?

[q-rover]

And why turn off the ETC?

[BogMonster]

And why turn off the ETC?

Possibly because it is F annoying and often triggers on the road with potholes, going over a kerb, loose gravel etc etc when it is not needed. I haven't tried disabling it in my Discovery yet so not sure if the "trick" works or not - too many vehicles means the Disco hasn't been out for a couple of weeks

[JST]

Why would you be doing cadence braking in a vehicle with ABS?

steep hill off road less than ABS tgt speed 8kph when ABS stops working.

And why turn off the ETC?

teaching how to pick a line rather than rely on vehicle electrics to help you out

i dont want to get into the ins and outs of why i just want to know how to do it.

ABS and TC lights or just TC light? ABS light should stay on on until you do over tgt speed then go out. TC lights should go out. i would expect the ABS light to stay on at what ever speed if the ABS was disabled. i think disabling the TC will also disable to the ABS but am not sure.

[Guest WALFY]

James

Just the TC light. ABS stays on till as you say reach a tgt speed.

[JST]

Its meant to do that, if its disabled i would have thought TC would come back on and stay on. i need to try on with the ign on but not running then take it for a drive/lift and axle see if TC works etc.
